The RUR-4 Weapon Alpha (originally Weapon Able) was an American naval ahead-throwing ASW rocket launcher. It was designed between 1946 to 1950 and was installed on warships from 1951 to 1969. It was designed to attack enemy submarines without requiring the attacking ship to be located directly above the submarine being attacked.
