In a nuclear ramjet the vehicle flies so fast the air entering the engine intake needs no compression and flows directly through the reactor core. Fission superheats and expands the air which ...

to look at the feasibility of a nuclear-powered ramjet. Named Project Pluto, the eventual goal was to prototype a hypersonic engine for what was called the Supersonic Low Altitude Missile—or ...

complementing its Triomphant-class submarines that are armed with M51 nuclear ballistic missiles. The ASMPA-R is a supersonic cruise missile powered by a kerosene-fueled ramjet engine, a ...

Mounted on top of a railroad car, it marked the world's first nuclear ramjet engine when it came to life for just a few seconds. Three years later, the U.S. tested the Tory II-C, which was able to ...

Cattle and sheep graze over the vast domain of the Atomic Energy Commission’s Nevada Test Site northwest of Las Vegas, which saw its last nuclear explosion in 1958 when the U.S. and Russia ...
