A motor minesweeper is a small minesweeper, powered by an internal combustion engine, very often of wooden construction, designed to locate and destroy mines in coastal waters and harbors. Many navies have used such ships.
Motor minesweepers include:
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.
USS Admirable (AM-136) was the lead ship of her class of minesweeper built for the United States Navy during World War II. In commission from 1943 to 1945, she was transferred to the Soviet Navy in 1945 and served as T-331 until stricken in 1958.
A submarine chaser or subchaser is a type of small naval vessel that is specifically intended for anti-submarine warfare. They encompass designs that are now largely obsolete, but which played an important role in the wars of the first half of the 20th century. 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 BYMS class was a class of wooden motor minesweepers, part of the United States Navy YMS-1 class minesweepers. One hundred fifty ships destined for the United Kingdom were launched from 1941 to 1943.
USS Turkey (AMS-56/YMS-444) was a YMS-135 subclass of YMS-1-class minesweepers built for the United States Navy during World War II.
The YMS-1 class of auxiliary motor minesweepers was established with the laying down of YMS-1 on 4 March 1941. Some were later transferred to the United Kingdom as part of the World War II Lend-Lease pact between the two nations. One ship eventually made its way into the Royal Canadian Navy postwar.
USS Magpie (AMS-26/YMS-400) was a YMS-1-class minesweeper of the YMS-135 subclass built for the United States Navy during World War II.
USS Bond (AM-152) was an Admirable-class minesweeper built for the United States Navy during World War II and in commission from 1943 to 1945. In 1945, she was transferred to the Soviet Union and served after that in the Soviet Navy as T-285 and as BRN-37.
Auxiliary motor minesweepers were small wood-hulled minesweepers commissioned by the United States Navy for service during World War II. The vessels were numbered, but unnamed. The auxiliary motor minesweepers were originally designated yard minesweepers (YMS) and kept the abbreviation YMS after being re-designated. The type proved successful and eventually became the basis for the AMS type of United States Navy minesweeper.
USS Brambling (AMS-42/YMS-109) was a YMS-1-class auxiliary motor minesweeper acquired by the U.S. Navy for the task of removing mines from water that had been placed there to prevent ships from passing.
Coastal Forces was a division of the Royal Navy established during World War II. It consisted of small coastal defence craft which the Navy designated with names such as: Motor Launch, High Speed Launch, air-sea rescue, Motor Gun Boat and Motor Torpedo Boat. It did not include landing craft, trawlers or purpose-built minesweepers. Other Navies operated equivalent boats, but classified and named them somewhat differently.
Naval trawlers are vessels built along the lines of a fishing trawler but fitted out for naval purposes; they were widely used during the First and Second World Wars. Some, known in the Royal Navy as "Admiralty trawlers", were purpose-built to naval specifications; others were adapted from civilian use. Fishing trawlers were particularly suited for many naval requirements because they were robust vessels designed to work heavy trawls in all types of weather, and had large clear working decks. A minesweeper could be created by replacing the trawl with a mine sweep. Adding depth charge racks on the deck, ASDIC sonar below, and a 3-inch (76 mm) or 4-inch (102 mm) gun in the bow equipped the trawler for anti-submarine duties.
The Adjutant-class auxiliary motor minesweepers were built for the United States Navy throughout the 1950s and 1960s, even as late as 1978. Most were loaned to foreign countries under the Military Defense Assistance Pact, with only 24 actually commissioned by the US Navy, with 13 of those eventually being transferred to foreign nations as well. Initially classified as auxiliary motor minesweepers (AMS), on 7 February 1955, they were reclassified as coastal minesweepers (MSC).
Project Hula was a program during World War II in which the United States transferred naval vessels to the Soviet Union in anticipation of the Soviets eventually joining the war against Japan, specifically in preparation for planned Soviet invasions of southern Sakhalin and the Kuril Islands. Based at Cold Bay in the Territory of Alaska, the project was active during the spring and summer of 1945. It was the largest and most ambitious transfer program of World War II.
South Coast Shipyard was a shipbuilding company in Newport, California. To support the World War II demand for ships South Coast Shipyard built: minesweepers, Torpedo Boats, Submarine chasers, & Air-sea rescue boats. South Coast Shipyard was opened in 1938 by Walton Hubbard. After World War II the shipyard continued to build ships for the US Navy till 1955. The shipyard was located at 2300 Newport Boulevard, Newport, California. The shipyard closed in 1963.
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.
Weaver Shipyards, also called Weaver Brothers Shipyards was a shipyard in Orange, Texas on the Sabine River. The shipyard opened in 1897. The shipyard was founded by Joe Weaver and his son as Joseph Weaver and Son Shipyard. Joe Weaver was L.E. Weaver, known as Ed Weaver. In 1898 Levingston Shipbuilding Company founder, George Levingston purchased major shares of Joseph Weaver and Son Shipyard. Weaver Shipyard's early work was the construction work for Galveston Navigation District building barges. The yard was also active in building and repairing tugboats. In 1930 Joseph Weaver died and a new family partnership was made, L.E. Weaver and his son. Ed Weaver's son was L.A. Weaver. In 1941 Ed Weaver died and L.A. Weaver changed the shipyard to Weaver Shipyards. Weaver Shipyards became a partnership of several a Weaver family members.
