The escort carrier or escort aircraft carrier, also called a "jeep carrier" or "baby flattop" in the United States Navy (USN) or "Woolworth Carrier" by the Royal Navy, was a small and slower type of aircraft carrier used by the Royal Navy, the Royal Canadian Navy, the United States Navy, the Imperial Japanese Navy and Imperial Japanese Army Air Force in World War II. They were typically half the length and a third the displacement of larger fleet carriers, more-lightly armed and armored, and carried fewer planes. Escort carriers were most often built upon a commercial ship hull, so they were cheaper and could be built quickly. This was their principal advantage as they could be completed in greater numbers as a stop-gap when fleet carriers were scarce. However, the lack of protection made escort carriers particularly vulnerable, and several were sunk with great loss of life. The light carrier was a similar concept to the escort carrier in most respects, but was fast enough to operate alongside fleet carriers.
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.
High-speed transports were converted destroyers and destroyer escorts used in US Navy amphibious operations in World War II and afterward. They received the US Hull classification symbol APD; "AP" for transport and "D" for destroyer. In 1969, the remaining ships were reclassified as "Fast Amphibious Transports", hull symbol LPR.
Landing craft are small and medium seagoing watercraft, such as boats and barges, used to convey a landing force from the sea to the shore during an amphibious assault. The term excludes landing ships, which are larger. Production of landing craft peaked during World War II, with a significant number of different designs produced in large quantities by the United Kingdom and United States.
The Iwo Jima-class amphibious assault ships of the United States Navy were the first amphibious assault ships designed and built as dedicated helicopter carriers, capable of operating up to 20 helicopters to carry up to 1,800 marines ashore. They were named for battles featuring the United States Marine Corps, starting with the Battle of Iwo Jima. The first ship of the class was commissioned in 1961, and the last was decommissioned in 2002. The hull classification of "LPH" stands for "Landing Platform Helicopter".
A Landing Craft Utility (LCU) is a type of boat used by amphibious forces to transport equipment and troops to the shore. They are capable of transporting tracked or wheeled vehicles and troops from amphibious assault ships to beachheads or piers.
The Republic of Vietnam Navy (RVNN; Vietnamese: Hải quân Việt Nam Cộng hòa - HQVNCH; was the naval branch of the South Vietnamese military, the official armed forces of the former Republic of Vietnam from 1955 to 1975. The early fleet consisted of boats from France; after 1955, and the transfer of the armed forces to Vietnamese control, the fleet was supplied from the United States. With American assistance, in 1972 the VNN became the largest Southeast Asian navy and, by some estimates, the fourth largest navy in the world, just behind the Soviet Union, the United States and the People's Republic of China, with 42,000 personnel, 672 amphibious ships and craft, 20 mine warfare vessels, 450 patrol craft, 56 service craft, and 242 junks. Other sources state that VNN was the ninth largest navy in the world. The Republic of Vietnam Navy was responsible for the protection of the country's national waters, islands, and interests of its maritime economy, as well as for the co-ordination of maritime police, customs service and the maritime border defence force.
Amphibious cargo ships were U.S. Navy ships designed specifically to carry troops, heavy equipment and supplies in support of amphibious assaults, and to provide naval gunfire support during those assaults. A total of 108 of these ships were built between 1943 and 1945—which worked out to an average of one ship every eight days. Six additional AKAs, featuring new and improved designs, were built in later years. They were originally called Attack Cargo Ships and designated AKA. In 1969, they were renamed as Amphibious Cargo Ships and redesignated LKA.
Kashii was the third and final vessel completed of the three light cruisers in the Katori class, which served with the Imperial Japanese Navy (IJN) during World War II. The ship was named after a noted Shinto shrine in Fukuoka, Japan.
Attack transport is a United States Navy ship classification for a variant of ocean-going troopship adapted to transporting invasion forces ashore. Unlike standard troopships – often drafted from the merchant fleet – that rely on either a quay or tenders, attack transports carry their own fleet of landing craft, such as the landing craft, vehicle, personnel (LCVP) or Higgins boat.
Haskell-class attack transports (APA) were amphibious assault ships of the United States Navy created in 1944. They were designed to transport 1,500 troops and their combat equipment, and land them on hostile shores with the ships' integral landing craft.
The 3-inch/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.
A net laying ship, also known as a net layer, net tender, gate ship or boom defence vessel was a type of naval auxiliary ship.
An amphibious warfare ship is an amphibious vehicle warship employed to land and support ground forces, such as marines, on enemy territory during an amphibious assault.
Akitsu Maru (あきつ丸) was a Japanese "Type C" landing craft depot ship and escort aircraft carrier operated by the Imperial Japanese Army (IJA). In some sources Akitsu Maru and Nigitsu Maru are also considered to be the first amphibious assault ships, although, this title can be disputed with Shinshū Maru that served a similar role, and being a template for Akitsu Maru.
The Ashland-class dock landing ship were the first class of dock landing ship of the United States Navy. They were built during World War II. A dock landing ship is a form of auxiliary warship designed to support amphibious operations. Eight ships were built for the United States Navy and they remained in US service until the 1960s. Two of the class were sold for export overseas, with one joining the Republic of China Navy and the other the Argentinian Navy. The two transferred ships stayed in service until the 1980s. All eight ships were scrapped.
The Adirondack-class command ship was a ship class of command ships of the United States Navy during World War II and the Cold War. All 3 ships were converted from the Type C2-S-AJ1 cargo ships.
The Appalachian-class command ship was a ship class of command ships of the United States Navy during World War II. All 4 ships were converted from the Type C2-S-B1 cargo ships.
The Paul Revere-class attack transport was a ship class of attack transports of the United States Navy during the Cold War. Both ships were converted from the Type C4-S-1A cargo ships, and would be the last attack transports to be procured by the Navy.
The Osumi-class tank landing ship were a class of transport ships operated by the Maritime Self-Defense Force. It was recommissioned with the donation of three LST-542-class tank landing ship from the US Navy. Initially, it was categorized as a amphibious landing ship, but the ship type was changed on 1 April 1971.
