A ramjet, or athodyd (aero thermodynamic duct), is a form of airbreathing jet engine that uses the forward motion of the engine to produce thrust. Since it produces no thrust when stationary (no ram air) ramjet-powered vehicles require an ass ...

Etymology
The Rigel missile was named after Rigel, the brightest star in the constellation
Orion.
Development
In 1946 the US Navy sanctioned development of the Rigel missile as a sub-launched supersonic weapon to attack enemy shores, in parallel with development of the subsonic SSM-N-8 Regulus.
The SSM-N-6 was to be launched by means of 4 rocket boosters and a catapult, with two ramjets for the cruise mode of the flight.
Several Rigel test articles were built to test the planned ramjet system for the Rigel missile. They had a single ramjet and a single rocket booster.
Subsequently, scaled-down Flight Test Vehicles (FTVs) were built with a configuration similar to the full-scale missile, and the first FTV launch occurred in May 1950. Unfortunately, plans to build the SSM-N-6 missiles were cancelled because the failure of FTV flight tests, but also due to the fact that Rigel posed a problem for submariners by requiring a longer launch rail on submarines than the
SSM-N-8 Regulus
The SSM-N-8A Regulus or the Regulus I was a United States Navy-developed ship-and-submarine-launched, nuclear-capable turbojet-powered second generation cruise missile, deployed from 1955 to 1964. Its development was an outgrowth of U.S. Navy ...
