Regulus Missiles in Action
Regulus was first deployed by the US Navy in 1955 in the Pacific onboard the cruiser USS Los Angeles (CA-135). By 1956 the surface launched Regulus was deployed onboard specially designed diesel powered submarines. The USS TUNNY (SSG-282) and USS BARBERO (SSG-317) were our Nations first nuclear deterrent patrol submarines. They were joined by three additional Regulus submarines, USS GRAYBACK (SSG-574), USS GROWLER (SSG-577), and the nuclear powered USS HALIBUT (SSGN-587). Regulus submarine nuclear deterrent patrols ceased in 1964.
