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.

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 chief of naval operations (CNO) is the highest-ranking officer of the United States Navy. The position is a statutory office () held by an Admiral (United States), admiral who is a military adviser and deputy to the United States Secretary ...

on 17 October 2007.
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. The British

A provision of the 2018
National Defense Authorization Act called for expanding the naval fleet to 355 ships "as soon as practicable", but did not establish additional funding nor a timeline.
Organization

The U.S. 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 a member of the
Joint Chiefs of Staff
The Joint Chiefs of Staff (JCS) is the body of the most senior uniformed leaders within the United States Department of Defense, which advises the president of the United States, the secretary of defense, the Homeland Security Council and ...
(JCS), though the JCS plays only 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 commanders of the
unified combatant commands.
Operating forces
There are eight components in the operating forces of the U.S. Navy:

. These seven 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 admirals. The
United States First Fleet existed after World War II from 1947, but it was redesignated the Third Fleet in early 1973. The Second Fleet was deactivated in September 2011 but reestablished in August 2018 amid heightened tensions with Russia. It is headquartered in Norfolk, Virginia, with responsibility over the East Coast and North Atlantic. In early 2008, the Navy reactivated the Fourth Fleet to control operations in the area controlled by Southern Command, which consists of US assets in and around Central and South America. Other number fleets were activated during World War II and later deactivated, renumbered, or merged.
Shore establishments

Relationships with other service branches
United States Marine Corps

United States Marine Corps
The United States Marine Corps (USMC), also referred to as the United States Marines or simply the Marines, is the maritime land force service branch of the United States Department of Defense. It is responsible for conducting expeditionar ...
came under the Department of the Navy. Historically, the Navy has had a unique relationship with the 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 Marine Corps is a distinct, separate service branch
with its own uniformed service chief – the Commandant of the Marine Corps, a four-star general.
The Marine Corps depends on the Navy for medical support (dentists,
doctors, nurses, medical technicians known as
corpsmen) and religious support (chaplains). Thus, Navy officers and enlisted sailors 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 uniform
Full dress uniform, also known as a ceremonial dress uniform or parade dress uniform, is among the most formal wear, formal type of uniform used by military, police, firefighter, fire and other public uniformed services for official parade (mili ...
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.
United States Coast Guard

Law Enforcement Detachments (LEDETs) to Navy vessels, where they perform arrests and other law enforcement duties during naval boarding and interdiction missions. In times of war, the Coast Guard may be called upon to operate as a service within the Navy. 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.
Personnel

The United States Navy has over 400,000 personnel, approximately a quarter of whom are in ready reserve. Of those on active duty, more than eighty percent are
enlisted sailors and around fifteen percent are
commissioned officer
An officer is a person who holds a position of authority as a member of an armed force or uniformed service.
Broadly speaking, "officer" means a commissioned officer, a non-commissioned officer (NCO), or a warrant officer. However, absent ...
s; the rest are
midshipmen of the United States Naval Academy and midshipmen of the
Naval Reserve Officer Training Corps at over 180 universities around the country and officer candidates at the Navy's
Officer Candidate School.
Enlisted sailors complete basic military training at
boot camp and then are sent to complete training for their individual
careers.
Sailors prove they have mastered skills and deserve responsibilities by completing Personnel Qualification Standards (PQS) tasks and examinations. Among the most important is the "warfare qualification", which denotes a journeyman level of capability in Surface Warfare, Aviation Warfare, Information Dominance Warfare, Naval Aircrew, Special Warfare, Seabee Warfare, Submarine Warfare or Expeditionary Warfare. Many qualifications are denoted on a sailor's uniform with
U.S. Navy badges and insignia.
Uniforms
The uniforms of the U.S. Navy have evolved gradually since the first uniform regulations for
officers were issued in 1802 on the formation of the Navy Department. The predominant colors of U.S. Navy uniforms are navy blue and white. U.S. Navy uniforms were based on Royal Navy uniforms of the time and have tended to follow that template.
Commissioned officers
Navy officers serve either as a
line officer
A line officer or officer of the line is, opposed to staff officers or reserve officers, a military officer who is eligible for command of operational, tactical or combat units. The name most likely stems from the Early modern warfare tactics ...
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
chief petty officer pay grades, E-7 through E-9, analogous to a senior non-commissioned officer in the other services, and must have a minimum 14 years in service.
Enlisted
Sailors in pay grades E-1 through E-3 are considered to be in apprenticeships.
They are divided into five definable groups, with colored group rate marks designating the group to which they belong: Seaman, Fireman, Airman, Constructionman, and Hospitalman. E-4 to E-6 are

s in the Navy.
Petty Officers perform not only the duties of their specific career field but also serve as leaders to junior enlisted personnel. E-7 to E-9 are still considered Petty Officers, but are considered a separate community within the Navy. They have separate berthing and dining facilities (where feasible), wear separate uniforms, and perform separate duties.
After attaining the rate of Master Chief Petty Officer, a service member may choose to further their career by becoming a
Command Master Chief Petty Officer (CMC). A CMC is considered to be the senior-most enlisted service member within a command, and is the special assistant to the
Commanding Officer
The commanding officer (CO) or commander, or sometimes, if the incumbent is a general officer, commanding general (CG), is the officer in command of a military unit. The commanding officer has ultimate authority over the unit, and is usually give ...
in all matters pertaining to the health, welfare, job satisfaction, morale, use, advancement and training of the command's enlisted personnel.
CMCs can be Command level (within a single unit, such as a ship or shore station), Fleet level (squadrons consisting of multiple operational units, headed by a flag officer or commodore), or Force level (consisting of a separate community within the Navy, such as Subsurface, Air, Reserves).
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, and gold stars for Force. Additionally, CMCs wear a badge, worn on their left breast pocket, denoting their title (Command/Fleet/Force).
Badges of the United States Navy
Insignia and badges of the United States Navy are military "badges" issued by the Department of the Navy to naval service members who achieve certain qualifications and accomplishments while serving on both active and reserve duty in the United States Navy. Most naval aviation insignia are also permitted for wear on uniforms of the

In 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.

. 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. Modern carriers are
named after American admirals and politicians, usually presidents.
The Navy has a statutory requirement for a minimum of 11 aircraft carriers. All 11 carriers are currently active, ten and one .
Aircraft Carrier Capacity
Aircraft Carriers have the ability to house 5,000 people. This is the size of a small town floating in the ocean. Aircraft carriers also have up to 90 aircraft on the ship at one time.

(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

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.
The Navy operates 32 amphibious warfare ships, eight and two amphibious assault ships, four and six dock landing ships, and 12 amphibious transport dock ships.
Cruisers
Cruiser
A cruiser is a type of warship. Modern cruisers are generally the largest ships in a fleet after aircraft carriers and amphibious assault ships, and can usually perform several operational roles from search-and-destroy to ocean escort to sea ...
s 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 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
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
Destroyer
In naval terminology, a destroyer is a fast, maneuverable, long-endurance warship intended to escort
larger vessels in a fleet, convoy, or carrier battle group and defend them against a wide range of general threats. They were conceived i ...
s 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 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. With very few exceptions, destroyers are named after U.S. Navy, Marine Corps, and Coast Guard heroes.
The U.S. Navy currently has 75 destroyers, 73 destroyers and two stealth destroyers, with a third (the ) expected to enter service sometime in 2024.
Frigates and Littoral combat ships
Modern U.S.
frigate
A frigate () is a type of warship. In different eras, the roles and capabilities of ships classified as frigates have varied.
The name frigate in the 17th to early 18th centuries was given to any full-rigged ship built for speed and maneuvera ...
s 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.
In late 2015, the U.S. Navy retired its most recent class of traditional frigates in favor of the littoral combat ship (LCS), relatively small vessels designed for near-shore operations that was expected to assume many of the duties the frigate had with the fleet. The LCS was "envisioned to be a networked, agile, stealthy surface combatant capable of defeating
anti-access and
asymmetric threats in the
littorals", although their ability to perform these missions in practice has been called into question. The Navy has announced it plans to reduce procurement of the LCS and retire early examples of the type.
In the future, the Navy plans to purchase up to 20 of the , based on the

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

"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, 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.

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
The Harpoon is an all-weather, over-the-horizon, anti-ship missile
manufactured by McDonnell Douglas (now Boeing Defense, Space & Security). The AGM-84E Standoff Land Attack Missile (SLAM) and later AGM-84H/K SLAM-ER (Standoff Land Attack M ...
. 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

Naval post offices
During World War I the first U.S. government post offices were established aboard Navy ships, managed by a Navy postal clerk. Prior to this, mail from crew members was collected and at the first opportunity was dropped off at a port of call where it was processed at a US Post Office. Before the arrival of email and the internet, hand stamped mail was the only way Navy crew members at sea could communicate with their family, friends and others. Mail was considered almost as valuable to crew members as food and ammunition. Sometimes mail from various crew members (referred to by historians and collectors as postal history), is directly associated with naval history. Letters and other correspondence sent by commanders, officers and crew members can include names, ranks, signatures, addresses, and ship's postmarks which can often confirm dates and locations of naval ships and crew members during various battles or other naval operations. As such, naval mail can serve as a source of information to naval historians and biographers. Among the more notable examples of Naval postal history include letters sent from the USS Arizona, USS ''Arizona'', before and on 7 December 1941.
