The United States Navy, United States Coast Guard, and United States National Oceanic and Atmospheric Administration (NOAA) use a hull classification symbol to identify their ships by type and by individual ship within a type. The system is analogous to the pennant number system that the Royal Navy and other European and Commonwealth navies use.
A naval ship is a military ship used by a navy. Naval ships are differentiated from civilian ships by construction and purpose. Generally, naval ships are damage resilient and armed with weapon systems, though armament on troop transports is light or non-existent.
A warship or combatant ship is a ship that is built and primarily intended for naval warfare. Usually they belong to the armed forces of a nation. As well as being armed, warships are designed to withstand damage and are typically faster and more maneuverable than merchant ships. Unlike a merchant ship, which carries cargo, a warship typically carries only weapons, ammunition and supplies for its crew. Warships usually belong to a navy, though they have also been operated by individuals, cooperatives and corporations.
The names of commissioned ships of the United States Navy all start with USS, for United States Ship. Non-commissioned, primarily civilian-crewed vessels of the U.S. Navy under the Military Sealift Command have names that begin with USNS, standing for United States Naval Ship. A letter-based hull classification symbol is used to designate a vessel's type. The names of ships are selected by the Secretary of the Navy. The names are those of states, cities, towns, important persons, important locations, famous battles, fish, and ideals. Usually, different types of ships have names originated from different types of sources.
The People's Liberation Army Navy Surface Force is the surface warfare branch of China's People's Liberation Army Navy (PLAN), consisting of all surface vessels in operational service with the PLAN. The PLAN Surface Force operates 661 ships organized into three fleets: the North Sea Fleet, the East Sea Fleet and the South Sea Fleet.
The 3"/50 caliber gun in United States naval gun terminology indicates the gun fired a projectile 3 inches (76 mm) in diameter, and the barrel was 50 calibers long. Different guns of this caliber were used by the U.S. Navy and U.S. Coast Guard from 1900 through to 1990 on a variety of combatant and transport ship classes.
USS Zeus (ARB-4) was planned as a United States Navy LST-1-class tank landing ship, but was redesignated as one of twelve Aristaeus-class battle damage repair ships built for the United States Navy during World War II. Named for Zeus, she was the only US Naval vessel to bear the name.
The Royal Canadian Navy uses hull classification symbols to identify the types of its ships, which are similar to the United States Navy's hull classification symbol system. The Royal Navy and some European and Commonwealth navies use a somewhat analogous system of pennant numbers.
For the April 1945 invasion of Okinawa, the Allies assembled the most powerful naval force in history. Since the few remaining capital ships of the Imperial Japanese Combined Fleet had been sunk or otherwise put out of action at the Battle of Leyte Gulf, the Allies were effectively unopposed in terms of major surface vessels; a single mission consisting of the superbattleship Yamato and a few escorts was undertaken, but the task force did not get within 200 nautical miles of the invasion area. The main Japanese naval opposition within the invasion area came from hundreds of Imperial Japanese Navy Shin'yō-class suicide motorboats and Maru-Ni Imperial Japanese Army attack boats.
On 15 June 1944, United States Marine and Army forces landed on the southwest coast of the island of Saipan in the central Marianas chain. US forces declared Saipan secure on 9 July.
Naval Base Ulithi was a major United States Navy base at the Ulithi Atoll in the Caroline Islands in the western Pacific Ocean, to the north of New Guinea during World War II. The base was built to support the island-hopping Pacific war efforts of the Allied nations fighting the Empire of Japan. In terms of the number of ships at one base, Naval Base Ulithi was the largest naval base in the world in 1944 and 1945, with over 600 ships at times.
This glossary defines the various types of ships and accessory watercraft that have been used in service of the United States. Such service is mainly defined as military vessels used in the United States Navy and United States Coast Guard, as well as the defunct, incorporated, or renamed institutions such as the United States Revenue Cutter Service. Service of the United States can also be defined in this context as special government missions in the form of expeditions, such as the Wilkes Expedition or the North Pacific Exploring and Surveying Expedition. The scope of the glossary encompasses both the "Old Navy" of the United States, from its beginnings as the "Continental Navy", through the "New Navy" and up to modern day. The watercraft included in the glossary are derived from United States ships with logbooks published by the National Archives and Records Administration.
Naval Base Eniwetok was a major United States Navy base located at Enewetak Atoll in the Marshall Islands, during World War II. The base was built to support the island-hopping strategy used by allied nations fighting the Empire of Japan in the Pacific War. During 1944-5 Eniwetok was one of the busiest naval bases in the world with over 488 ships.
