USS PC-815 was a PC-461-class submarine chaser built for the United States Navy during World War II. Its first commander, for about eighty days in 1943, was L. Ron Hubbard, who later became the founder of Scientology. After Hubbard was removed from command for conducting unauthorized gunnery practice in Mexican territorial waters, the PC-815 served as a shore patrol vessel off San Diego, California.
The Admirable class was one of the largest and most successful classes of minesweepers ordered by the United States Navy during World War II. Typically, minesweepers detected and removed naval mines before the rest of the fleet arrived, thereby ensuring safe passage for the larger ships. They were also charged with anti-submarine warfare (ASW) duties with rear-mounted depth charge racks and a forward-firing Hedgehog antisubmarine mortar. Their job was essential to the safety and success of U.S. naval operations during World War II and the Korean War. These minesweepers were also employed as patrol vessel and convoy escorts.
USS PC-1264 was a PC-461-class submarine chaser built for the United States Navy during World War II. She was one of only two U.S. Navy ships to have a predominantly African-American enlisted complement during the war, the other being the Evarts-class destroyer escortUSS Mason.
A submarine chaser or subchaser is a small naval vessel that is specifically intended for anti-submarine warfare. Many of the American submarine chasers used in World War I found their way to Allied nations by way of Lend-Lease in World War II.
The Defoe Shipbuilding Company was a small ship builder established in 1905 in Bay City, Michigan, United States. It ceased to operate in 1976 after failing to renew its contracts with the United States Navy. The site of the former company is now being developed for business and housing on the bank of the Saginaw River.
The Type 062 gunboat is a class of gunboat of the People's Liberation Army Navy first developed and constructed in the 1950s. This unsophisticated class is relatively well-armed for its size and is the most widely built and exported Chinese naval vessel in terms of numbers. A total of 30 were built, initial boats being known as the Shanghai I class and later slightly improved boats being known as the Shanghai II class. The Shanghai I class was slightly smaller than its successor, the Shanghai II class, displacing 125 tons instead of 135 tons, and had a twin Chinese Type 66 57 mm gun mount forward. All other specifications are identical to the Shanghai II class, which replaced the 57 mm with twin 37 mm gun mounts. Some boats remained in active service well into the early 1990s in the PLA navy and longer in the case of the Korean People's Navy.
USS Adroit (AM-82/PC-1586) was an Adroit-class minesweeper acquired by the United States Navy for the task of removing mines that had been placed in the water to prevent the safe passage of ships.
The Adroit-class minesweepers were a class of United States Navy PC-461-class submarine chasers completed as minesweepers. However, they were considered unsatisfactory in this role, and were all eventually converted back into submarine chasers.
USS Daring (AM-87) was an Adroit-class minesweeper of the United States Navy.
USS Direct (AM-90) was an Adroit-class minesweeper of the United States Navy. It was laid down on 26 December 1941 by the Dravo Corporation, Neville Island, Pittsburgh, Pennsylvania, launched on 25 April 1942, and commissioned on 31 August 1942. The ship started conversion to a submarine chaser on 16 May 1944 at Norfolk, Virginia, and was reclassified PC-1594 on 1 June 1944.
Dravo Corporation was a shipbuilding company with shipyards in Pittsburgh and Wilmington, Delaware. It was founded by Frank and Ralph Dravo in Pittsburgh in 1891. The corporation went public in 1936 and in 1998 it was bought out by Carmeuse for $192 million. On March 5, 1942, it became the first corporation to receive the Army-Navy "E" Award for outstanding war time production. Dravo ranked 72nd among United States corporations in the value of World War II military production contracts.
The PCE-842-class patrol craft were United States Navy patrol craft escorts designed during World War II that were intended for coastal and convoy escort. The design was derived from the 180-foot (55 m) Admirable-class minesweeper as a substitute for the 173-foot (53 m) PC-461-class submarine chasers that were used for anti-submarine warfare (ASW) in coastal areas. At 185 feet long and 640 tons, the PCE is more than twice the displacement of the PC and thus and in combination with a less powerful engine also much slower. It has a crew complement of 99 officers and men.
The Cleveland Diesel Engine Division of General Motors (GM) was a leading research, design and production facility of diesel engines from the 1930s to the 1960s that was based in Cleveland, Ohio. The Cleveland Diesel Engine Division designed several 2 stroke diesel engines for submarines, tugboats, destroyer escorts, Patapsco-class gasoline tankers and other marine applications. Emergency generator sets were also built around the Cleveland Diesel and were installed in many US warships. The division was created in 1938 from the GM-owned Winton Engine Corporation and was folded into the GM Electro-Motive Division in 1962. The engines continue in use today on older tugs.

US Navy Small Craft Training Centers(SCTC) were United States Navy training bases used to train sailors in the operation of the many small wooden crafts used in World War II. These crafts were given the nickname Splinter Fleet. There was a shortage of steel and steel shipyards during World War II, so there was a need for a vast wooden fleet of crafts. The Small Craft Training Centers had classrooms and crafts for training. The bases had barrack housing and mess halls. To get the men and crafts out into the field quickly, at many of the bases men trained on new ships. The new ships were at the center for about 4 weeks as part of the vessel's sea trial. Tugboats, Minesweepers, Net laying ships, Crash boats, PT boats and other crafts built near the center were taken to the Small Craft Training Centers for testing. Crafts built at Lynch Shipbuilding in San Diego, California were taken to the Small Craft Training Center at Terminal Island, San Pedro, California for their sea trial. Lynch Shipbuilding built tugboats, and minesweepers. Some of the craft at the Terminal Island school were: USS Density (AM-218), USS Waxsaw (AN-91), and USS Climax (AM-161), USS Wateree (ATF-117), USS Quest (AM-281), USS Snowbell (AN-52). The US Navy also had Small Craft Training Centers in Miami, Florida, Santa Barbara, California, New Orleans, Louisiana and other sites.
