USS Borie

USS Borie

Two ships in the United States Navy have been named USS Borie for Adolph Edward Borie.
- The first Borie (DD-215) was a Clemson-class destroyer commissioned in 1920, served in World War II and sunk following battle damage in 1943.
- The second Borie (DD-704) was an Allen M. Sumner-class destroyer, commissioned in 1944 and decommissioned in 1972.

United States Navy

The United States Navy (USN) is the branch of the United States armed forces responsible for naval operations. The U.S. Navy consists of 281 ships and over 4,000 aircraft. It has over half a million men and women on active or ready reserve duty. The United States Navy traces its origins to the Continental Navy, which the Continental Congress established during the American Revolutionary War. The United States Constitution, ratified in 1789, empowered Congress "to provide and maintain a navy." Acting on this authority, Congress ordered the construction and manning of six frigates; one of the original six, USS Constitution, familiarly known as "Old Ironsides," survives to this day. The War Department administered naval affairs from that year until Congress established the Department of the Navy on April 30, 1798. The Navy became part of the Department of Defense upon its establishment in 1947.

History of the Navy

Main article: History of the United States Navy History of the United States Navy The Continental Navy was established in Philadelphia by the Continental Congress on October 13, 1775, which authorized the procurement, fitting out, manning, and dispatch of two armed vessels to search for munitions ships supplying the British Army in America. The legislation also established a Naval Committee to supervise the work. The Continental Navy operated some 50 ships over the course of the American Revolutionary War, but no more than about 20 at one time. After the war, Congress sold the surviving ships and released the seamen and officers. Congress ordered the construction and manning of six frigates on March 27, 1794, and three years later welcomed into service the first three: USS United States, Constellation and Constitution. The frigates became famous in the War of 1812, where they unexpectedly defeated British Royal Navy forces several times. During the American Civil War, the Navy was an innovator in the use of ironclad warships, but after the war slipped into obsolescence. A modernization program beginning in the 1880s brought the U.S. into the first rank of the world's navies by the beginning of the 20th century. 20th century (middle) and USS Annapolis (SSN 760) (front)]] The Navy saw little action during World War I, but grew into a formidable force in the years before World War II. Japan unsuccessfully attempted to allay this strategic threat with a late-1941 surprise attack on Pearl Harbor. During the next three years, the U.S. Navy grew into the most powerful in the world. It is widely accepted that currently the United States Navy remains the most powerful in the world.

Organization

The Navy is administered by the Department of the Navy, led by the Secretary of the Navy (SECNAV). The senior naval officer, the Chief of Naval Operations (CNO), is the four-star admiral immediately under the Secretary of the Navy. The Secretary of the Navy and Chief of Naval Operations are responsible for organizing, recruiting, training, and equipping the Navy so the Navy is ready for operation under the command of the Unified Combatant Commanders. (Also see United States Armed Forces Organization.) President | SECDEF | ------------------- | | SECNAV | | | CNO Unified Combatant Commanders | | -------------------- | | | | Shore establishment Operating Forces (including fleets)

Fleets

The two main fleets are the Pacific Fleet and the Atlantic Fleet. Under these two organizations fall the numbered fleets.
- 1st Fleet - no longer active
- 2nd Fleet – Atlantic Ocean — Flagship Iwo Jima, Norfolk, Virginia
- 3rd Fleet – Eastern and Northern Pacific Ocean — Flagship Coronado, San Diego, California (In peacetime the Third Fleet has no ARG and the carriers in the area are either on their way to the Seventh Fleet or conducting training cruises, after an overhaul for example.)
- 4th Fleet – Disbanded.
- 5th Fleet – Middle East — Headquartered at Manama, Bahrain
- 6th Fleet – Mediterranean Sea — Flagship Mount Whitney, Gaeta, Italy
- 7th Fleet – Western Pacific and Indian Ocean — Flagship Blue Ridge, Yokosuka, Japan

Shore commands

In addition to afloat fleets, the Navy maintains several "Naval Forces Commands" which operate naval shore facilities and serve as liaison units to local ground forces of the Air Force and Army. Such commands are answerable to a Fleet Commander as the shore component of the afloat command. During times of war, all Naval Forces Commands augment to become task forces of a primary fleet. Some of the larger Naval Forces Commands include:
- Commander Naval Forces Korea (CNFK)
- Commander Naval Forces Marianas (CNFM)
- Command Naval Forces Japan (CNFJ)

Staff corps

In addition to the regular line commands of the navy, several staff corps are also maintained which augment the line community and whose personnel are assigned to both line and staff commands. The current staff corps of the United States Navy are as follows:
- Navy Supply Corps
- Navy Medical Corps
- Navy Medical Service Corps
- Navy Nurse Corps
- Navy Chaplains Corps
- Navy Civil Engineer Corps (Seabees)
- Navy Judge Advocate General (JAG)

Weapons

Ships

Main article: U.S. Navy ships See also List of ships of the United States Navy for a more complete listing of ships past and present. The names of commissioned ships of the U.S. Navy start with USS, meaning 'United States Ship'. Non-commissioned, civilian-manned vessels of the U.S. Navy have names that begin with USNS, standing for 'United States Naval Ship'. A letter-based hull classification symbol is used to designate a vessel's type. The names of ships are selected by the Secretary of the Navy. The names are usually those of U.S. states, cities, towns, important people, famous battles, fish, and ideals. The U.S. Navy pioneered the use of nuclear reactors aboard naval vessels; today, they power most U.S. aircraft carriers and submarines. See United States Naval reactor. As of January 2004, a relatively small number of ship classes accounted for the bulk of the U.S. naval fleet. These include:

Aircraft carriers

They put U.S. air power within reach of most land-based military power. The US Navy's carriers are much larger and more powerful than those of the rest of the world. See also: List of aircraft carriers of the United States Navy and List of escort aircraft carriers of the United States Navy. Modern aircraft carriers since CV-67 are typically named for living or dead politicians; previous aircraft carriers were named for battles and famous fighting ships of the Navy.
- Kitty Hawk class (1 ship)
- Enterprise — Norfolk, Virginia
- John F. Kennedy — Mayport Naval Station, Florida
- Nimitz class (9 ships, 1 under construction)
  - USS Nimitz (CVN-68)
  - USS Dwight D. Eisenhower (CVN-69)
  - USS Carl Vinson (CVN-70)
  - USS Theodore Roosevelt (CVN-71)
  - USS Abraham Lincoln (CVN-72)
  - USS George Washington (CVN-73)
  - USS John C. Stennis (CVN-74)

Amphibious assault ships

The largest of all amphibious warfare ships amphibious assault ships resemble small aircraft carriers; capable of V/STOL, STOVL, VTOL tiltrotor and rotary wing aircraft operations; contains a welldeck to support use of Landing Craft Air Cushion and other watercraft. Amphibious assault ships are typically named after World War II aircraft carriers, a name source kept over from the earliest ones, which were converted WWII carriers.
- Wasp class (7 ships)
- Tarawa class (4 ships active, 1 decommissioned)

Amphibious transport docks

Amphibious transports are warships that embark, transport, and land elements of a landing force for a variety of expeditionary warfare missions. Amphibious transport docks are named for cities, except for USS New York (LPD-21), which is named for the state of New York and USS Somerset (LPD-25), which is named for Somerset County, Pennsylvania.
- San Antonio class (3 launched, 2 under construction, 3 planned, 2 projected)
- Austin class (10 ships active, 1 Decommissioned, 1 converted to AGF)

Submarines

:Main article: Submarines in the United States Navy There are two major types of submarines, ballistic and attack. Ballistic subs have a single, strategic mission: carrying nuclear SLBMs. Attack submarines have several tactical missions, including sinking ships and subs, launching cruise missiles, and gathering intelligence. Sea attack submarines are typically named for cities; land attack submarines (Virginia and Ohio-class boats) are typically named for states. Earlier attack submarines were named for fish, while earlier ballistic missile submarines were named for "famous Americans" (although many of these were actually foreigners).
- Ohio class (18 in commission) — ballistic missile submarines, 4 to be converted into guided missile submarines
- Virginia class (1 in commission, 3 under construction, 2 on order) — attack submarines
- Seawolf class (3 in commission) — attack submarines
- Los Angeles Class (51 in commission) — attack submarines

Cruisers

Guided missile cruisers can conduct air warfare, surface warfare and undersea warfare. All modern cruisers are named for battles. Previous cruisers were either named for cities (until CG-12), the redesignated frigates were named for naval heroes (CG-15 to CG-35) or states (CG-36 to CG-42).
- Ticonderoga class (23 in commission) — first ships to carry the Aegis combat system

Destroyers

See also the List of destroyers of the United States Navy. All destroyers have been named for naval heroes since USS Bainbridge (DD-1).
- Arleigh Burke class (44 in commission as of June 2005) — first ship class with comprehensive design for stealth technology.

Frigates

Modern frigates mainly perform anti-submarine warfare and escort other ships. The U.S. Navy is gradually retiring its frigates; some of their jobs will be performed by the nascent littoral combat ship. [http://peoships.crane.navy.mil/lcs/] Named, like the destroyers, for naval heroes.
- Oliver Hazard Perry class (30 ships in commission)

Battleships

All U.S. battleships have been retired, although two Tomahawk-capable ships remain in "Inactive" Reserve. They are maintained in accordance with the National Defense Authorization Act of 1996. Current plans in the United States Navy call for keeping the battleships on the NVR until the naval surface fire support gun and missile development programs achieve operational capability, which is expected to occur sometime between 2003 and 2008. All battleships except USS Kearsarge (BB-5) were named for states.
- Iowa class

Early vessels


- USS Constitution — "Old Ironsides," oldest commissioned warship afloat
- USS Monitor — first US ironclad warship, also first rotating turret
- USS Merrimack — a wooden warship rebuilt by the Confederates as the ironclad CSS Virginia
- USS Alligator — the first submarine of the Civil War, but sunk while being towed during a storm.
- CSS Hunley — First submarine to sink a ship in a combat engagement, though it sunk in the aftermath as well. Built by the Confederates near the end of the Civil War. Sank USS Housatonic with a spar-mounted torpedo.

Harbor defense

The United States Navy has, in the last few years, greatly expanded its harbor defense forces in response to the War on Terrorism. The main components of Naval Harbor Defense include:
- Inshore Boat Units (IBUs)
- Mobile Inshore Undersea Warfare Units (MIUWUs)
- Special Boat Units (SBUs)

Special warfare

The Navy Seals are the U.S. Navy's primary special warfare units whose purpose is to engage in "special activities other than war". The Navy also maintains an EOD Corps (Explosive Ordnance Disposal) as well as a small corps of Surface Warfare personel known by the designator "Special Operations Underway".

Submarine warfare and nuclear deterrence

The submarine has a long history in the USN. It began in the late 19th century, with the building of the SS-1, USS Holland. The boat was in service for 10 years and was a developmental and trials vessel for many systems on other early submarines. The submarine really came of age in World War I. The USN did not have a large part in this war, with its action mainly being confined to escorting convoys later in the war and sending a division of battleships to reinforce the British Grand Fleet. However, there were those in the USN submarine service who saw what the Germans had done with their U-boats and took careful note. Doctrine in the inter-war years emphasised the submarine as a scout for the battle fleet, and also extreme caution in command. Both these axioms were proven wrong after the attack on Pearl Harbor in December 1941. The submarine skippers of the fleet boats of World War II waged a very effective campaign against Japanese merchant vessels, doing to Japan what Germany failed to do to the United Kingdom. They were aggressive and effective, and operated far from the fleet. In addition to their commerce raiding role, submarines also proved valuable in air-sea rescue. There was many an American aircraft carrier pilot who owed his life to the valour of USN submarine crews, including future U.S. President George H. W. Bush.

Navy revolutions

After WWII, things continued along much the same path until the early 1950s. Then a revolution, that was to forever change the nature of the submarine arm occurred. That revolution was USS Nautilus. The Nautilus was the first nuclear-powered submarine. Up until that point, submarines had really been, at their most basic level, torpedo boats that happened to be able to go underwater. They had been tied to the surface by the need to charge their batteries using diesel engines relatively often. The nuclear power plant of the Nautilus meant that the boat could stay underwater for literally months at a time, the only limit in the end being the amount of food that the boat could carry. Another revolution in submarine warfare came with USS George Washington. Nuclear powered, like Nautilus, George Washington added strategic ballistic missiles to the mix. Earlier submarines had carried strategic missiles, but the boats had been diesel powered, and the missiles required the boat to surface in order to fire. The missiles were also cruise missiles, which were vulnerable to the defences of the day in a way that ballistic missiles were not. George Washington's missiles could be fired whilst the boat was submerged, meaning that it was far less likely to be detected before firing. The nuclear power of the boat also meant that, like Nautilus, George Washington's patrol length was only limited by the amount of food the boat could carry. Ballistic missile submarines, carrying Polaris missiles, eventually superseded all other strategic nuclear systems in the USN. Deterrent patrols continue to this day, although now with the Ohio class boats and Trident missiles. Trident missile]] Given the lack of large scale conventional naval warfare since 1945, with the USN's role being primarily that of power projection, the submarine service did not fire weapons in anger for very many years. The development of a new generation of cruise missiles changed that. The BGM-109 Tomahawk missile was developed to give naval vessels a long range land attack capability. Other than direct shore bombardment, and strikes by aircraft flying off carriers, the ability of naval vessels to influence warfare on land was limited. Now, instead of being limited to firing shells less than 20 miles inland from guns, any naval vessel fitted with the Tomahawk could hit targets up to 1,000 miles inland. The mainstay of the Tomahawk equipped vessels in the early days of the missile's deployment were the Iowa class battleships, and the submarine fleet. The Tomahawk was first used in combat on 17 January 1991, on the opening night of Operation Desert Storm. On that day, for the first time since the surrender of Japan in 1945, an American submarine fired in combat, when Tomahawks were launched by US boats in the eastern Mediterranean. Since then, the Tomahawk has become a staple of American campaigns. It has seen use in no less than three separate wars. It has also been exported to the United Kingdom, which has also fitted it to submarines. The Tomahawk has seen a change in the design of attack submarines. At first it was fired through torpedo tubes, but more recent US boats have been fitted with vertical launch systems to enable them to carry more of the weapons. In the early 21st century, the USN submarine fleet is made up entirely of nuclear powered vessels. It is the most powerful of its type in the world. However, there are those who worry that there are not enough boats in the fleet. As with other branches of the US military the budget cuts of the late 1980s and the early 1990s, as the Cold War ended, followed up by the War on Terrorism, have left little or no slack in the system. This point is illustrated by the fact that in 2003, for the first time since 1945, a US submarine made two back-to-back war patrols.

Personnel

Commissioned officer

Commissioned officers in the Navy have paygrades from O-1 to O-10. Officers with superior performance may be promoted. Officers between O-1 and O-4 are called junior officers, O-5 and O-6 are called senior officers, and O-7 to O-10 are called flag officers. See U.S. Navy officer rank insignia for a complete list of paygrades and corresponding ranks. Commissioned officers belong to one of the following communities:
- Unrestricted line: Surface Warfare, Aviation Warfare, Submarine Warfare, Special Warfare, Nuclear
- Restricted line: Engineering Duty, Aerospace Engineering Duty, Aerospace Maintenance Duty, Cryptologic, Naval Intelligence, Public Affairs, Meteorology and Oceanography, Information Professional, Human Resource
- Staff Corps: Supply Corps, Medical Corps, Medical Service Corps, Dental Corps, Nurse Corps, Chaplain Corps, Civil Engineer Corps, Judge Advocate General Corps, Navy Band Corps The term "line" officer means someone who may command a warship or an aviation unit. It is a carryover from the 18th-century British tactic of employing warships in a "line" to take advantage of cannons on each side of the ship. The captains of such vessels commanded "ships of the line." Today, all Navy line officers wear a star on the sleeves of uniforms near the cuff braid that denotes rank. Staff officers wear different insignias. Note: Marine Corps officers, also part of the Department of the Navy, are all considered "line" officers because they are qualified as troop commanders in addition to their specialties. Commissioned officers originate from the United States Naval Academy, Navy Reserve Officer Training Corps (NROTC), Officer Candidate School (OCS), direct commission, and other commissioning programs (such as [https://www.sta-21.navy.mil/ Seaman to Admiral-21] and Limited Duty Officer programs).

Enlisted

Enlisted members of the Navy have paygrades from E-1 to E-9. Enlisted members with superior performance may be advanced in paygrade. Two notably significant advancements are Seaman to Petty Officer Third Class (E-3 to E-4) and Petty Officer First Class to Chief Petty Officer (E-6 to E-7). Advancement to Chief Petty Officer is especially significant, marked by a special initiation ceremony. See U.S. Navy enlisted rate insignia for a complete list of the paygrades. All new active-duty enlisted members receive basic training ("boot camp") at the Recruit Training Command in Great Lakes, Illinois. Those who have a contract for a specific rating continue onto "A" schools for training in the rating. Those who don't have a specific rating go into the fleet to learn on the job and later strike for a rating. Some members may go to additonal training in a "C" school either before a tour of duty, or after a tour of duty. A "C" school assigns a member a Navy Enlisted Classification code, or NEC, which shows that a sailor is able to perform a specific task requiring that NEC, such as NEC 2780 - Network Security Vulnerablity Technician. Enlisted members of paygrades E-4 and above are said to be "rated" and have a rating: an occupational specialty. As of June 2005, there are more than 50 ratings, including Boatswain's Mate, Quartermaster, Engineman, Damage Controlman, Electronics Technician, Information Systems Technician, Air Traffic Controller, Fire Control Technician, Gunner's Mate, Sonar Technician, Construction Mechanic, Hospital Corpsman, Yeoman, Disbursing Clerk, Culinary Specialist, Photographer's Mate, Musician, Master-at-Arms, Aviation Electronics Technician, and Cryptologic Technician. Some ratings have subspecialties acquired either through an initial "A" school for training (such as Cryptologic Technician Technical and Cryptologic Technician Collection) or through a separate "C" school (such as Aviation Electronics Technician Organizational and Aviation Electronics Technician Intermediate.)

Qualifications

Sailors prove they have mastered skills and deserve responsibilities by completing Personal Qualification Standards (PQS) tasks and examinations. Among the most important is the "warfare qualification," which denotes a journeyman level of capability in Aviation Warfare, Special Warfare, Surface Warfare, or Submarine Warfare. Many qualifications are denoted on a sailor's uniform with U.S. Navy badges and insignia.

Sea Warrior

Launched in 2003 as part of the Navy's [http://www.chinfo.navy.mil/navpalib/cno/proceedings.html Sea Power 21] transformation plan, Sea Warrior is intended to link the fleet's personnel processes (recruiting, training, and assigning) with acquisition processes (buying ships, aircraft, etc.) in a way that also improves each individual sailor's ability to guide his or her own career in a satisfying direction. The aim is to more efficiently muster the right number of sailors with the right skills and seniority at each ship, squadron, and duty station. Sea Warrior is led by the Chief of Naval Personnel[http://www.chinfo.navy.mil/navpalib/people/flags/biographies/hoewinggl.html], and the commander of the [https://www.cnet.navy.mil/netc/netc.html Naval Education and Training Command].

Naval culture

Navy sailors are trained in the core values of Honor, Courage, Commitment. Sailors cope with boredom on long cruises of six months to a year, and cherish their time in their home ports, as well as vacations at ports abroad.

Naval jack

Chief of Naval Personnel Chief of Naval Personnel Chief of Naval Personnel The naval jack of the United States is the First Navy Jack, first used during the American Revolutionary War. On May 31, 2002, Secretary of the Navy Gordon England directed all U.S. naval ships to fly the First Navy Jack for the duration of the War on Terrorism. Many ships chose to shift colors on September 11, 2002. The jack is flown from the bow of the ship and the ensign from the stern when the ship is moored or anchored. When underway, the ensign is flown from the main mast. The former naval jack was a blue field with 50 white stars, identical to the canton of the ensign, both in appearance and size. A jack of similar design was first used in 1794, though with 13 stars arranged in a 3–2–3–2–3 pattern.

Naval jargon

Main article: Military slang A distinct jargon has developed among sailors over the course of the last four centuries. Naval jargon is spoken by American sailors as a normal part of their daily speech. There are three distinct components of Naval jargon:
- Words that are unique to sailing and have no use in standard English, such as yardarm, bow, and stern.
- Archaic English that remains common in naval jargon, such as "aye" (the common English word for "Yes" until the 16th century), "Fo'c'sle" (from Fore Castle), and Bo'sun (from "Boat Swain", swain being Middle English for a young man or a servant).
- Modern jargon, such as "Bird" to refer to missiles, or 1MC. See U.S. Navy slang for more information. Also see Covey Crump.

USS Borie (DD-215)

The first USS Borie (DD-215) was a Clemson-class destroyer in the United States Navy during World War II. She was named for Secretary of the Navy Adolph E. Borie. Borie was launched 4 October 1919 by William Cramp and Sons; sponsored by Miss Patty Borie, great-grandniece of Secretary Borie; and commissioned 24 March 1920, Lieutenant Commander E. F. Clement in command. In April 1920 Borie joined the United States Naval Detachment in Turkish Waters for service in the Black Sea. The following year she reported to Destroyer Division 38, Asiatic Fleet, and for the next four years alternated between the Philippine Islands, during the winter and Chefoo and Shanghai, China, during the summer. She then returned home and patrolled in the Caribbean until the spring of 1927 when she made a cruise to Europe. Borie remained with the Atlantic Fleet until 1929 when she began a three-year tour with the Asiatic Fleet. Following conversion to a Squadron Leader at San Diego (1932-33) she joined Destroyer Squadron 2, Battle Force. She remained in the Pacific on normal destroyer duty until late 1939 and then transited the Panama Canal to join the Neutrality Patrol. After the breakout of hostilities between the US and the Axis powers, she served first on the Inshore Patrol, 15th Naval District, in Panama Bay, and later on patrol and escort in the Caribbean. On 26 June 1943 the destroyer departed the Caribbean and on 30 July put to sea as a member of the offensive antisubmarine group built around Card (CVE-11). Borie completed three patrols with the Card group. On 1 November 1943, during the next patrol, she engaged the German submarine U-405 at 49°00' N., 31°14' W. The destroyer initially fired depth charges, after which the submarine came (was probably forced) to the surface. Borie then rammed U-405. After the ramming the two ships remained locked together and exchanges of small arms fire took place. Finally, U-405 and Borie separated and the submarine sank with the loss of all 49 crew members. Borie lost 27 crew members and was too badly damaged by the collision to be towed to port; she was sunk by Barry (DD-248) the next day. Borie received three battle stars for her World War II service as well as the Presidential Unit Citation (US) for her actions in the Card group. See USS Borie for other ships of this name.

Clemson class destroyer

The Clemson class was a series of 156 destroyers which served with the United States Navy from after World War I into World War II. The Clemson class ships were commissioned by the United States Navy from 1919 to 1922, built by New York Shipbuilding Corporation and the Bethlehem Steel Corporation, some with alarming speed. The Clemson class was a redesign of the Wickes class, and was the last class of flush-decker destroyers to be built for the United States.

History

Fourteen ships of the class were involved in the Honda Point Disaster in 1923, of which seven were lost. Most never saw wartime service, as many were decommissioned in 1930 and scrapped as part of the London Naval Treaty. Nineteen were transferred to the Royal Navy in 1940 as part of the Destroyers for Bases Agreement where they became part of the Town class. Others were upgraded or converted to highspeed transports or seaplane tenders and served through World War II.

Destroyer

:This article is about the warship. For other meaning, see destroyer (disambiguation). destroyer (disambiguation) destroyer]] In naval terminology, a destroyer is a fast and maneuverable yet long-endurance warship intended to escort larger vessels in a fleet or battle group and defend them against smaller, short-range attackers (originally torpedo boats, later submarines and aircraft). At the beginning of the 21st century, destroyers are the heaviest surface combatants in general use, with only two nations (the United States and Russia) operating cruisers and none operating battleships or battlecruisers.

Genesis of the destroyer

The destroyer originated in Britain and Japan in the last years of the 1880s, and became firmly established after the Chilean Civil War of 1891 and in the Sino-Japanese War (1894–1895). In those conflicts, a new type of ship proved to be devastatingly effective—the swift, small torpedo-boat invented by John Ericsson. These small boats had speed greater than that of the larger ships, and could dash in close to them, loose their torpedoes, and dash away. While normally a small, short-range boat of this sort would be easily destroyed long before getting into range, they could be operated within a fleet with larger ships as long as the fleet was close to base. In this case the defending force had to choose which set of targets to attack: the larger ships which they were built to counter, or the smaller torpedo boats which were charging in to attack. Yet this one-two punch cost almost nothing to the attacker, as the small torpedo boats were very inexpensive. The world's navies recognized the need for a counter weapon and developed the torpedo-boat destroyer. The basic idea was to have a screen of ships that were as fast as the torpedo boats, but armed with guns instead of torpedoes. They would operate at a distance from the main fleet of capital ships to keep the torpedo-boats from ever getting into torpedo firing range. However it was clear even at the time that this concept had problems of its own. The ship would indeed be capable of holding off an attack by torpedo boats (which typically have no guns of their own), but while operating away from the fleet they would be easy targets for any other capital ship. Thus they were often given torpedoes of their own. Another problem was that the torpedo-boats were short ranged and thus easy and cheap to produce. However the destroyers had the problem of needing to operate as a screen for the fleet. This required them to have the speed and range of the battleships, so destroyers were often much larger than the boats they were designed to counter.

First designs

battleships (1887)]] The first effective design of a torpedo-boat destroyer emerged in 1885 with the Japanese Kotaka, a Japanese-designed, but British-built, torpedo-boat with expanded capabilities and performances, which "was the forerunner of torpedo-boat destroyers that appeared a decade later" (Kaigun, David C. Evans). Designed and ordered in 1885, she was transported in parts to Japan, where she was assembled and launched in 1887. She was armed with four 1-pounder (37 mm) quick-firing guns and four torpedo tubes, reached 19 knots, and at 203 tons, was the largest torpedo boat yet designed. In her trials in 1889, Kotaka demonstrated that she could go beyond a role of coastal defense, and was capable of following larger ships on the high seas. The Yarrow shipyards, builder of the parts for the Kotaka, "considered Japan to have effectively invented the destroyer" (Howe). Yarrow shipyards Almost immediately after the order of the Kotaka was placed, Fernando Villaamil of the Spanish Navy also placed an order for a torpedo-boat destroyer in November 1885, with the British builder James and George Thompson, of Clydebank, also nearby the Yarrow shipyards. The ship, named Destructor, was laid down at the end of the year, launched in 1886, and commissioned in 1887, thereby becoming the first torpedo-boat destroyer to be completed. Her displacement was 380 tons, and she was equipped with triple expansion engines generating 3,800 HP, for a maximum speed of 22.6 knots. She was armed with one 90 mm Hontoria cannon, four 57 mm Nordenfeldt cannon, two 37 mm Hotchkiss guns and 3 Schwartzkopff torpedo tubes. Her complement was 60 men. Hotchkiss).]] The next effective design of torpedo boat destroyer, with the range and speed to keep up with battleships, was the Havock class of two ships of the Royal Navy, developed in 1892 under the newly appointed Third Sea Lord Rear Admiral "Jackie" Fisher, and launched in 1893. The Havock had a 240 tons displacement, a speed of 27 knots, and was armed with a single 12-pounder (76 mm) gun, three 6-pounders (57 mm), and three 46 cm torpedo tubes. The torpedo boat destroyer later on took over the role of the smaller torpedo boats, performing torpedo attacks on fleets, such as the devastating Japanese attack on the Russian fleet in Port Arthur at the opening of the Russo-Japanese War in 1904, and attacks in the Pacific theatre of World War II.

World War I

Torpedo Boat destroyers grew in size and effectiveness in the early part of the 20th century. Innovations such as turbine propulsion, oil-fired rather than coal-fired boilers, and longer ranged "heater" torpedoes led to effective ships being designed by Britain and Germany. The threat evolved by World War I with the perfection of the submarine. In general, the submarine, or U-boat, of the era was nothing more than a submersible torpedo boat. This change allowed the submarine to hide from the guns of the destroyers and close to firing while underwater. This led to an equally rapid destroyer evolution during the war, which was quickly equipped with depth charges and sonar for countering this new threat. At the end of the war the state of the art was represented by the British V and W class destroyer.

Inter War

V and W class destroyer Destroyer construction continued during the inter war period initially with designs evolved from the British V & W Class. A major innovation came with the Japanese Fubuki class destroyers or special type of 1928, which introduced enclosed turrets capable of anti-aircraft fire and the 24-inch (60cm) oxygen fuelled Type 93 torpedo. Most other nations replied with similar larger type ships examples include the US Porter-class destroyer leader and the British Afridi-class destroyer (commonly called "Tribals") The submarine threat had been insufficiently realized, however; while sonar (or ASDIC)was fitted, training in its use was indifferent. Weapons to attack submarines changed little, and ahead-throwing weapons, a need recognized in WW1, had made no progress.

World War II

By World War II the threat had evolved once again. Submarines were more effective, and aircraft had become important weapons of naval warfare; once again the fleet destroyers were unequipped for combatting these new targets. They were re-equipped with new anti-aircraft guns, radar, and ahead-throwing ASW weapons, in addition to their existing light guns, depth charges, and torpedoes. By this time the destroyers had become large multi-purpose vessels, expensive targets in their own right rather than expendable vessels for the protection of others. This led to the introduction of smaller and cheaper specialized anti-submarine warships by the Royal Navy: corvettes and later frigates, while the US introduced destroyer escorts.

Post War

Some conventional destroyers were completed in the late 1940's and 1950's which built on wartime experience. These vessels were significantly larger than wartime ships and had fully automatic main guns, unit Machinery, radar, sonar, and antisubmarine weapons such as the Squid mortar. Examples include the British Daring-class, US Forrest Sherman-class, and the Soviet Kotlin-class destroyers. Some World War II-vintage ships were modernised for anti-submarine warfrare, and to extend their service lives, to avoid having to build (expensive) brand-new ships. Examples include the US FRAM I programme and the British Type 15 frigate.

The Missile Age

The advent of surface-to-air (SAM) missiles and surface-to-surface (SSM) missiles, such as the Exocet, in the early 1960's changed naval warfare. Guided missile destroyes (DDG in the US Navy) were developed to carry these weapons and protect the fleet from air, submarine and surface threats. Examples include the Soviet Kashin-class, the British County-class, and the American Charles F. Adams-class.

Modern destroyers

Charles F. Adams-class The United States commissioned its first destroyer, USS Bainbridge, Destroyer No. 1, in 1902. In the US Navy, destroyers operate in support of carrier battle groups, surface action groups, amphibious groups and replenishment groups. Destroyers (with a DD hull classification symbol) primarily perform anti-submarine warfare duty while guided missile destroyers (DDGs) are multi-mission (anti-submarine, anti-aircraft, and anti-surface warfare) surface combatants. The relatively-recent addition of cruise missile launchers has greatly expanded the role of the destroyer in strike and land-attack warfare. As the expense of heavier surface combatants has generally removed them from the fleet, destroyer tonnage has grown (a modern Arleigh Burke-class destroyer has the same tonnage as a World War II light cruiser). Arleigh Burke is billed by her builders, the Bath Iron Works, as ton-for-ton the most powerful warship in history. Bath Iron Works destroyer]] One class of destroyers is currently in use by the US Navy: the Arleigh Burke class. The last Spruance class destroyer in service, USS Cushing (DD-985), was decommissioned on September 21, 2005. The Zumwalt class were planned to replace them; on November 1, 2001, the US Navy announced the issuance of a revised Request for Proposal (RFP) for the Future Surface Combatant Program. Formerly known as DD 21, the program will now be called DD(X) to more accurately reflect the program purpose, which is to produce a family of advanced technology surface combatants, not a single ship class. DD(X) is no longer called Zumwalt class, and is much larger than traditional destroyers, being nearly three thousand tons heavier than a Ticonderoga-class cruiser. It will potentially employ advanced weaponry and an all-electric Integrated Power System. Integrated Power System The Royal Navy's first destroyers were the Havock-class destroyers of 1893. The Royal Navy currently operates 8 ships of the Type 42 class. The destroyers (as well as frigates) are, as always, the workhorses of the fleet, the former optimised for air defence and the latter for surface and subsurface warfare. They are equally at home in large task groups or on independent operations which may include sanctions enforcement, humanitarian relief or anti-drug patrols. British destroyers (of recent times) have an average displacement of around 5,000 tonnes, and are armed with a mixture of guns and missiles including 114 mm (4.5 inch) Mk 8 guns, Sea Dart Missiles, 20 mm Close range guns, Vulcan Phalanx close in weapons system (CIWS), anti submarine torpedo tubes. The current Royal Navy destroyers are to be replaced by the new Type 45 Daring Class from 2006 onwards. A class of 12 ships is envisaged, with an entire programme budget of £6 billion. Displacing around 7,200 tons, they will be equipped with the UK variant of the Principal Anti-Air Missile System (PAAMS). Design and construction of the first ships is to be split between BAE Systems and Vosper Thornycroft under the overall project management of BAE systems. Two of the ships will be assembled at Scotstoun, by BAE Systems and the other by Vosper Thornycroft at a new shipbuilding facility at Portsmouth Naval Yard.

World War II

, and the use of new, extremely devastating weapons such as the atom bomb. From top going counterclockwise: Allied landing on D-Day 1944, the Nuremberg Rally 1936, the Nagasaki atom bomb 1945, the Soviet flag over the Reichstag in Berlin 1945 and the Gate of Auschwitz.]] World War II, also known as the Second World War, was a mid-20th Century conflict that engulfed much of the globe and is accepted as the largest and deadliest continuous war in human history. It was the first time that a number of newly developed technologies, including nuclear weapons, were used against either military or civilian targets. World War II resulted in the direct or indirect death of anywhere from 50 to 60 million or more people, over 3% of the world population at that time. It is estimated to have cost more money and resources than all other wars combined: about 1 trillion US dollars in 1945 (adjusted for inflation; roughly 10.5 trillion in 2005), not including subsequent reconstruction [http://www.historychannel.com/worldwartwo/?page=triumph5]. The outcomes of the war, including new technology and changes to the world's geopolitical, cultural and economic arrangement, were unprecedented. The conflict began by most Western accounts on September 1 1939 with the German invasion of Poland (the Pacific war is taken to have started on July 7 1937 with the Japanese attack on China) and lasted until mid-1945, involving many of the world's countries. Virtually all countries that participated in World War I were involved in World War II. Britain, France, Australia and New Zealand declared war on Germany on September 3, 1939 and Canada followed on September 10, 1939. The United States entered the conflict in December of 1941 after the Japanese attack on Pearl Harbor.

Summary

Attributed in varying degrees to the Treaty of Versailles, the Great Depression, and the rise in nationalism, racism, fascism, National socialism, Japanese imperialism, and militarism, the causes of the war are a matter of debate. The war was fought between the Axis Powers and the Allies. The Axis initially consisted of an alliance between Germany and Italy, which later expanded to include Japan and Eastern European countries such as Romania and Bulgaria. Some of the nations that Germany conquered sent military forces, particularly to the Eastern front. Among the expeditionary forces that joined Germany were forces from Vichy France, The Netherlands, Belgium, Spain (though Spain was itself a neutral country) and armies of Russians and Ukrainians under the command of the general Andrey Vlasov. The Allies were initially the United Kingdom, including the Commonwealth, France and Poland, later joined by the USSR, the United States of America and China. Fighting occurred across the Atlantic Ocean, in Western and Eastern Europe, in the Mediterranean Sea, Africa, the Middle East, in the Pacific and South East Asia, and it continued in China. In Europe, the war ended with the surrender of Germany on 8 May 1945 (V-E and Victory Days), but continued in Asia until Japan surrendered on 15 August 1945 (V-J Day). At least 50 million people died as a result of the war. This figure includes acts of genocide such as the Holocaust and General Ishii Shiro's Unit 731 experiments in Pingfan, incredibly bloody battles in Europe and the Pacific Ocean, and massive bombings of cities, including the atomic bombings of Hiroshima and Nagasaki in Japan and the firebombing of Dresden (and even worse but less known) of Pforzheim in Germany. Few areas of the world were unaffected; the war involved the "home front" and bombing of civilians to a new degree. Atomic weapons, jet aircraft, rockets and radar, the blitzkrieg, or "lightning war", the massive use of tanks, submarines, torpedo bombers and destroyer/tanker formations, are only a few of many wartime inventions and new tactics that changed the face of the conflict. Post–World War II Europe was partitioned into Western and Soviet spheres of influence, the former undergoing economic reconstruction under the Marshall Plan and the latter becoming satellite states of the Soviet Union. This partition was, however, informal; rather than coming to terms about the spheres of influence, the relationship between the victors steadily deteriorated, and the military lines of demarcation finally became the de facto country boundaries. Western Europe largely aligned as NATO, and Eastern Europe largely as the Warsaw pact countries, alliances which were fundamental to the ensuing Cold War. In Asia, the United States' military occupation of Japan led to Japan's democratisation. China's civil war continued through and after the war, resulting eventually in the establishment of the People's Republic of China. The war sparked a wave of independence for colonies of European powers, who were exhausted from fighting the war. There was a fundamental shift in power from Western Europe to the new superpowers, the United States and the Soviet Union, though there were few actual boundary changes. __TOC__

Causes

People's Republic of China]] Main articles: Causes of World War II, Events preceding World War II in Europe, Events preceding World War II in Asia The causes of World War II are naturally a debated subject, but a common view, particularly among the allies in the early post-war years, ties them to the expansionism of Germany and Japan: Germany had lost wealth, power and status following the First World War and the expansion was to make Germany great again.
- In Germany there was a strong desire to escape the bonds of the World War I Treaty of Versailles, and eventually, Hitler and the Nazis assumed control of the country. They led Germany through a chain of events: rearmament, reoccupation of the Rhineland, a merger with Austria (Anschluss), incorporation of Czechoslovakia and finally the invasion of Poland.
- In Asia, Japan's efforts to become a world power and the rise of militarist leadership (in the 1930s the government in Japan was undermined as militarists rose to power and de facto gained totalitarian control) led to conflicts with first China and later the United States. Japan also sought to secure additional natural resources, such as oil and iron ore, due in part to the lack of natural resources on Japan's own home islands.

Participants

iron ore and Joseph Stalin, during the Yalta Conference in 1945]] Main article: Participants in World War II The belligerents of the Second World War are usually considered to belong to either of the two blocs: the Axis and the Allies. A number of smaller countries participated in the war, though often under occupation or as proxies of one of the large powers. The Axis Powers consisted primarily of Germany, Italy, and Japan, which split the Earth into three spheres of influence under the Tripartite Pact of 1940, and vowed to defend one another against aggression. This replaced the German-Japanese Anti-Comintern Pact of 1936 that Italy had joined in 1937. Spain's fascist government led by Francisco Franco was a great asset in trade to the Axis powers during the war. A number of smaller countries were counted among the Axis powers. Among these were Bulgaria, Romania, Hungary, Slovenia, and arguably Finland. Among the Allied powers, the so-called Big Three were the United Kingdom (from September 3 1939), the Soviet Union (from June 1941) and the United States (from December 1941). China had been at war with Japan since 1937. 1937 On August 23, 1939, just before the war broke out, the USSR and Germany signed the non-aggression Molotov-Ribbentrop Pact, which, among other things, divided Eastern Europe into regions of influence. But Germany violated the pact when it invaded the USSR in 1941. Similarly, the US had the (much older) unilateral Monroe Doctrine, which stated that Europe should not interfere in the Americas and in turn the U.S. would not interfere in European affairs (including wars). But the U.S. entered the war after first Japan and then Germany declared war on it and launched direct attacks on its navy, shipping and other interests. Many other countries, including Australia, Belgium, Brazil, Canada, Denmark, France, Greece, the Netherlands, New Zealand, Norway, the Philippines, Poland, Thailand and Yugoslavia are also considered important Allies, although some of these were conquered and occupied by Axis forces or even officially joined the Axis as a result of coercion. Countries that attempted to remain neutral in the conflict were often viewed with suspicion by the participants, and often pressured to make contributions to the most influential power in their neighbourhood. Sovereignty was often difficult to maintain as many countries that did not directly participate in the conflict nevertheless held vested interests in seeing a particular side prevail. For example, neutral Switzerland was generally considered to be "Allied-friendly", while neutral Spain was considered "Axis-friendly", despite the fact that neither country openly proclaimed any alliances. Such situations allowed neutral countries to become hotbeds of espionage. It is important to note as well, that Sweden's participation in the war was negligable due to specific relations with the German state at the time.

A debated starting date

On which date World War II started is a debated subject; historians do not all agree on which event signified the start of the war. The most common date used is 1 September 1939, marking the German invasion of Poland which resulted in the British and French declarations of war two days later. Other candidates include the Japanese invasion of China on 7 July1937 (the start of the Second Sino-Japanese War) or the entry of Hitler's armies to Prague in March 1939. Some historians argue that the Italian occupation of Ethiopia (The Second Italo-Abyssinian War) which lasted seven months in 1935-1936 was the actual start of World War II. There are some historians that argue the war started on the start of the Manchurian Incident on 18 September 1931.

1937: Second Sino-Japanese War

On 7 July 1937, Japan, after occupying northeastern China as Manchuria in 1931, launched another attack against China near Beijing (see Marco Polo Bridge Incident). Rather than retreating swiftly as in engagements with the Japanese before, the Chinese government declared war on Japan, marking the official start of the Second Sino-Japanese War, which would soon become part of the World War. In December 1937, the capital, Nanking (now Nanjing), fell and the Chinese government moved its seat to Chongqing for the rest of the war. Surprised by the unanticipated level of resistance from China, the Japanese forces committed brutal atrocities against civilians and POWs when Nanking was occupied (see Nanjing Massacre), killing up to 200,000 civilians within a month. In Europe, the peace was uneasy, with Germany annexing Austria and Czechoslovakia, and taking apparent aim at Poland.

1939: War breaks out in Europe

Poland]] Main articles: Polish September Campaign, Phony War War broke out in Poland on 1 September 1939, with the German invasion of Poland. France and the United Kingdom honoured their defensive alliance of March 1939 by declaring war two days later on 3 September. Australia and New Zealand declared war the same day, although through the quirk of the international date line, New Zealand then Australia were the first to declare war on Germany. Canada followed a week later, on 10 September. Only partly mobilised and with troops inadequately equipped with largely outdated weapons (which included large numbers of horse-mounted cavalry), and without the anticipated support of French or British forces, Poland unsurprisingly fared poorly against the Wehrmacht's superior numbers and "blitzkrieg" tactics. In accordance with the Molotov-Ribbentrop Pact, the Soviet Red Army invaded Poland from the east on 17 September. Hours later, the Polish government escaped to Romania. The last Polish Army unit was defeated on 6 October. As Poland fell, the British and French were either caught unaware of German intentions or had not allowed themselves to believe that Germany would invade Poland. Germany paused to regroup during a period that would be termed "the Phony War", or the "Sitzkrieg", which lasted until May 1940. Polish forces continued to fight the Axis powers after their country fell. A prominent example was the assistance of Polish pilots during the Battle of Britain. The Soviet Union, due to its treaty relationship with Nazi Germany, did not fight the fascists: Stalin was happy to have those he felt were his natural and true enemies—the capitalist West and Nazi Germany—fight each other. Indeed, the Soviets had their partisans in the U.S., working alongside Nazi sympathisers, advocate that the U.S. remain neutral in the war, a position that the majority of Americans, reluctant to join in what they saw as "someone else's war," welcomed. Battle of Britain There were isolated engagements during the "Phony War" or "Sitzkrieg" period, including the sinking of HMS Royal Oak in the anchorage at Scapa Flow and Luftwaffe bombings of the naval bases at Rosyth and Scapa Flow. The Kriegsmarine pocket battleship Admiral Graf Spee was sunk in South America after the battle of the River Plate. The Tripartite Pact was signed between Germany, Italy, and Japan on 27 September, 1940, formalising their alignment as the "Axis Powers". The Soviet Union invaded Finland on 30 November 1939, beginning the Winter War, which lasted until March 1940 with Finland ceding territory to the Soviet Union.

1940: The war spreads

Winter War Main Articles: Norwegian Campaign, Battle of France, Battle of Britain, North African Campaign, Balkans Campaign Europe: Germany invaded Denmark and Norway on 9 April 1940, in Operation Weserübung, ostensibly to counter the threat of an Allied invasion from the region. Heavy fighting ensued on land and at sea in Norway. British, French and Polish forces landed to support the Norwegians at Namsos, Åndalsnes and Narvik, with most success at the latter. By late June, all Allied forces had been evacuated, and the Norwegian Army surrendered. France, Belgium, the Netherlands and Luxembourg were invaded on 10 May, ending the Phony War and beginning the Battle of France. The Allies had hoped to establish a static continuous front and were ill-prepared for the German Blitzkrieg tactics. In the first phase of the invasion, Operation Yellow, the Wehrmacht's Panzergruppe von Kleist bypassed the Maginot Line and split the Allies in two by driving to the English Channel. Belgium, Luxembourg, and the Netherlands fell quickly against the attack of Army Group B, and the British Expeditionary Force, trapped in the north, was evacuated at Dunkirk in Operation Dynamo. German forces then invaded France itself, in Operation Red, advancing behind the Maginot Line and near the coast. While some units from the French army were still fighting, a number of top politicians and military leaders decided that it would be better to surrender given the situation; France signed an armistice with Germany on June 22 1940, leading to the establishment of the Vichy France puppet government in the unoccupied part of France. In June 1940 the Soviet Union occupied Latvia, Lithuania and Estonia, and annexed Bessarabia and Northern Bukovina from Romania. Not having secured a rapid peace with the United Kingdom, Germany began preparations to invade with the Battle of Britain. Fighter aircraft fought overhead for months as the Luftwaffe and Royal Air Force fought for control of Britain's skies. The Luftwaffe initially targeted RAF Fighter Command but turned to terror bombing London. The Luftwaffe was not successful, and Operation Sealion, the proposed invasion of the British Isles, was abandoned. Similar efforts were made, though at sea, in the Battle of the Atlantic. In a long-running campaign, German U-Boats attempted to deprive the British Isles of necessary Lend Lease cargo from the United States. The U-Boats reduced shipments considerably; however, the United Kingdom refused to seek peace, with Prime Minister Winston Churchill stating that "We shall never surrender". President Roosevelt announced a shift in the American stance from neutrality to "non-belligerency". The Mediterranean: Italy invaded Greece on 28 October 1940, from bases in Albania. Although outnumbered, Greek forces successfully repelled the Italian attacks and launched a full-scale counter-attack deep into Albania. By mid-December they had liberated one-fourth of Albania. The North African Campaign began in 1940; Italian forces in Libya attacked British forces in Egypt. The aim was to make Egypt an Italian possession, especially the vital Suez Canal. British, Indian and Australian forces counter-attacked (see Operation Compass), but this offensive stopped in 1941 when much of the Commonwealth forces were transferred to Greece to defend it from German attack. However, German forces (known later as the Afrika Korps) under General Erwin Rommel landed in Libya and renewed the assault on Egypt. Italian troops invaded and captured British Somaliland in August 1940. On the other hand, the Italian declaration of war challenged the British supremacy of this sea, a supremacy hinged on Gibraltar, Malta and Alexandria. While Gibraltar was never under direct attack, Alexandria and to a deadlier degree Malta were hit repetitively by Axis attacks, the thrusts towards the Suez Canal for the former, and the 1940/42 Blitz for the latter, which made the island of Malta the most heavily bombed place on earth. Asia: In 1940, Japan occupied French Indochina (Vietnam) upon agreement with the Vichy Government, despite local Free French, and joined Axis powers Germany and Italy. These actions intensified Japan's conflict with the United States and the United Kingdom, which reacted with an oil boycott.

1941: The war becomes global

Main articles: Eastern Front, Continuation War, Attack on Pearl Harbor Europe: Attack on Pearl Harbor Yugoslavia's government succumbed to the pressure of Italy and Germany and signed the Tripartite Treaty on 25 March 1941. This was followed by anti-Axis demonstrations in the country and a coup which overthrew the government and replaced it with a pro-Allied one on 27 March 1941. Hitler's forces then invaded Greece and Yugoslavia on 6 April 1941. Hitler reluctantly sent forces to assist Mussolini's forces in their attempt to capture Greece, principally to prevent a British build-up on Germany's strategic southern flank. With these new troops the Axis succeeded in driving the Greek forces back. British troops were diverted from North Africa to assist with the defence but failed to prevent Greece's capture. On 20 May 1941, the Battle of Crete began when elite German paratroopers and glider-borne mountain troops and some 1300 aeroplanes launched a massive airborne invasion of the Greek island of Crete. Crete was defended by an group of about 43,000 Greek, New Zealand, Australian and British troops, not all of them fully equipped. The Germans attacked the island simultaneously on the three airfields. Their invasion on two of the airfields failed, but they successfully captured one, which allowed them to reinforce their position by landing reinforcements. After a week it was decided that so many German troops had been flown in that there was no way to defeat them, and about 17,000 Commonwealth soldiers were evacuated. However, over 10,000 Greek and 500 Commonwealth troops remained at large and caused problems for the German occupiers. The Germans may have suffered well over 15,000 casualties. So heavy were the losses that Hiler decided never to launch an airborne invasion again. General Kurt Student would later say, "Crete was the grave of the German parachutists". The Allies, on the other hand, came to the conclusion that every major invasion should be supported by paratroopers. Operation Barbarossa, the German invasion of the Soviet Union, the largest invasion in history, commenced on 22 June 1941. The "Great Patriotic War" (Russian: Великая Отечественная Война, Velikaya Otechestvennaya Voyna) had begun with surprise attacks by German panzer armies, which encircled and destroyed much of the Soviet's western military, capturing or killing hundreds of thousands of men. Soviet forces came to fight a war of scorched earth, withdrawing into the steppe of Russia to acquire time and stretch the German army. Industries were dismantled and withdrawn to the Ural mountains for reassembly. German armies pursued a three-pronged advance against Leningrad (modern-day St Petersburg), Moscow, and the Caucasus. Having pushed to occupy Moscow before winter, German forces were delayed into the Soviet Winter. Soviet counter-attacks defeated them within sight of Moscow's spires, and a rout was only narrowly avoided. Some historians identify this as the "turning point" in the Allies' war against Germany; others identify the capitulation of the German Sixth Army outside Stalingrad (modern-day Volgograd) in 1943. The Continuation War between Finland and the Soviet Union began with Soviet air attacks shortly after the beginning of Operation Barbarossa, on 25 June, and ended with an armistice in 1944. The Soviet Union was joined in the war by the United Kingdom but not by the United States. The Mediterranean again: In June 1941, Allied forces invaded Syria and Lebanon, capturing Damascus on 17 June (see Syria-Lebanon campaign). Meanwhile, Rommel's forces advanced rapidly eastward, laying siege to the vital seaport of Tobruk. Australian and other Allied troops in the city resisted all until relieved, but a renewed Axis offensive captured the city and drove the Eighth Army back to a line at El Alamein. Asia: The Sino-Japanese War El Alamein Main article: Sino-Japanese War (1937-1945) A war had begun in Asia years before World War II started in Europe. Japan had invaded China in 1931. By 1937, war had broken out as the Japanese sought control of China. Roosevelt signed an unpublished (secret) executive order in May 1940 allowing U.S. military personnel to resign from the service so that they could participate in a covert operation in China: the American Volunteer Group, also known as Chennault's Flying Tigers. Over a seven-month period, Chennault's Flying Tigers destroyed an estimated 600 Japanese aircraft, sunk numerous Japanese ships, and stalled the Japanese invasion of Burma. With the United States and other countries cutting exports to Japan, particularly fuel oil, Japan planned a strike on Pearl Harbor on Sunday, 7 December 1941, to cripple the U.S. Pacific Fleet while consolidating oil fields in Southeast Asia. It is hard to determine whether the Japanese intended to release an advance declaration of war, however, as means of coordinating secret directives with public communication, particularly during a weekend in the U.S., were limited. Despite what warning signs remained, the attack on Pearl Harbor achieved military surprise and dealt severe damage to the American Fleet's battleships, though the primary targets, aircraft carriers, remained safely at sea. The next day, Japanese forces arrived at Hong Kong, which later led to the surrender of the British colony on Christmas Day (known to locals as 'Black Christmas'), as well as launching numerous attacks on British and American outposts across the Pacific. Asia: The United States enters the war
Main article: Attack on Pearl Harbor Attack on Pearl Harbor On 7 December 1941, Japanese warplanes commanded by Vice Admiral Chuichi Nagumo carried out a surprise air raid on Pearl Harbor, the largest U.S. naval base in the Pacific. The Japanese forces met little resistance and devastated the harbour. This attack resulted in 8 battleships either sunk or damaged, 3 light cruisers and 3 destroyers sunk as well as damage to some auxiliaries and 343 aircraft either damaged or destroyed. However the attack failed to strike targets that could have been crippling losses to the US Pacific Fleet such as the aircraft carriers which were out at sea at the time of the attack or the base's ship fuel storage and repair facilities. The survival of these assets have led many to consider this attack a catastrophic long term strategic blunder for Japan. The following day, the United States declared war on Japan. Simultaneo
