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.
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 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.
A motor torpedo boat is a fast torpedo boat, especially of the mid 20th century. The motor in the designation originally referred to their use of petrol engines, typically marinised aircraft engines or their derivatives, which distinguished them from other naval craft of the era, including other torpedo boats, that used steam turbines or reciprocating steam engines. Later, diesel-powered torpedo boats appeared, in turn or retroactively referred to as "motor torpedo boats" for their internal combustion engines, as distinct from steam powered reciprocating or turbine propulsion.
The motor gunboat (MGB) was a small, high-speed British military vessel of the Second World War, which was armed with a mix of guns, in contrast to the physically similar motor torpedo boat (MTB), whose main offensive weapon were torpedoes. The small size of the MGBs, and their high speed, made them difficult targets for German E-boats, though, like their opponents, they were limited by heavy weather, because they did not provide a stable-enough platform to aim the guns. The large number of guns meant the crew was relatively large, numbering as high as thirty men on the largest boats.
The Landing Craft Infantry (LCI) were several classes of landing craft used by the Allies to land large numbers of infantry directly onto beaches during World War II. They were developed in response to a British request for seagoing amphibious assault ships capable of carrying and landing substantially more troops than their smaller assault landing craft (LCA). The result was a small steel ship that could land 200 men, traveling from rear bases on its own bottom at a speed of up to 15 knots.
The Fairmile B motor launch was a very numerous class of motor launch produced in kit form by British boatbuilder Fairmile Marine, and then assembled and fitted out by numerous boatyards during the Second World War to meet the Royal Navy's coastal operation requirements.
Coastal Forces was a division of the Royal Navy initially established during World War I, and then again in World War II under the command of Rear-Admiral, Coastal Forces. It remained active until the last minesweepers to wear the "HM Coastal Forces" cap tally were taken out of reserve in 1968. The division received more gallantry awards than any other branch of the Royal Navy during that period.
The Coastal Forces of the Royal Canadian Navy (RCN) was a specialized naval force of well-armed, small and fast motor launch (ML) and motor torpedo boat (MTB) flotillas, primarily crewed by members of the Royal Canadian Naval Volunteer Reserve (RCNVR). Tasked with escort, coastal defence, anti-submarine, minesweeping and search and rescue duties, the Coastal Forces of the RCN contributed to securing Allied sea lines of communication off the coasts of Canada and Britain during the Second World War.
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.
USS LSM(R)-190 was a United States Navy LSM(R)-188-class Landing Ship Medium (Rocket). She was built at Charleston Navy Yard, Charleston, South Carolina and was commissioned on 21 November 1944. LSM(R)-190 took part in the Battle of Okinawa from 7 April–4 May 1945. She was hit and sunk by a Japanese suicide plane on 4 May 1945 while on the radar picket line. She later received a Navy Unit Commendation for her service off Okinawa.
LSM(R)-193 was an American Landing Ship Medium (Rocket) built in 1944, which provided naval gunfire and rocket support for US and Allied amphibious landings in World War II. It was laid down at Charleston Navy Yard and commissioned on 21 November 1944. It participated in the Battle of Okinawa as well as the run-up to the battle
USS LCS(L)(3)-102 is an LCS(L)(3)-1 Class Landing Craft Support ship built for the United States Navy during World War II. The vessel was completed near the end of the war and saw brief service during the Battle of Okinawa. After the war, LCS(L)(3)-102 served in China before being decommissioned in 1946 and then transferred to Japan in mid-1953. Serving under the name JDS Himawari, the vessel remained in Japan until mid-1966 when she was transferred to Thailand, becoming the HTMS Nakha. In 2007, after being retired, the ship was returned to the United States to become a museum ship.
Albina Engine & Machine Works was a shipyard along the Willamette River in Portland, Oregon, United States. It was located in the Albina area of Portland along N. River Street and N. Loring Street. Albina Engine & Machine Works was founded in 1904. The shipyard produced a number of freighters during World War I, but operated mainly as a repair yard during the 1920s and 1930s. The Albina yard expanded its workforce and production during Portland's World War II shipbuilding boom. It specialized in producing subchasers, vessels designed to combat German U-boats. Albina Engine & Machine Works also built Landing Craft Support boats and cargo ships. Business declined in the post-war years, and Albina Engine & Machine Works was sold to the Dillingham Corporation around 1971.
The Canadian Fairmile B was a motor launch built during the Second World War for the Royal Canadian Navy. They were adaptations of the British Fairmile B motor launch design incorporating slight modifications for Canadian climatic and operational conditions. Eighty-eight were built in Canada for service with the Coastal Forces of the Royal Canadian Navy in home waters, of which eight were supplied to the United States Navy.
Landing Craft, Gun (LCG) is an umbrella term referring to two major types of British-built landing craft used extensively in World War II, present for the Normandy landings, the Allied invasion of Sicily, Operation Infatuate, and more. Their primary purpose was to provide direct fire against beach positions and surface attack for first-echelon landing waves. Secondary roles included engaging light surface vessels and escorting other landing craft.
Splinter fleet or Splinter navy was a nickname given to the United States wooden boats used in World War II. The boats served in many different roles during the war. These boats were built in small boatyards on the West coast and East coast, Great Lakes and the Gulf of Mexico. They could be built quickly, in just 60 to 120 days. Most of the boats were built by boatyards that already had the tools and knowledge from building yachts, sailboats and motor boats. Many were built by craftsmen in family-owned small businesses. Under the Emergency Shipbuilding Program and War Shipping Administration contracts went out to over fifty boatyards across the country. The boats were built for the US Navy, the United States Army Air Forces, United States Coast Guard, and US Army. Some of the wooden boats went to Allied nations on the Lend-Lease program.
