USS Bellatrix (AK-20/AKA-3) was an Arcturus-class attack cargo ship in the United States Navy during World War II and the Korean War. Originally ordered as a C2-T cargo ship named Raven for the Maritime Commission, the vessel was transferred to United States Navy control while under construction and launched in August 1941.
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.
Type C2 ships were designed by the United States Maritime Commission (MARCOM) in 1937–38. They were all-purpose cargo ships with five holds, and U.S. shipyards built 328 of them from 1939 to 1945. Compared to ships built before 1939, the C2s were remarkable for their speed and fuel economy. Their design speed was 15.5 knots (28.7 km/h), but some could make 19 knots (35 km/h) on occasion. The first C2s were 459 feet (140 m) long, 63 feet (19 m) broad, and 40 feet (12 m) deep, with a 25-foot (8 m) draft. Later ships varied somewhat in size. Some, intended for specific trade routes, were built with significant modifications in length and capacity.
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.
USS Algorab (AKA-8) was laid down as Mormacwren, one of the earliest Maritime Commission-type C2 ships, on 10 August 1938 by the Sun Shipbuilding & Drydock Co., Chester, Pennsylvania as hull 177 for Moore-McCormack. Mormacwren was acquired by the United States Navy 6 June 1941, commissioned 15 June 1941 as USS Algorab (AK-25) and was redesignated an attack transport on 1 February 1943 with the hull number chanted to AKA-8. Algorab decommissioned on 3 December 1945 and was delivered to the Maritime Commission on 30 June 1946 for disposal, purchased by Wallem & Co. on 4 April 1947 for commercial service.
The Tolland-class attack cargo ships were built by North Carolina Shipbuilding Co. in Wilmington, North Carolina during the latter stages of World War II.
The Andromeda-class attack cargo ships were a class of amphibious cargo ship built by Federal Shipbuilding & Drydock Co. in Kearny, New Jersey, and Moore Dry Dock Co., in Oakland, California, during World War II. Like all attack cargo ships, they were designed to carry combat loaded military cargo and landing craft, and to use the latter to land weapons, supplies, and troops on enemy shores during amphibious operations.
The Artemis-class attack cargo ships were a series of attack cargo ships (AKAs) built by Walsh-Kaiser Company of Cranston and Providence, Rhode Island, during World War II.
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.
Type C3-class ships were the third type of cargo ship designed by the United States Maritime Commission (MARCOM) in the late 1930s. As it had done with the Type C1 ships and Type C2 ships, MARCOM circulated preliminary plans for comment. The design presented was not specific to any service or trade route, but was a general purpose ship that could be modified for specific uses. A total of 162 C3 ships were built from 1939 to 1946.
The Bayfield-class attack transport was a class of US Navy attack transports that were built during World War II.
The Sumter-class attack transport was a class of attack transport built for service with the US Navy in World War II.
The Ormsby-class attack transport was a class of US Navy attack transport that saw service in World War II.
The Crescent City-class attack transport was a class of U.S. Navy attack transports that saw service in World War II and the Korean War. There were four ships in the class: USS Crescent City, USS Charles Carroll, USS Monrovia, and USS Calvert.
The Harris-class attack transport was a class of US Navy attack transport which saw service in World War II. The purpose of any attack transport was to deliver troops and their equipment to hostile shores in order to execute amphibious invasions using an array of smaller integral landing craft. Being intended to serve in forward combat areas, these ships were well armed with antiaircraft guns to protect itself and its vulnerable cargo of troops from air attack in the battle zone.
The President Jackson-class attack transport was a class of seven US Navy attack transport that saw service in World War II.
USS Arcturus (AK-18/AKA-1) was an Arcturus-class attack cargo ship named after Arcturus, a star in the constellation Boötes. She served as a commissioned ship for 5 years and 5 months.
The T3 tanker, or T3, are a class of seaworthy large tanker ships produced in the United States and used to transport fuel oil, gasoline or diesel before and during World War II, the Korean War and the Vietnam War. The T3 tanker classification is still used today. The T3 tanker has a full load displacement of about 24,830 tons.
SS Logan Victory was a cargo Victory ship built for World War II under the Emergency Shipbuilding program. The Logan Victory was launched January 16, 1945, by Permanente Metals Corporation, Richmond, California and completed on February 6, 1945. She was operated by the American-Hawaiian Steamship Company under the United States Maritime Commission.
SS Hobbs Victory was a cargo Victory ship built for World War II under the Emergency Shipbuilding program. Hobbs Victory, was launched on January 9, 1945 by Permanente Metals Corporation, Richmond, California and completed on January 9, 1945. She was built in just 87 days. She was operated by the Sudden & Christenson for the United States Maritime Commission.
