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 "A69" D'Estienne d'Orves-class avisos (corvettes).

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.
