The United States Navy uses hull classification symbols (sometimes called hull codes) to identify the types of its ships. The Royal Navy and some European and Commonwealth navies use a somewhat analogous system of Pennant numbers. USN redirects here. ... This article is about the navy of the United Kingdom. ... HMS Leeds Castle, launched in 1943 as a corvette with pennant number K384, was redesignated a frigate in 1948 and given the new flag superior F as seen here. ...

The combination of symbol and hull number identify a modern Navy ship uniquely. A heavily modified or repurposed ship may receive a new symbol, and either retain the hull number or receive a new one. Also, the system of symbols has changed a number of times since it was introduced in 1907, so ships' symbols sometimes change without anything being done to the physical ship.^[1] Year 1907 (MCMVII) was a common year starting on Tuesday (link will display the full calendar) of the Gregorian calendar (or a common year starting on Monday of the 13-day-slower Julian calendar). ...

Many of the symbols listed here are not presently in use. The Naval Vessel Register maintains an online database of US Navy ships. The Naval Vessel Register (NVR), official inventory of ships and service craft in custody or titled by the United States Navy, traces its origin back to the 1880s. ...

The 1975 ship reclassification of cruisers, frigates, and ocean escorts brought US Navy classifications into line with other nations' classifications, and eliminated the perceived "cruiser gap" with the Soviet Navy. The United States Navy reclassified many of its surface vessels in 1975, changing terminology and hull classification symbols for aircraft carriers, cruisers, frigates, and ocean escorts. ... The Soviet Navy (Russian: Военно-морской флот СССР, Voyenno-morskoy flot SSSR, literally Naval military forces of the USSR) was the naval arm of the Soviet armed forces. ...

If a ship's hull classification symbol begins with "W," it is a ship of the United States Coast Guard. If it begins with "T-", it is part of the Military Sealift Command and has a primarily civilian crew. USCG HH-65 Dolphin USCG HH-60J JayHawk The United States Coast Guard (USCG) is at all times a branch of the United States armed forces a maritime law enforcement agency, and a federal regulatory body. ... The Military Sealift Command (MSC) is a United States Navy (USN) organization that controls most of the replenishment and military transport ships of the Navy. ...

Warships

Warships are designed to participate in combat operations.

Aircraft Carrier type

All ships designed primarily for the purpose of conducting combat operations by aircraft which engage in attacks against airborne, surface, sub-surface and shore targets. The "CV" designation was originally derived from cruisers, since aircraft carriers were seen as an extension of the sea control and denial mission of cruisers. The "V" designation for heavier than air craft comes from the French verb "Voler" (to fly).^[2] Contrary to popular belief, the "CV" hull classification symbol does not stand for "Carrier Vessel". Since 1935, "CV" has been a two-letter, unitary hull classification symbol, meaning "aircraft carrier." Aircraft carriers are designated in two sequences: The first, which has run from CV-1 USS Langley to the very latest ships, and the second, the CVE escort carrier sequence, ran from CVE-1 Long Island to CVE-128 Okinawa before being discontinued.

Surface Combatant type

Surface ships which are designed primarily to engage enemy forces on the high seas. The primary surface combatants are battleships, cruisers and destroyers. Battleships are very heavily armed and armored; cruisers moderately so; destroyers and smaller warships, less so. Before 1920, ships were called "<type> no. X," with the type fully pronounced. The types were commonly abbreviated in ship lists to "B-X," "C-X," "D-X" et cetera - for example, before 1920, USS Minnesota (BB-22) would have been called "USS Minnesota, Battleship number 22" verbally and "USS Minnesota, B-22" in writing. After 1920, the ship's name would have been both written and pronounced "USS Minnesota (BB-22)" In generally decreasing size, the types are: USS Minnesota (BB-22), a Connecticut-class battleship, was the second ship of the United States Navy in honor of the 32nd state. ...
