Regulus I
The SSM-N-8A Regulus or the Regulus I was a US Navy ship-and-submarine-launched, nuclear-capable turbojet-powered second generation cruise missile, deployed from 1955 to 1964 by the Chance Vought Aircraft Company. When the missiles were deployed they were launched from a rail launcher, and equipped with a pair of Aerojet JATO bottles on the aft end of the fuselage.
