By war's end in 1945, the U.S. 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. At its peak, the U.S. Navy was operating 6,768 ships on V-J Day in August 1945. Doctrine had significantly shifted by the end of the war. The U.S. 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. The development of the aircraft carrier and its devastating use 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. Navy battleships. This placed much of the burden of retaliating against the Japanese on the small number of aircraft carriers. During World War II some 4,000,000 Americans served in the United States Navy.

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 U.S. In 2010, Admiral Gary Roughead, Chief of Naval Operations, 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 U.S. Navy must rely even more on international partnerships. In its 2013 budget request, the navy focused on retaining all eleven big deck carriers, at the expense of cutting numbers of smaller ships and delaying the SSBN replacement. By the next year the USN found itself unable to maintain eleven aircraft carriers in the face of the expiration of budget relief offered by the Bipartisan Budget Act of 2013 and CNO Jonathan Greenert said that a ten ship carrier fleet would not be able to sustainably support military requirements.

s unless they opt to conform to Marine Corps grooming standards. In the operational environment, as an expeditionary force specializing in amphibious operations, Marines often embark on Navy ships 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 Commander of the Carrier Air Group/Wing (CAG) does not work for the carrier commanding officer, but coordinates with the ship's CO and staff. Some Marine aviation squadrons, usually fixed-wing assigned to carrier air wings train and operate alongside Navy squadrons; they fly similar missions and often fly sorties together under the cognizance of the CAG. Aviation is where the Navy and Marines share the most common ground since aircrews are guided in their use of aircraft by standard procedures outlined in a series of publications known as NATOPS manuals.

Sailors prove they have mastered skills and deserve responsibilities by completing Personnel Qualification Standards (PQS) tasks and examinations.

Many qualifications are denoted on a sailor's uniform with U.S. Navy badges and insignia.

Commissioned officers

Navy officers serve either as a line officer or as a staff corps officer. Line officers wear an embroidered gold star above their rank of the naval service dress uniform while staff corps officers and commissioned warrant officers wear unique designator insignias that denotes their occupational specialty.


Warrant officers

Warrant and chief warrant officer ranks are held by technical specialists who direct specific activities essential to the proper operation of the ship, which also require commissioned officer authority. Navy warrant officers serve in 30 specialties covering five categories. Warrant officers should not be confused with the limited duty officer (LDO) in the Navy. Warrant officers perform duties that are directly related to their previous enlisted service and specialized training. This allows the Navy to capitalize on the experience of warrant officers without having to frequently transition them to other duty assignments for advancement. Most Navy warrant officers are accessed from the

CMC insignia are similar to the insignia for Master Chief, except that the rating symbol is replaced by an inverted five-point star, reflecting a change in their rating from their previous rating (i.e., MMCM) to CMDCM. The stars for Command Master Chief are silver, while stars for Fleet or Force Master Chief are gold. Additionally, CMCs wear a badge, worn on their left breast pocket, denoting their title (Command/Fleet/Force).

As described in Chapter 5 of U.S. Navy Uniform Regulations, "badges" are categorized as ''breast insignia'' (usually worn immediately above and below ribbons) and ''identification badges'' (usually worn at breast pocket level). Breast insignia are further divided between ''command'' and ''warfare and other qualification''. Insignia come in the form of metal "pin-on devices" worn on formal uniforms and embroidered "tape strips" worn on work uniforms. For the purpose of this article, the general term "insignia" shall be used to describe both, as it is done in Navy Uniform Regulations. The term "badge", although used ambiguously in other military branches and in informal speak to describe any pin, patch, or tab, is exclusive to ''identification badges'' and authorized '' marksmanship awards'' according to the language in Navy Uniform Regulations, Chapter 5.

Equipment

, the navy operates over 460 ships, including vessels operated by the Military Sealift Command (MSC) crewed by a combination of civilian contractors and a small number of uniformed Naval personnel, 3,650+ aircraft, 50,000 non-combat vehicles and owns 75,200 buildings on .


Ships

The names of commissioned ships of the U.S. Navy are prefixed with the letters "USS", designating "United States Ship". 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 The United States Navy, United States Coast Guard, and United States National Oceanic and Atmospheric Administration (NOAA) use a hull classification symbol (sometimes called hull code or hull number) to identify their ships by type and by ...
(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 United States Navy reserve fleets, 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; today, Nuclear power, nuclear energy powers all active U.S. aircraft carriers and submarines. In the case of the carrier, two United States Naval reactor, naval reactors give the ship almost unlimited range and provide enough electrical energy to power a city of 100,000 people. The U.S. Navy previously operated Nuclear powered cruisers of the United States Navy, nuclear-powered cruisers, but all have been decommissioned. In the early 2010, the U.S. Navy had identified a need for 313 combat ships, but could only afford 232 to 243 ships. In March 2014, the Navy started counting self-deployable support ships such as minesweepers, surveillance craft, and tugs in the "battle fleet" to reach a count of 272 as of October 2016, and it includes ships that have been put in "shrink wrap". The number of ships generally ranged between 270 and 300 throughout the late 2010s. As of February 2022, the Navy has 296 battle force ships, however analyses state the Navy needs a fleet of more than 500 to meet its commitments.


Aircraft carriers

aircraft carrier An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and facilities for carrying, arming, deploying, and recovering aircraft. Typically, it is the capital ship of a fleet, as it allows a ...
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 combat system, 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. Modern carriers are United States ship naming conventions, named after American admirals and politicians, usually presidents. The Navy has a statutory requirement for a minimum of 11 aircraft carriers. Currently there are 10 that are deployable and one, , that is currently undergoing extensive systems and technologies testing until around 2021. All US aircraft carriers are Nuclear power, nuclear-powered; they and submarines are the only nuclear-powered Navy vessels.


Amphibious warfare vessels

Amphibious assault ships are the centerpieces of US amphibious warfare and fulfill the same power projection role as aircraft carriers except that their striking force centers on land forces instead of aircraft. They deliver, command, coordinate, and fully support all elements of a 2,200-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 LCACs. Amphibious transport docks are typically named after U.S. cities. The dock landing ship is a medium amphibious transport that is designed specifically to support and operate 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 cities or important places in U.S. and U.S. Naval history.


Cruisers

Cruisers 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 RIM-67 Standard, Standard missile with the Aegis combat system coordinating the two. s were the first to be equipped with 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 BGM-109 Tomahawk, Tomahawk missile gave cruisers additional long-range land and sea strike capability, making them capable of both offensive and defensive battle operations. The ''Ticonderoga'' class is the only active class of cruiser. All cruisers in this class are named after battles.


Destroyers

Destroyers are multi-mission medium surface ships capable of sustained performance in anti-air, anti-submarine, anti-ship, and offensive strike operations. Like cruisers, guided missile destroyers are primarily focused on surface strikes using BGM-109 Tomahawk, Tomahawk missiles and fleet defense through Aegis and the Standard missile. Destroyers additionally specialize in anti-submarine warfare and are equipped with ASROC, VLA rockets and Sikorsky SH-60 Seahawk, 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. With very few exceptions, destroyers are named after U.S. Navy, Marine Corps, and Coast Guard heroes.


Frigates and Littoral combat ships

Modern U.S. frigates mainly perform anti-submarine warfare for carrier and expeditionary strike 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. As in the case of destroyers, frigates are named after U.S. Navy, Marine Corps, and Coast Guard heroes. As of autumn 2015, the U.S. Navy has retired its most recent class of frigates and expects that by 2020 the Littoral Combat Ships (LCS) will assume many of the duties the frigate had with the fleet. The LCS is a class of relatively small surface vessels intended for operations in the littoral zone (close to shore). It was "envisioned to be a networked, agile, stealthy surface combatant capable of defeating anti-access and asymmetric threats in the littorals". They have the capabilities of a small assault transport, including a flight deck and hangar for housing two helicopters, a stern ramp for operating small boats, and the cargo volume and payload to deliver a small assault force with fighting vehicles to a roll-on/roll-off port facility. The ship is easy to reconfigure for different roles, including anti-submarine warfare, mine countermeasures, anti-surface warfare, intelligence, surveillance and reconnaissance, homeland defense, maritime intercept, special operations, and logistics, all by swapping mission-specific modules as needed. The LCS program is still relatively new as of 2018 with only ten active ships, but the navy has announced plans Littoral combat ship, for up to 32 ships. The navy has announced that a further 20 vessels to be built after that will be redesignated as 'frigates'. A special case is the , commissioned in 1797 as one of the original six frigates of the United States Navy, and which remains in commission at the Charlestown Navy Yard in Boston. She serves as a tribute to the heritage of the Navy, and occasionally sails for commemorative events such as Independence Day (United States), Independence Day and various victories during the
War of 1812 The War of 1812 (18 June 1812 – 17 February 1815) was fought by the United States of America and its indigenous allies against the United Kingdom and its allies in British North America, with limited participation by Spain in Florida. It be ...
. ''Constitution'' is currently the oldest commissioned warship afloat (, though older and also in common, is in permanent drydock).


Mine countermeasures ships

Mine countermeasures vessels are a combination of minehunters, a naval vessel that actively detects and destroys individual naval mines, and minesweepers, which clear mined areas as a whole, without prior detection of the mines. The navy has approximately a dozen of these in active service, but the mine countermeasure (MCM) role is also being assumed by the incoming classes of littoral combat ships. MCM vessels have mostly legacy names of previous US Navy ships, especially WWII-era minesweepers.


Patrol boats

A patrol boat is a relatively small naval vessel generally designed for coastal defense duties. There have been many designs for patrol boats, though the navy currently has only a single class. They may be operated by a nation's navy or coast guard, and may be intended for marine ("blue water") or estuarine or river ("brown water") environments. The Navy has approximately a dozen in active service, which are mainly used in the littoral regions of the

, but have also been used for home port patrols and drug interdiction missions. The navy's current class of patrol boats have names based on weather phenomena.


Submarines

All current and planned U.S. Navy submarines are nuclear-powered, as only nuclear propulsion allows for the combination of stealth and long duration, high-speed sustained underwater movement that makes modern nuclear submarines quite vital to a modern blue-water navy. The U.S. Navy operates three types: ballistic missile submarines, guided missile submarines, and attack submarines. U.S. Navy (nuclear) ballistic missile submarines carry the stealthiest leg of the U.S. strategic triad (the other legs are the land-based U.S. strategic missile force and the air-based U.S. strategic bomber force). These submarines have only one mission: to carry and, if called upon, to launch the Trident nuclear missile. The primary missions of attack and guided missile submarines in the U.S. Navy are peacetime engagement, surveillance and intelligence, special operations, precision strikes, and control of the seas. To these, attack submarines also add the battlegroup operations mission. Attack and guided missile submarines have several tactical missions, including sinking ships and other subs, launching cruise missiles, gathering intelligence, and assisting in special operations. As with other classes of naval vessels, most U.S. submarines (or "boats") are named according to specific conventions. The boats of the current U.S. ballistic missile submarine class, , are named after U.S. states. As the four current U.S. guided missile submarines are converted ''Ohio''-class boats, they have retained their U.S. state names. The members of the oldest currently-commissioned attack submarine class, the , are typically named for cities. The follow-on ' three submarines—''Seawolf'', ''Connecticut'' and ''Jimmy Carter''—share no consistent naming scheme. With the current attack submarines, the U.S. Navy has extended the ''Ohio'' class' state-based naming scheme to these submarines. 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 and foreigners with notable connections to the United States.


Aircraft

Carrier-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), including the U.S. Navy's premier Maritime Strike and only organic ASW aircraft, the venerable Sikorsky Sikorsky SH-60 Seahawk, MH-60R operated by Helicopter Maritime Strike Wing. The U.S. Navy began to research the use of aircraft at sea in the 1910s, with Lieutenant Theodore G. "Spuds" Ellyson becoming the first naval aviator on 28 January 1911, and commissioned its first aircraft carrier, , in 1922. 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 The Battle of the Coral Sea, from 4 to 8 May 1942, was a major naval battle between the Imperial Japanese Navy (IJN) and naval and air forces of the United States and Australia. Taking place in the Pacific Theatre of World War II, the batt ...

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-attack airplane is the multi-mission F/A-18E/F Super Hornet. The F-35 Lightning II, F-35C entered service in 2019. The Navy is also looking to eventually replace its F/A-18E/F Super Hornets with the F/A-XX program. 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.


Weapons

Current 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 RIM-67 Standard, 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 ESSM, RIM-162 Evolved Sea Sparrow Missile. In addition to missiles, the navy employs Mark 46 torpedo, Mark 46 and Mark 50 torpedoes and various types of naval mines. 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 AIM-9 Sidewinder, Sidewinder and the radar guided AIM-120 AMRAAM, AMRAAM missiles along with the M61 Vulcan cannon for close range dogfighting. For surface strikes, navy aircraft use a combination of missiles, smart bombs, and dumb bombs. On the list of available missiles are the AGM-65 Maverick, Maverick, Standoff Land Attack Missile, SLAM-ER and AGM-154 Joint Standoff Weapon, 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 use AGM-114 Hellfire, Hellfire and Penguin missile, Penguin air to surface missiles. Helicopters also employ various types of mounted anti-personnel machine guns, including the M60 machine gun, M60, M240 machine gun, M240, GAU-16/A, and Minigun, 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, submarine-launched ballistic missile (SLBM) with MIRV capability; the current Trident II (D5) version is expected to be in service past 2020. 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.
