The 375 mm ASW rocket family is an ahead-throwing anti-submarine rocket system developed by Bofors. The system has three types of launcher with either two, four, or six barrels, and entered service in the 1950s. Sweden used the four-barreled system on the Halland and Visby-class destroyers. France built the four-barrelled system under licence then developed the six-barrel system and used it on many classes of warship including T 47 and T 53-class destroyers and A 69-class avisos (corvettes). The Netherlands used it in the Friesland-class destroyers. It was also used by Royal Malaysian Navy on the Kasturi-class corvettes before they removed it from the ships. Indonesia use it on its three Fatahillah-class corvettes and Brazil on six Niterói-class frigates, all of which are still in service. The rocket system is also being used by the Turkish Burak-class corvette's which are all ex-D'Estienne d'Orves-class A69 type aviso corvettes, mainly designed for coastal anti-submarine defense and ocean escort missions.
