United States Navy

The United States Navy (USN) is the naval warfare service branch of the United States Armed Forces and one of the seven uniformed services of the United States. It is the largest navy in the world, with a battle fleet tonnage that is greater than that of the next 13 largest navies combined.[4] The U.S. Navy also has the world's largest carrier fleet, with 11 in service, one under construction (two planned), and one in reserve. The service has 321,053 personnel on active duty and 106,188 in the Navy Reserve. It operates 286 ships in active service and more than 3,700 aircraft.[2]

The Navy traces its origins to the Continental Navy, which was established during the American Revolutionary War and was essentially disbanded as a separate entity shortly thereafter. The United States Constitution provided the legal basis for a military force by giving Congress the power "to provide and maintain a navy".[5]

Depredations against U.S. shipping by Barbary Coast pirates in the Mediterranean Sea spurred Congress to employ this power by passing the Naval Act of 1794 ordering the construction and manning of six frigates.[6] These ships were used to end most pirate activity off the Barbary Coast. In the 20th century, American blue-water navy capability was demonstrated by the 1907–1909 world tour of the Great White Fleet.

The 21st century United States Navy maintains a sizable global presence, deploying in such areas as East Asia, the Mediterranean, and the Middle East. It is a blue-water navy with the ability to project force onto the littoral regions of the world, engage in forward areas during peacetime, and rapidly respond to regional crises, making it an active player in U.S. foreign and defense policy.

The Navy is administratively managed by the Department of the Navy, which is headed by the civilian Secretary of the Navy. The Department of the Navy is itself a division of the Department of Defense, which is headed by the Secretary of Defense. Traditionally, the highest ranking naval officer (O-10 on the pay chart) is the Chief of Naval Operations, a position currently held by Admiral Jonathan Greenert, however one naval officer currently outranks him. The highest ranking naval officer is the Vice Chairman of the Joint Chiefs of Staff, Admiral [http://en.wikipedia.org/wiki/James_A._Winnefeld,_Jr. James Winnefeld].

[edit] Mission
The mission of the Navy is to maintain, train and equip combat-ready Naval forces capable of winning wars, deterring aggression and maintaining freedom of the seas.—Mission statement of the United States Navy[7] From the New Recruits Handbook: The mission of the United States Navy is to protect and defend the right of the United States and our allies to move freely on the oceans and to protect our country against her enemies.The United States Navy serves as a seaborne branch of the Military of the United States. 10 U.S.C. § 5062 prescribes the Navy's three primary areas of responsibility: U.S. Navy training manuals state the mission of the U.S armed forces is "to prepare and conduct prompt and sustained combat operations in support of the national interest". As part of that establishment, the U.S. Navy's functions comprise sea control, power projection and nuclear deterrence, in addition to "sealift" duties.[8]
 * "The preparation of naval forces necessary for the effective prosecution of war"
 * "The maintenance of naval aviation, including land-based naval aviation, air transport essential for naval operations and all air weapons and air techniques involved in the operations and activities of the Navy"
 * "The development of aircraft, weapons, tactics, technique, organization, and equipment of naval combat and service elements".

[edit] History
Main article: History of the United States Navy===[edit] Origins=== It follows then as certain as that night succeeds the day, that without a decisive naval force we can do nothing definitive, and with it, everything honorable and glorious.—George Washington[9] In the early stages of the American Revolutionary War, the establishment of an official navy was an issue of debate among the members of the Continental Congress. Supporters argued that a navy would protect shipping, defend the coast, and make it easier to seek out support from foreign countries. Detractors countered that challenging the British Royal Navy, then the world's preeminent naval power, was a foolish undertaking.[6]

Commander in Chief George Washington commissioned seven ocean-going cruisers to interdict British supply ships, and reported the captures to the Congress. This effectively ended the debate in Congress as to whether or not to "provoke" the British by establishing a Navy as Washington's ships had already captured British ships, somewhat a provocation.

While Congress deliberated, it received word that two unarmed British supply ships from England were heading towards Quebec without escort. A plan was drawn up to intercept the ships—however, the armed vessels to be used were owned not by Congress, but by individual colonies. Of greater significance then was an additional plan to equip two ships that would operate under the direct authority of Congress to capture British supply ships. This was not carried out until 13 October 1775, when George Washington announced that he had taken command of three armed schooners under Continental authority to intercept any British supply ships near Massachusetts. With the revelation that vessels were already sailing under Continental control, the decision to add two more was made easier;[10] the resolution was adopted and 13 October would later become known as the U.S. Navy's official birthday.[11]

The Continental Navy achieved mixed results; it was successful in a number of engagements and raided many British merchant vessels, but it lost 24 of its vessels[12] and at one point was reduced to two in active service.[13] As Congress turned its attention after the conflict towards securing the western border of the new United States, a standing navy was considered to be dispensable because of its high operating costs and its limited number of roles.[6]

[edit] From reestablishment to the Civil War
We ought to begin a naval power, if we mean to carry on our commerce.—Thomas Jefferson[14] The United States would be without a navy for nearly a decade—a state of affairs that exposed its merchant ships to a series of attacks by Barbary pirates. The sole armed maritime presence between 1790 and the launching of the U.S. Navy's first warships in 1797 was the U.S. Revenue Cutter Service (USRCS), the primary predecessor of the U.S. Coast Guard. Although USRCS Cutters conducted operations against these pirates, the depredations far outstripped the abilities of the USRCS and Congress ordered the construction and manning of six frigates on 27 March 1794;[12] three years later the first three were welcomed into service: the USS United States, USS Constellation and USS Constitution. USS Constitution battles HMS Guerriere in the War of 1812.Following an undeclared Quasi-War with France, the U.S. Navy saw substantial action in the War of 1812, where it was victorious in numerous single-ship duels with the Royal Navy. The Navy drove all significant British forces off of Lake Erie and Lake Champlain and prevented them from becoming British controlled zones of conflict. Despite this, the U.S. Navy was unable to prevent the British from blockading American ports and landing troops on American soil.[6] After the war, the U.S. Navy again focused its attention on protecting American shipping assets, sending squadrons to the Caribbean, the Mediterranean, South America, Africa, and the Pacific.<sup class="reference" id="cite_ref-love_11-2">[12]

During the Mexican-American War the U.S. Navy contributed by instituting blockades of Mexican ports, capturing or burning the Mexican fleet in the Gulf of California and capturing all major cities in Baja California peninsula—later returned. In 1846-1848 the navy successfully used the Pacific Squadron under Commodore (Rear Admiral) Robert Stockton and its marines and blue-jackets to facilitate the capture of California with large scale land operations coordinated with the local militia organized in the California Battalion. The navy conducted the U.S. military's first large-scale amphibious joint operation by successfully landing 12,000 army troops with their equipment in one day at Veracruz, Mexico. When larger guns were needed to bombard Veracruz Navy volunteers landed large navy guns and manned them in the successful bombardment of the city and its surrender. This successful landing and capture of Veracruz eventually opening the way for the capture of Mexico City and the end of the war.<sup class="reference" id="cite_ref-multiple1_5-4">[6] The United States Navy established itself as a player in American foreign policy through the actions of Commodore Matthew Perry in Japan, which resulted in the Convention of Kanagawa in 1854.

Naval power would play a significant role during the American Civil War, where the Union had a distinct advantage over the Confederacy on the seas.<sup class="reference" id="cite_ref-multiple1_5-5">[6] A Union blockade on shipping handicapped the Southern effort throughout the conflict. The two American navies would help usher in a new era in world naval history by putting ironclad warships into combat for the first time. The Battle of Hampton Roads in 1862, which pitted USS Monitor against CSS Virginia, became the first engagement between two steam-powered ironclads.<sup class="reference" id="cite_ref-howarth_12-1">[13] Soon after the war, however, the U.S. Navy's fleet slipped into obsolescence because of neglect.

[edit] 20th century
The Great White Fleet demonstrates U.S. naval power in 1907; it was proof that the US Navy had blue-water capability.Our ships are our natural bulwarks.—Woodrow Wilson<sup class="reference" id="cite_ref-FamousNavyQuotes_8-1">[9] A modernization program beginning in the 1880s with the first steel hulled warships stimulated the American steel industry and "the new steel navy" was born.<sup class="reference" id="cite_ref-14">[15] This rapid expansion of the US Navy and its easy victory over the Spanish Navy in 1898 brought a new respect for American technical quality. Rapid building of at first pre-dreadnoughts, then dreadnoughts brought the U.S. in line with the navies of countries such as Britain and Germany. In 1907, most of the Navy's battleships, with several support vessels, dubbed the Great White Fleet, were showcased in a 14-month circumnavigation of the world. Ordered by President Theodore Roosevelt, it was a mission designed to demonstrate the Navy's capability to extend to the global theater.<sup class="reference" id="cite_ref-love_11-3">[12] By 1911, the US had begun building the super-dreadnoughts at a pace to eventually become competitive with even Britain.<sup class="reference" id="cite_ref-15">[16] Columbia, personification of the United States, wearing a warship bearing the words "World Power" as her "Easter bonnet" on the cover of Puck, April 6, 1901.The Navy saw little action during World War I, but nevertheless the strength of the United States Navy grew under an ambitious ship building program associated with the Naval Act of 1916. Naval construction, especially of battleships was later limited by the Washington Naval Conference of 1921-22. Saratoga and Lexington were built on the hulls of partially built battle cruisers that had been canceled by the treaty. Construction of aircraft carriers continued however, accelerating after the New Deal, which provided funding for the construction of the USS Yorktown (CV-5) and USS Enterprise (CV-6). These ships would not have been built had it not been for the demonstrations of the capability of aircraft against ships by Gen Billy Mitchell. By 1936, with the completion of the USS Wasp (CV-7), the U.S. Navy possessed a carrier fleet of 165,000 tonnes displacement, although this figure was nominally recorded as 135,000 tonnes to comply with treaty limitations.

[edit] World War II
Main article: United States Navy in World War IIA recruitment poster from 1917, emphasizing the U.S. Navy's transport functionThe U.S. Navy grew into a formidable force in the years prior to World War II, with battleship production being restarted in 1937, commencing with the USS North Carolina (BB-55). Though ultimately unsuccessful, Japan attempted to allay this strategic threat with the 1941 surprise attack on Pearl Harbor. Following American entry into the war, the U.S. Navy grew tremendously as the United States was faced with a two-front war on the seas. It achieved notable acclaim in the Pacific Theater, where it was instrumental to the Allies' successful "island hopping" campaign.<sup class="reference" id="cite_ref-howarth_12-2">[13] The U.S. Navy participated in many significant battles, including the Battle of the Coral Sea, the Battle of Midway, the Solomon Islands Campaign, the Battle of the Philippine Sea, the Battle of Leyte Gulf, and the Battle of Okinawa. By 1943, the Navy's size was larger than the combined fleets of all the other combatant nations in World War II.<sup class="reference" id="cite_ref-Tread_16-0">[17] By war's end in 1945, the United States Navy had added hundreds of new ships, including 18 aircraft carriers and 8 battleships, and had over 70% of the world's total numbers and total tonnage of naval vessels of 1,000 tons or greater.<sup class="reference" id="cite_ref-Defense_Analysis.3B_Dec_2001.2C_Vol._17_Issue_3.2C_p259-265_17-0">[18] <sup class="reference" id="cite_ref-18">[19] At its peak, the U.S. Navy was operating 6,768 ships on V-J Day in August 1945.<sup class="reference" id="cite_ref-19">[20]

Doctrine had significantly shifted by the end of the war. The United States Navy had followed in the footsteps of the navies of Great Britain and Germany which favored concentrated groups of battleships as their main offensive naval weapons.<sup class="reference" id="cite_ref-20">[21] The development of the aircraft carrier and its devastating utilization by the Japanese against the U.S. at Pearl Harbor however shifted U.S. thinking. The Pearl Harbor attack destroyed or took out of action a significant number of U.S.N. battleships. This placed much of the burden of retaliating against the Japanese on the small number of aircraft carriers.<sup class="reference" id="cite_ref-21">[22]

[edit] Cold War
The potential for armed conflict with the Soviet Union during the Cold War pushed the U.S. Navy to continue its technological advancement by developing new weapons systems, ships, and aircraft. United States naval strategy changed to that of forward deployment in support of U.S. allies with an emphasis on carrier battle groups.<sup class="reference" id="cite_ref-22">[23]

The Navy was a major participant in the Vietnam War, blockaded Cuba during the Cuban Missile Crisis, and, through the use of ballistic missile submarines, became an important aspect of the United States' nuclear strategic deterrence policy. The United States Navy conducted various combat operations in the Persian Gulf against Iran in 1987 and 1988, most notably Operation Praying Mantis. The Navy was extensively involved in Operation Urgent Fury, Operation Desert Shield, Operation Desert Storm, Operation Deliberate Force, Operation Allied Force, Operation Desert Fox and Operation Southern Watch.

The U.S. Navy has also been involved in Search and Rescue/Search and Salvage operations, some times in conjunction with vessels of other countries as well as with U.S. Coast Guard ships. Two examples are the 1966 Palomares B-52 crash incident and search for the nuclear bombs, and the Task Force 71 of the Seventh Fleet operation in search for Korean Air Lines Flight 007 shot down by the Soviets on Sept. 1, 1983.

[edit] 21st century
When a crisis confronts the nation, the first question often asked by policymakers is: 'What naval forces are available and how fast can they be on station?'—Admiral Carlisle A. H. Trost<sup class="reference" id="cite_ref-23">[24] Six modern amphibious assault ships of the US Navy in formationThe United States Navy continues to be a major support to U.S. interests in the 21st century. Since the end of the Cold War, it has shifted its focus from preparations for large-scale war with the Soviet Union to special operations and strike missions in regional conflicts.<sup class="reference" id="cite_ref-forward_24-0">[25] The Navy participated in Operation Enduring Freedom, Operation Iraqi Freedom, and is a major participant in the ongoing War on Terror, largely in this capacity. Development continues on new ships and weapons, including the Gerald R. Ford class aircraft carrier and the Littoral combat ship. Because of its size, weapons technology, and ability to project force far from U.S. shores, the current U.S. Navy remains a potent asset for the United States Commander-in-Chief (the President of the United States).

In 2007, the U.S. Navy joined with the U.S. Marine Corps and U.S. Coast Guard to adopt a new maritime strategy called A Cooperative Strategy for 21st Century Seapower that raises the notion of prevention of war to the same philosophical level as the conduct of war. The strategy was presented by the Chief of Naval Operations, the Commandant of the Marine Corps and Commandant of the Coast Guard at the International Sea power Symposium in Newport, R.I. on 17 October 2007.<sup class="reference" id="cite_ref-25">[26] The strategy recognized the economic links of the global system and how any disruption due to regional crises—man made or natural—can adversely impact the U.S. economy and quality of life. This new strategy charts a course for the Navy, Coast Guard and Marine Corps to work collectively with each other and international partners to prevent these crises from occurring or reacting quickly should one occur to prevent negative impacts on the United States.

During the George W. Bush administration, the fleet dropped to a total number of ships that was smaller than any time since 1917.<sup class="reference" id="cite_ref-26">[27]

In 2010, Chief of Naval Operations, Admiral Gary Roughead noted that demands on the Navy have grown as the fleet has shrunk and that in the face of declining budgets in the future, the US Navy must rely even more on international partnerships.<sup class="reference" id="cite_ref-27">[28]

In its 2013 budget request, the Navy has focused on retaining all eleven big deck carriers, at the expense of cutting numbers of smaller ships and delaying the SSBN replacement.<sup class="reference" id="cite_ref-28">[29]

[edit] Organization
Main article: Structure of the United States NavySimplified flowchart of U.S. Navy command structureThe Navy falls under the administration of the Department of the Navy, under civilian leadership of the Secretary of the Navy (SECNAV). The most senior naval officer is the Chief of Naval Operations (CNO), a four-star admiral who is immediately under and reports to the Secretary of the Navy. At the same time, the Chief of Naval Operations is one of the Joint Chiefs of Staff, which is the second-highest deliberatory body of the armed forces after the United States National Security Council, although it only plays an advisory role to the President and does not nominally form part of the chain of command. The Secretary of the Navy and Chief of Naval Operations are responsible for organizing, recruiting, training, and equipping the Navy so that it is ready for operation under the command of the Unified Combatant Commanders.

[edit] Operating forces
Main article: List of units of the United States NavyThere are nine components in the operating forces of the U.S. Navy: the United States Fleet Forces Command, United States Pacific Fleet, United States Naval Forces Central Command, United States Naval Forces Europe, Naval Network Warfare Command, Navy Reserve, United States Naval Special Warfare Command, Operational Test and Evaluation Force, and Military Sealift Command. Fleet Forces Command controls a number of unique capabilities, including Military Sealift Command, Naval Expeditionary Combat Command, and Navy Cyber Forces.

The United States Navy has six active numbered fleets — Third, Fifth, Sixth, Seventh Fleet and Tenth Fleets are each led by a three-star vice admiral, and the Fourth Fleet is led by a rear admiral. These six fleets are further grouped under Fleet Forces Command (the former Atlantic Fleet), Pacific Fleet, Naval Forces Europe-Africa, and Naval Forces Central Command, whose commander also doubles as Commander Fifth Fleet; the first three commands being led by four-star full admirals. The United States First Fleet existed after the Second World War from 1947, but it was redesignated Third Fleet in early 1973. In early 2008, the Navy reactivated the United States Fourth Fleet to control operations in the area controlled by Southern Command, which consists of US assets in and around Central and South America.<sup class="reference" id="cite_ref-29">[30]

[edit] Shore establishments
USS Kitty Hawk (CV-63) docks at the U.S. Navy base in Yokosuka, Japan.Shore establishments exist to support the mission of the fleet through the use of facilities on land. Among the commands of the shore establishment, as of April 2011, are the Naval Education and Training Command, the Naval Meteorology and Oceanography Command, the Space and Naval Warfare Systems Command, the Naval Facilities Engineering Command, the Naval Supply Systems Command, the Naval Air Systems Command, the Naval Sea Systems Command, the Bureau of Medicine and Surgery, the Bureau of Naval Personnel, the United States Naval Academy, the Naval Safety Center, the Naval Strike and Air Warfare Center, and the United States Naval Observatory.<sup class="reference" id="cite_ref-30">[31] Official Navy websites list the Office of the Chief of Naval Operations and the Chief of Naval Operations (CNO) as part of the shore establishment, but these two entities effectively sit superior to the other organizations, playing a coordinating role.

[edit] United States Marine Corps
A Marine F/A-18 from VMFA-451 prepares to launch from the USS Coral Sea (CV-43)In 1834, the Marines came under the Department of the Navy.<sup class="reference" id="cite_ref-31">[32] Historically, the United States Navy has had a unique relationship with the United States Marine Corps (USMC), partly because they both specialize in seaborne operations. Together the Navy and Marine Corps form the Department of the Navy and report to the Secretary of the Navy. However, the USMC is considered to be a distinct, separate service branch with its own uniformed service chief - the Commandant of the Marine Corps (CMC), a four star general.

The Navy and Marine Corps have a distinct relationship, the USMC depends on the Navy for religious support (i.e. chaplains) and medical support (i.e., dentists, medical doctors, medics known as "Corpsmen" and medical service staff); thus officers and enlisted sailors from the Navy fulfill these roles. When attached to Marine Corps units deployed to an operational environment they generally wear Marine camouflage uniforms, but otherwise they wear Navy dress uniforms unless they opt to conform to USMC grooming standards (appearance).

In the operational environment, as an expeditionary force specializing in amphibious operations, Marines often embark on Navy ships in order to conduct operations from beyond territorial waters. Marine units deploying as part of a Marine Air-Ground Task Force (MAGTF) operate under the command of the existing Marine chain of command. Although Marine units routinely operate from amphibious assault ships the relationship has evolved over the years much as the "CAG" (Commander of the Carrier Air Group/Wing) does not work for the carrier Commanding Officer (CO), but coordinates with the ship's CO and staff. Some Marine aviation squadrons, usually fixed-wing assigned to Carrier Air Wings (CVW) train and operate alongside Navy squadrons, flying similar missions and often flying sorties together under the cognizance of the "CAG". Aviation is where the Navy and Marine share the most common ground, since aircrews are guided in their use of aircraft by standard procedures outlined in series of publications known as NATOPS manuals.

[edit] United States Coast Guard
Main article: United States Coast GuardAlthough the Posse Comitatus Act, which prevents federal military personnel from acting in a law enforcement capacity, applies only to the Army and Air Force, Department of Defense rules effectively require the Navy and Marine Corps to act as if Posse Comitatus did apply, preventing them from enforcing Federal law. The United States Coast Guard fulfills this law enforcement role in naval operations. It provides Law Enforcement Detachments (LEDETs) to Navy vessels, where they perform arrests and other law enforcement duties during Navy boarding and interdiction missions. In times of war, or when directed by the President, the Coast Guard operates as a service in the Navy and is subject to the orders of the Secretary of the Navy until it is transferred back to the Department of Homeland Security.<sup class="reference" id="cite_ref-32">[33] At other times, Coast Guard Port Security Units are sent overseas to guard the security of ports and other assets. The Coast Guard also jointly staffs the Navy's Naval Coastal Warfare Groups and Squadrons (the latter of which were known as Harbor Defense Commands until late-2004), which oversee defense efforts in foreign littoral combat and inshore areas. Additionally, Coast Guard and Navy vessels sometimes operate together in search and rescue operations.

[edit] Personnel
Main article: Personnel of the United States Navy==[edit] Bases== Main article: List of United States Navy installationsMap of Navy bases in the United StatesThe size, complexity, and international presence of the United States Navy require a large number of navy installations to support its operations. While the majority of bases are located inside the United States itself, the Navy maintains a significant number of facilities abroad, either in U.S.-controlled territories or in foreign countries under a Status of Forces Agreement (SOFA).

[edit] Eastern United States
The second largest concentration of installations is in Hampton Roads, Virginia, where the Navy occupies over 36,000 acres (146 km²) of land. Located in Hampton Roads are NS Norfolk, homeport of the Atlantic Fleet, NAS Oceana, a Master Jet Base, Naval Amphibious Base Little Creek, as well as a number of Navy and commercial shipyards that service Navy vessels. Also in Virginia is the Aegis Training and Readiness Center located at NSA Dahlgren. There is also a Naval base in Charleston, SC. This is home to the Nuclear A-School. The state of Florida is the location of three major bases, Naval Station Mayport, the Navy's fourth largest, in Jacksonville, Florida, Naval Air Station Jacksonville, a Master Air Anti-submarine Warfare base, and Naval Air Station Pensacola, home of the Naval Education and Training Command, the Naval Air Technical Training Center that provides specialty training for enlisted aviation personnel, and the primary flight training base for Navy and Marine Corps Naval Flight Officers and enlisted Naval Aircrewmen. There is also Naval Support Activity in Panama City Beach, Florida which is home to the Navy Diving and Salvage Training Center. The main U.S. Navy submarine bases on the east coast are located in Groton, Connecticut and Kings Bay, Georgia. There are also naval bases in Portsmouth, New Hampshire.<sup class="reference" id="cite_ref-USFacilities_33-0">[34] Naval Station Great Lakes, north of Chicago, Illinois is the home of the navy's boot camp for enlisted sailors.

[edit] Western United States and Hawaii
The Navy's largest complex is China Lake, California, which covers 1.1 million acres (4,500 km²) of land, or approximately 1/3 of the United States Navy's total land holdings.<sup class="reference" id="cite_ref-USFacilities_33-1">[34]

Naval Base San Diego, California is principal home to the Pacific Fleet (although the headquarters is located in Pearl Harbor). NAS North Island is located on the north side of Coronado, and is home to Headquarters for Naval Air Forces and Naval Air Force Pacific, the bulk of the Pacific Fleet's helicopter squadrons, and part of the West Coast aircraft carrier fleet. The Naval Special Warfare Center is the primary training center for SEALs, and is also located on Coronado. The other major collection of naval bases on the west coast is in Puget Sound, Washington. Among them, Naval Station Everett is one of the newer bases and the Navy states that it is its most modern facility.<sup class="reference" id="cite_ref-34">[35] NAS Fallon, Nevada serves as the primary training ground for Navy Strike aircrews, and is home to the Naval Strike Air Warfare Center. Master Jet Bases are also located at NAS Lemoore, California and NAS Whidbey Island, Washington, while the carrier-based airborne early warning aircraft community and major air test activities are located at NAS Point Mugu, California. The naval presence in Hawaii is centered on Pearl Harbor Naval Base, which hosts the headquarters of the Pacific Fleet and many of its subordinate commands.<sup class="reference" id="cite_ref-USFacilities_33-2">[34]

[edit] United States territories
Guam, an island strategically located in the Western Pacific Ocean, maintains a sizable U.S. Navy presence, including Naval Base Guam. The westernmost U.S. territory, it contains a natural deep water harbor capable of harboring even aircraft carriers in emergencies.<sup class="reference" id="cite_ref-35">[36] Its naval air station was deactivated<sup class="reference" id="cite_ref-36">[37] in 1995 and its flight activities transferred to nearby Andersen Air Force Base. Puerto Rico in the Caribbean formerly housed Roosevelt Roads Naval Station, which was shut down in 2004 shortly after the controversial closure of the live ordnance training area on nearby Vieques Island.<sup class="reference" id="cite_ref-USFacilities_33-3">[34]

[edit] Foreign countries
The largest overseas base is in Yokosuka, Japan,<sup class="reference" id="cite_ref-37">[38] which serves as the home port for the Navy's largest forward-deployed fleet and is a significant base of operations in the Western Pacific. European operations revolve around facilities in Italy (Sigonella and Naples), Spain and Greece with Naples as the homeport for the Sixth Fleet and CNRE Command Naval Region Europe, which are based in Gaeta. In the Middle East, naval facilities are located almost exclusively in countries bordering the Persian Gulf, with Manama, Bahrain serving as the headquarters of U.S. Naval Forces Central Command and U.S. Fifth Fleet. Guantánamo Bay in Cuba is the oldest overseas facility and has become known in recent years as the location of a detention camp for suspected al-Qaeda operatives.<sup class="reference" id="cite_ref-ForeignFacilities_38-0">[39]

[edit] Equipment
Main article: Equipment of the United States NavyThe Navy operates 290 ships, 3,700 aircraft, 50,000 non-combat vehicles and owns 75,200 buildings on 3,300,000 acres (13,000 km2). The Navy plans to slash the dependence on fossil fuels.<sup class="reference" id="cite_ref-39">[40]

[edit] Ships
Main article: United States Navy shipsSee also: List of United States Navy ships and List of current ships of the United States NavyThe names of commissioned ships of the U.S. Navy are prefixed with the letters "USS", designating "United States Ship".<sup class="reference" id="cite_ref-40">[41] Non-commissioned, civilian-manned vessels of the Navy have names that begin with "USNS", standing for "United States Naval Ship" The names of ships are officially selected by the Secretary of the Navy, often to honor important people or places. Additionally, each ship is given a letter-based hull classification symbol (for example, CVN or DDG) to indicate the vessel's type and number. All ships in the Navy inventory are placed in the Naval Vessel Register, which is part of "the Navy List" (required by article 29 of the United Nations Convention on the Law of the Sea). The Register tracks data such as the current status of a ship, the date of its commissioning, and the date of its decommissioning. Vessels that are removed from the register prior to disposal are said to be stricken from the register. The Navy also maintains a reserve fleet of inactive vessels that are maintained for reactivation in times of need.

The U.S. Navy was one of the first to install nuclear reactors aboard naval vessels;<sup class="reference" id="cite_ref-41">[42] today, nuclear energy powers all of U.S. active aircraft carriers and submarines. In the case of the Nimitz-class carrier, two naval reactors give the ship almost unlimited range and provide enough electrical energy to power a city of 100,000 people.<sup class="reference" id="cite_ref-42">[43] The U.S. Navy previously operated nuclear-powered cruisers and destroyers, but all have been decommissioned.

The U.S. Navy has identified a need for 313 combat ships, but under the current plans will only be able to afford 232 to 243.<sup class="reference" id="cite_ref-43">[44]

[edit] Aircraft carriers
USS Nimitz (CVN-68), a Nimitz-class aircraft carrierThe Navy has established a minimum requirement for 11 aircraft carriers, but will drop to 10 when the Enterprise retires before the Gerald R. Ford enters service.<sup class="reference" id="cite_ref-44">[45]

A carrier is typically deployed along with a host of additional vessels, forming a carrier strike group. The supporting ships, which usually include three or four Aegis-equipped cruisers and destroyers, a frigate, and two attack submarines, are tasked with protecting the carrier from air, missile, sea, and undersea threats as well as providing additional strike capabilities themselves. Ready logistics support for the group is provided by a combined ammunition, oiler, and supply ship.
 * Enterprise class (1 in commission)
 * Nimitz class (10 in commission)
 * Gerald R. Ford class (1 under construction, at least 2 more planned)

[edit] Amphibious warfare vessels
USS Bataan (LHD-5), a Wasp class amphibious assault shipAmphibious assault ships are the centerpieces of US amphibious warfare and fulfill the same power projection role as aircraft carriers except that their striking force comprises land forces instead of aircraft. They deliver, command, coordinate, and fully support all elements of a 2200-strong Marine Expeditionary Unit in an amphibious assault using both air and amphibious vehicles. Resembling small aircraft carriers, amphibious assault ships are capable of V/STOL, STOVL, VTOL, tiltrotor, and rotary wing aircraft operations. They also contain a well deck to support the use of Landing Craft Air Cushion (LCAC) and other amphibious assault watercraft. Recently, amphibious assault ships have begun to be deployed as the core of an expeditionary strike group, which usually consists of an additional amphibious transport dock and dock landing ship for amphibious warfare and an Aegis-equipped cruiser and destroyer, frigate, and attack submarine for group defense. Amphibious assault ships are typically named after World War II aircraft carriers. Amphibious transport docks are warships that embark, transport, and land Marines, supplies, and equipment in a supporting role during amphibious warfare missions. With a landing platform, amphibious transport docks also have the capability to serve as secondary aviation support for an expeditionary group. All amphibious transport docks can operate helicopters, LCACs, and other conventional amphibious vehicles while the newer San Antonio class of ships has been explicitly designed to operate all three elements of the Marines' "mobility triad": Expeditionary Fighting Vehicles (EFVs), the V-22 Osprey tiltrotor aircraft, and the previously mentioned LCACs. Amphibious transport docks are named for cities, except for USS Mesa Verde (LPD-19), named for Mesa Verde National Park in Colorado, and three San Antonio class ships named in memory of the September 11, 2001 attacks. USS San Antonio (LPD-17), a San Antonio class amphibious transport dock*Austin class (2 in commission, 10 decommissioned) The dock landing ship is a medium amphibious transport that is designed specifically to support and operate Landing Craft Air Cushions (LCACs), though it is able to operate other amphibious assault vehicles in the United States inventory as well. Dock landing ships are normally deployed as a component of an expeditionary strike group's amphibious assault contingent, operating as a secondary launch platform for LCACs. All dock landing ships are named after locations in the United States.

[edit] Surface vessels
USS Port Royal (CG-73), a Ticonderoga class cruiserCruisers are large surface combat vessels that conduct anti-air/anti-missile warfare, surface warfare, anti-submarine warfare, and strike operations independently or as members of a larger task force. Modern guided missile cruisers were developed out of a need to counter the anti-ship missile threat facing the United States Navy. This led to the development of the AN/SPY-1 phased array radar and the Standard missile with the Aegis combat system coordinating the two. Ticonderoga-class cruisers became the first to equip Aegis and were put to use primarily as anti-air and anti-missile defense in a battle force protection role. Later developments of vertical launch systems and the Tomahawk missile gave cruisers additional long-range land and sea strike capability, making them capable of both offensive and defensive battle operations. All cruisers since CG-47 have been named for famous battles with USS Thomas S. Gates (CG-51) as the only exception. Previously, cruisers were either named for cities (until CG-12), former important navy figures (CG-15 to CG-35), or states (CGN-36 to CGN-41). Destroyers are multi-mission medium surface ships capable of sustained performance in anti-air, anti-submarine, anti-ship, and offensive strike operations. Like cruisers, the guided missile destroyers of the Navy are primarily focused on surface strikes using Tomahawk missiles and fleet defense through Aegis and the Standard missile. Destroyers additionally specialize in anti-submarine warfare and are equipped with VLA rockets and LAMPS Mk III Sea Hawk helicopters to deal with underwater threats. When deployed with a carrier strike group or expeditionary strike group, destroyers and their fellow Aegis-equipped cruisers are primarily tasked with defending the fleet while providing secondary strike capabilities. Destroyers have been named for important navy personnel and heroes since the USS Bainbridge (DD-1). USS Bainbridge (DDG-96), an Arleigh Burke-class guided missile destroyerModern U.S. frigates mainly perform anti-submarine warfare for carrier strike groups and amphibious expeditionary groups and provide armed escort for supply convoys and merchant shipping. They are designed to protect friendly ships against hostile submarines in low to medium threat environments, using torpedoes and LAMPS helicopters. Independently, frigates are able to conduct counterdrug missions and other maritime interception operations. The U.S. Navy expects to retire and replace its current class of frigates by 2020 as the Littoral Combat Ships are introduced into operation.<sup class="reference" id="cite_ref-45">[46] As in the case of destroyers, frigates are named after naval heroes.
 * Ticonderoga class (22 in commission, 5 decommissioned)
 * Arleigh Burke class (61 in commission, one awaiting commissioning, one under construction, at least three more planned)
 * Zumwalt class destroyer (3 building or planned)
 * Oliver Hazard Perry class (19 in commission, 8 in active reserve, 24 decommissioned)

[edit] Submarines
Main article: Submarines in the United States NavyUSS Kentucky (SSBN-737), an Ohio class ballistic missile submarineThe primary missions of submarines in the U.S. Navy are peacetime engagement, surveillance and intelligence, special operations, precision strikes, battlegroup operations, and control of the seas.<sup class="reference" id="cite_ref-46">[47] The U.S. Navy operates three types: ballistic submarines, guided missile submarines, and attack submarines. Ballistic missile submarines have only one mission: to carry and launch the nuclear Trident missile. Four Ohio class ballistic missile submarines were converted to guided missile submarines, which have a primary mission of attacking targets on land. Attack submarines have several tactical missions, including sinking ships and other subs, launching cruise missiles, gathering intelligence, and assisting in special operations. Earlier attack submarines (such as the Los Angeles class) are typically named for cities while Ohio class and later attack submarines are typically named for states. Attack submarines prior to the Los Angeles class were named for "denizens of the deep", while pre-Ohio class ballistic missile submarines were named for "famous Americans" (including foreigners with notable connections to the United States).
 * Ohio class ballistic missile submarines (18 in commission, with 4 converted into guided missile submarines)
 * Los Angeles class attack submarines (43 in commission, 2 in reserve, 17 decommissioned)
 * Seawolf class attack submarines (3 in commission)
 * Virginia class attack submarines (9 in commission, 5 under construction, 4 ordered, at least 4 more planned)

[edit] Aircraft
Four Navy F/A-18F Super Hornets.Main articles: List of United States naval aircraft and List of military aircraft of the United States (naval)See also: List of United States Navy aircraft squadronsCarrier-based aircraft are able to strike air, sea, and land targets far from a carrier strike group while protecting friendly forces from enemy aircraft, ships, and submarines. In peacetime, aircraft's ability to project the threat of sustained attack from a mobile platform on the seas gives United States leaders significant diplomatic and crisis-management options. Aircraft additionally provide logistics support to maintain the Navy's readiness and, through helicopters, supply platforms with which to conduct search and rescue, special operations, anti-submarine warfare (ASW), and anti-surface warfare (ASuW).

The U.S. Navy began to research the use of aircraft at sea in the 1910s, with Lt Theodore G. “Spuds” Ellyson becoming the first Naval aviator on 28 January 1911, and commissioned its first aircraft carrier, USS Langley, in 1922.<sup class="reference" id="cite_ref-47">[48] United States naval aviation fully came of age in World War II, when it became clear following the Attack on Pearl Harbor, the Battle of the Coral Sea, and the Battle of Midway that aircraft carriers and the planes that they carried had replaced the battleship as the greatest weapon on the seas. Leading Navy aircraft in World War II included the Grumman F4F Wildcat, the Grumman F6F Hellcat, the Chance Vought F4U Corsair, the Douglas SBD Dauntless, and the Grumman TBF Avenger. Navy aircraft also played a significant role in conflicts during the following Cold War years, with the F-4 Phantom II and the F-14 Tomcat becoming military icons of the era. The Navy's current primary fighter and attack airplanes are the multi-mission F/A-18C/D Hornet and its newer cousin, the F/A-18E/F Super Hornet. The F-35 Lightning II is presently under development and is scheduled to replace the C and D versions of the Hornet beginning in 2012.<sup class="reference" id="cite_ref-48">[49]

The Aircraft Investment Plan sees Naval aviation growing from 30 percent of current aviation forces to half of all procurement funding over the next three decades.<sup class="reference" id="cite_ref-49">[50]

[edit] Weapons
Main article: List of United States Navy weaponsCurrent U.S. Navy shipboard weapons systems are almost entirely focused on missiles, both as a weapon and as a threat. In an offensive role, missiles are intended to strike targets at long distances with accuracy and precision. Because they are unmanned weapons, missiles allow for attacks on heavily defended targets without risk to human pilots. Land strikes are the domain of the BGM-109 Tomahawk, which was first deployed in the 1980s and is continually being updated to increase its capabilities. For anti-ship strikes, the Navy's dedicated missile is the Harpoon missile. To defend against enemy missile attack, the Navy operates a number of systems that are all coordinated by the Aegis combat system. Medium-long range defense is provided by the Standard Missile 2, which has been deployed since the 1980s. The Standard missile doubles as the primary shipboard anti-aircraft weapon and is undergoing development for use in theater ballistic missile defense. Short range defense against missiles is provided by the Phalanx CIWS and the more recently developed RIM-162 Evolved Sea Sparrow Missile. In addition to missiles, the Navy employs Mark 46 and Mark 50 torpedoes and various types of naval mines. Aviation Ordnancemen loading GBU-12 bombs.Naval fixed-wing aircraft employ much of the same weapons as the United States Air Force for both air-to-air and air-to-surface combat. Air engagements are handled by the heat-seeking Sidewinder and the radar guided AMRAAM missiles along with the M61 Vulcan cannon for close range dogfighting. For surface strikes, Navy aircraft utilize a combination of missiles, smart bombs, and dumb bombs. On the list of available missiles are the Maverick, SLAM-ER and JSOW. Smart bombs include the GPS-guided JDAM and the laser-guided Paveway series. Unguided munitions such as dumb bombs and cluster bombs make up the rest of the weapons deployed by fixed-wing aircraft.

Rotary aircraft weapons are focused on anti-submarine warfare (ASW) and light to medium surface engagements. To combat submarines, helicopters use Mark 46 and Mark 50 torpedoes. Against small watercraft, they utilize Hellfire and Penguin air to surface missiles. Helicopters also employ various types of mounted anti-personnel machine guns, including the M60, M240, GAU-16/A, and GAU-17/A.

Nuclear weapons in the U.S. Navy arsenal are deployed through ballistic missile submarines and aircraft. The Ohio-class submarine carries the latest iteration of the Trident missile, a three stage, underwater launched, nuclear ICBM with MIRV capability; the current Trident II (D5) version is expected to be in service past 2020.<sup class="reference" id="cite_ref-50">[51] The Navy's other nuclear weapon is the air-deployed B61 nuclear bomb. The B61 is a thermonuclear device that can be dropped by strike aircraft such as the F/A-18 Hornet and Super Hornet at high speed from a large range of altitudes. It can be released through free-fall or parachute and can be set to detonate in the air or on the ground.

[edit] Naval Jack
Former U.S. Naval JackU.S. Navy country music ensemble performs adjacent to Lone Sailor statueThe current naval jack of the United States is the First Navy Jack, traditionally regarded as having been used during the American Revolutionary War. On 31 May 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 Terror". Many ships chose to shift colors later that year on the first anniversary of the September 11, 2001 attacks. The previous naval jack was a blue field with 50 white stars, identical to the canton of the ensign (the flag of the United States) both in appearance and size, and continues to remain in use with vessels of the U.S. Coast Guard and National Oceanic and Atmospheric Administration. A jack of similar design was used in 1794, though with 13 stars arranged in a 3–2–3–2–3 pattern. When a ship is moored or anchored, the jack is flown from the bow of the ship while the ensign is flown from the stern. When underway, the ensign is raised on the mainmast. The First Naval Jack, however, has always been flown on the oldest ship in the active American fleet, currently the USS Constitution.

[edit] Notable sailors
Main article: List of United States Navy peopleMany past and present United States historical figures have served in the Navy. Notable officers include John Paul Jones, John Barry (Continental Navy officer and first flag officer of the United States Navy),<sup class="reference" id="cite_ref-51">[52] James Lawrence (whose last words "don't give up the ship" are memorialized in Bancroft Hall at the United States Naval Academy), Stephen Decatur, Jr., David Farragut, David Dixon Porter, Oliver Hazard Perry, Commodore Matthew Perry (whose Black Ships forced the opening of Japan), and Chester Nimitz, Admiral of the Pacific Fleet in World War II.

A number of presidents served in the Navy before or early in their political careers, including John F. Kennedy (who commanded the famous PT-109), Lyndon B. Johnson, Richard Nixon, Gerald Ford, Jimmy Carter, and George H.W. Bush. Both Theodore Roosevelt and Franklin D. Roosevelt were the Assistant Secretary of the Navy prior to their presidencies. Many members of Congress served in the Navy, notably U.S. Senators Bob Kerrey, John McCain, and John Kerry. Other notable former members of the U.S. Navy include astronauts, entertainers, authors, and professional athletes.
