The Tacoma class was a class of 96 patrol frigates which served in the United States Navy during World War II and the Korean War. Originally classified as gunboats (PG), they were reclassified as patrol frigates (PF) on 15 April 1943. The class is named for its lead ship, Tacoma, a Maritime Commission (MARCOM) S2-S2-AQ1 design, which in turn was named for the city of Tacoma, Washington. Twenty-one ships were transferred to the British Royal Navy, in which they were known as Colony-class frigates, and twenty-eight ships were transferred under Lend-Lease to the Soviet Navy, where they were designated as storozhevoi korabl, during World War II. All Tacoma-class ships in US service during World War II were manned by United States Coast Guard crews. Tacoma-class ships were transferred to the United States Coast Guard and various navies post-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 SC-255, sometimes styled as either Submarine Chaser No. 255 or S.C.-255, was an SC-1-class submarine chaser built for the United States Navy during World War I. Like most members of her class, she was not named and known only by her designation.
BRP Datu Marikudo (PS-23) was a Malvar-class corvette of the Philippine Navy. She was originally built as USS PCE(R)-853, a PCE(R)-848-class patrol craft for the United States Navy during World War II. She was renamed USS Amherst on 15 February 1956, namesake of both Amherst, Massachusetts and Amherst, Ohio. In February 1970, Amherst was decommissioned and transferred to South Vietnam for service in the Republic of Vietnam Navy as RVNS Vạn Kiếp II (HQ-14). She remained in South Vietnamese service until the collapse of that country in 1975. Vạn Kiếp II was one of several ships that fled from South Vietnam to the Philippines. She was then commissioned into the Philippine Navy on 5 April 1976 and named in honor of Datu Marikudo. Along with other World War II-era ships of the Philippine Navy, Datu Marikudo was considered one of the oldest active fighting ships in the world until her decommissioning.
USS PGM-18 was a PGM-9-class motor gunboat built for the United States Navy during World War II. She was built and originally commissioned as USS PC-1255, a PC-461-class submarine chaser, and was decommissioned and converted in late 1944. USS PGM-18 struck a mine off the coast of Okinawa in April 1945; 13 men lost their lives when PGM-18 sank.
The PGM-39-class gunboats, designated Patrol Gunboat, Motor by the United States Navy were a class of fifty nine gunboats constructed in various shipyards from 1959–1970. The design was based on the United States Coast Guard Cape-class cutter design with a five-foot (1.5 m) hull extension. It was specifically designed for the U.S. Military Assistance Program and was used by the navies of The Philippines, Indonesia, South Vietnam, Thailand, Burma, Ethiopia, and Ecuador.
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.
HMS Montserrat (K586) was a Colony-class frigate of the United Kingdom that served during World War II. She originally was ordered by the United States Navy as the Tacoma-class patrol frigateUSS Hornby (PF-82) and was transferred to the Royal Navy prior to completion.
The PCE-842-class patrol craft escort was a United States Navy (USN) ship class of submarine chasers designed during World War II. The PCE-842-class was the only class ever designated by the USN as the "patrol craft escort" (PCE) type. The PCE design was derived from the 180-foot (55 m) Admirable-class minesweeper to complement 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 but with a less powerful engine also much slower; however, because of its larger size, the PCE was able to undertake longer-range tasks over PC-461-class vessels. The USN envisaged the PCE as enabling PCs and smaller vessels to undertake coastal patrols without being called-upon as often to perform open ocean and convoy escort duties, while simultaneously freeing-up some larger vessels - such as destroyer escorts and destroyers - from convoy ASW duties. The PCE-482-class had a standard crew complement of 99 officers and men. The class would ultimately see 68 total vessels built, serving with multiple navies around the world.
