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 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.
USS Fletcher (DD-992), the thirtieth Spruance-class destroyer, was part of the first major class of United States Navy surface ships to be powered by gas turbines. She was commissioned in July 1980 and was deployed mainly in the western and southern Pacific, but also voyaged to the Indian Ocean and Persian Gulf. She was the second ship in the U.S. Navy to bear this name but the first to be named after Admiral Frank Friday Fletcher, AndFrank Jack Fletcher. After her decommissioning in 2004, she was sunk in a torpedo test exercise in 2008.
The RUM-139 Vertical-Launch Anti-Submarine Rocket is an anti-submarine missile in the ASROC family, currently built by Lockheed Martin for the U.S. Navy.
The Ikara missile was an Australian ship-launched anti-submarine missile, named after an Australian Aboriginal word for "throwing stick". It launched an acoustic torpedo to a range of 10 nautical miles (19 km), allowing fast-reaction attacks against submarines at ranges that would otherwise require the launching ship to close for attack, placing itself at risk. By flying to a distant target, the engagement time was dramatically shorter than provided by short-range weapons, giving the target less time to respond.
The Delhi-class destroyers, also known Project 15 are a class guided-missile destroyers of the Indian Navy. Three ships of this class are in active service. The Delhi-class vessels were the largest vessels to be built in India at the time of their commissioning. The ships were built by Mazagon Dock Limited (MDL) at a cost of ₹750 crore each.
Garcia-class frigates were United States Navy warships. These frigates were originally ocean escorts bearing the hull classification DE until 1975. The ships were commissioned between 1964 and 1968 and decommissioned between 1988 and 1990.
An anti-submarine weapon (ASW) is any one of a number of devices that are intended to act against a submarine and its crew, to destroy (sink) the vessel or reduce its capability as a weapon of war. In its simplest sense, an anti-submarine weapon is usually a projectile, missile or bomb that is optimized to destroy submarines.
The California class was a pair of nuclear-powered guided-missile cruisers operated by the United States Navy between 1974 and 1998. Other than their nuclear power supply and lack of helicopter hangars, ships of the California class were comparable to other guided-missile cruisers of their era, such as the Belknap class. The class was built as a follow-up to the nuclear-powered Long Beach, Bainbridge, and Truxtun classes. Like all of the nuclear cruisers, which could steam for years between refuelings, the California class was designed in part to provide high endurance escort for the navy's nuclear aircraft carriers, which were often limited in range due to their conventionally powered escorts continuously needing to be refueled.
The UUM-125 Sea Lance, known early in development as the Common ASW Standoff Weapon, was to be an American standoff anti-submarine missile, initially intended to carry a W89 thermonuclear warhead. It was conceived in 1980 as a successor to both the UUM-44 SUBROC and RUR-5 ASROC anti-submarine missiles. The Sea Lance was to be available in two versions, known as UUM-125A and RUM-125A. The former would be a submarine-launched version, the latter surface-launched. It was cancelled in 1990 as its importance was obviated by the collapse of the Soviet Union.
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 People's Liberation Army Navy (PLAN) is the naval branch of the People's Liberation Army (PLA), the armed forces of the People's Republic of China. The PLAN force consists of approximately 250,000 men and over a hundred major combat vessels, organized into three fleets: the North Sea Fleet, the East Sea Fleet, and the South Sea Fleet.
The Belknap-class cruiser was a class of single-ended guided-missile cruisers built for the United States Navy during the 1960s. They were originally designated as DLG frigates, but in the 1975 fleet realignment, they were reclassified as guided missile cruisers (CG).
The Metel Anti-Ship Complex is a Soviet family of anti-submarine missiles. There are different anti-submarine variants ('Metel') for cruisers and frigates, and a later version with a shaped charge ('Rastrub') that can be used against shipping as well as submarines.
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.
An anti-submarine missile is a standoff anti-submarine weapon, often a specialized variant of anti-ship missile. Anti-submarine missile usually include a jet or rocket engine and a warhead aimed directly at a submarine. In these missiles, a torpedo or a depth charge is used as a warhead. The anti-submarine missile can be either a cruise missile or a ballistic missile.
The Audace-class destroyers were two guided missile destroyers built for the Italian Navy during the Cold War. An improvement of the Impavido class, these ships were designed for area air defence and also had a heavy gun armament. They were fitted with contemporary American radars and sonars, but also, as the next Italian ships, all the modern weapons made by Italian industry of the time, such torpedoes, helicopters and guns. Also some indigenous radars were fitted.
The CY-1 is a Chinese anti-submarine rocket carried on a variety of surface platforms, including the Luda class missile destroyers and Jiangwei class missile frigates. A series of CY ASW missiles have been developed based on CY-1. To date only a small number of CY-1 is known to have been produced and deployed on trial basis, despite the fact that it had first appeared on the defense exhibitions held in China in the late 1980s.
The Restigouche-class destroyer was a class of seven destroyer escorts that served the Royal Canadian Navy and later the Canadian Forces from the late-1950s to the late-1990s. All seven vessels in the class were named after rivers in Canada.
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.
