Mark 32 surface vessel torpedo tubes (Mk 32 SVTT) is atorpedo launching system designed for theUnited States Navy.[2]
The Mark 32 has been the standard anti-submarine torpedo launching system aboard United States Navy surface vessels since its introduction[3] in 1960,[citation needed] and is in use aboard the warships of several other navies.[3]
During theFRAM Program,Fletcher,Allen M. Sumner andGearing-classdestroyers were modernized and fitted with two Mark 32 torpedo tubes on each side of their midship. The torpedo tubes' service extended to multiple other countries such as Mexico, South Korea, Taiwan, Turkey, Egypt and many more due to the fact that decommissioned American ships were bought or transferred over to them throughout the years, notablyOliver Hazard Perry-classfrigates.
Japan uses the HOS-301 torpedo tubes which are redesignated version of the Mark 32.
Most versions (referred to as modifications or mods) are triple-tube sets that can be rotated or trained to face a target.[3] The exception is the Mod 9 sets, which only have two tubes and are fixed in position.[3] The Mark 32 can fire 12.75-inch (324 mm) torpedoes of theMark 44,Mark 46,Mark 50 (from the Mod 17 tubes onwards),[3][4] andMark 54[citation needed] designs, and can be modified to use other torpedoes (such as theMU90 Impact aboardRoyal Australian Navy frigates, orRoyal Navy units usingSting Ray torpedoes).[5][6] The tubes are designed to be fired remotely, but manual firing controls are fitted as a backup to all but theSpruance-class destroyer's Mod 15 sets, as all aspects of the tubes' operation are controlled remotely.[3] The launch is powered by compressed air[3] in a rear flask, which doubles as each tube'sbreech, and the torpedoes arefire-and-forget weapons.[citation needed]
The launcher can be made fromfibreglass, or with a fibreglass liner encased in metal.[3] The tubes were designed to be weatherproof and capable of storing torpedoes for long periods, but this is only practical with regular maintenance.[citation needed] Each triple-tube set weighs around 2,230 pounds (1,010 kg) unloaded, with variations between mods.[3]
