The RUR-5 ASROC is an all-weather, all sea-conditions anti-submarine missile system. Developed by the United States Navy in the 1950s, it was deployed in the 1960s, updated in the 1990s, and eventually installed on over 200 USN surface ships, specifically cruisers, destroyers, and frigates. The ASROC has been deployed on scores of warships of many other navies, including Canada, Germany, Italy, Japan, Taiwan, Greece, Pakistan and others.
The Fleet Rehabilitation and Modernization (FRAM) program of the United States Navy extended the lives of World War II-era destroyers by shifting their mission from a surface attack role to that of a submarine hunter. The FRAM program also covered cruisers, aircraft carriers, submarines, amphibious ships, and auxiliaries. The United States Coast Guard also used this term in the 1980s for the modernization of its Hamilton-class cutters.
The 46 Knox-class frigates were the largest, last, and most numerous of the US Navy's second-generation anti-submarine warfare (ASW) escorts. Originally laid down as ocean escorts, they were all redesignated as frigates on 30 June 1975, in the 1975 ship reclassification plan and their hull designation changed from 'DE' to 'FF'. The Knox class was the Navy's last destroyer-type design with a steam turbine powerplant.
The Gearing class was a series of 98 destroyers built for the U.S. Navy during and shortly after World War II. The Gearing design was a minor modification of the Allen M. Sumner class, whereby the hull was lengthened by 14 ft (4.3 m) at amidships, which resulted in more fuel storage space and increased the operating range.
The Type 82 or Bristol-class destroyer was a 1960s guided missile destroyer design intended to replace County-class destroyers in the Royal Navy. Originally eight warships were planned to provide area air-defence for the four planned CVA-01 aircraft carriers. They would also have been able to operate independently as modern cruisers "East of Suez".
The Allen M. Sumner class was a group of 58 destroyers built by the United States during World War II. Another twelve ships were completed as destroyer minelayers. The class was named for Allen Melancthon Sumner, an officer in the United States Marine Corps. Often referred to as simply the Sumner, this class was distinguished from the previous Fletcher class by their twin 5-inch/38 caliber gun mounts, dual rudders, additional anti-aircraft weapons, and many other advancements. The Allen M. Sumner design was extended 14 feet (4.3 m) amidships to become the Gearing class, which was produced in larger numbers but did not see significant service in World War II.
The Gyrodyne QH-50 DASH is a small drone helicopter built by Gyrodyne Company of America for use as a long-range anti-submarine weapon on ships that would otherwise be too small to operate a full-sized helicopter. It remained in production until 1969. Several are still used today for various land-based roles.
The Atago class of guided-missile destroyers in the Japan Maritime Self-Defense Force is a modified version of the Kongō class equipped with the Aegis Combat System.
The Murasame-class destroyer is a class of destroyers, serving with the Japan Maritime Self-Defense Force (JMSDF). This is the first class of the second-generation general-purpose destroyers of the JMSDF.
The Tachikaze-class destroyer was a second generation guided missile destroyer class, formerly in service with the Japan Maritime Self-Defense Force (JMSDF). The ships of this class have had successive improvements after their completion, especially to their C4I systems. These air-defense warships are the natural successor to the first generation air-defense ship, the Amatsukaze-class destroyer, and they were in turn, followed by newer air-defense ships, the Hatakaze class.
The Yamagumo class are vessels of the Japanese Maritime Self-Defense Force, usually classified as a destroyer, but due to their relatively light displacement, in other sources as a destroyer escort. This class is the successor of the Akizuki class.
The Abukuma-class destroyer escort is the general-purpose destroyer escort of the Japan Maritime Self-Defense Force. It is the successor of the earlier Yūbari class.
The Chikugo-class destroyer escort was a class of destroyer escorts built by the Japanese Maritime Self-Defense Force as the successor of the Isuzu class, with the same ASW mission. This class was followed by JDS Ishikari. This is the first Japanese destroyer escort class to carry ASROC anti-submarine missiles.
USS Henderson (DD-785) was a Gearing-class destroyer of the United States Navy, the second Navy ship of that name, and the first named for United States Marine Corps Major Lofton R. Henderson. The previous Henderson was named for Marine Corps Commandant Archibald Henderson.
The Dealey-class destroyer escorts were the first post-World War II escort ships built for the United States Navy.
JDS Isuzu (DE-211) is the lead ship of the Isuzu-class destroyer escorts of the Japan Maritime Self-Defense Force (JMSDF).
JDS Mogami (DE-212) is the second ship of Isuzu-class destroyer escort of Japan Maritime Self-Defense Force (JMSDF).
JDS Minegumo (DD-116) was the lead ship of Minegumo-class destroyers.
JDS Natsugumo (DD-117) was the second ship of Minegumo-class destroyers.
Multiple 32 cm torpedoes are in use by the Japan Maritime Self-Defense Force, following the adoption of the standard in the second half of the 20th century.
