A nuclear powered cruise missile...
WTF for? No jet fuel?
See Project Pluto: https://en.wikipedia.org/wiki/Project_Pluto
The idea is that you get unlimited range and an (almost) unlimited loiter time. If this would ever work, they could be cruising 24x7 and then sent in for surprise attacks. Didn’t work for us when we tested years ago. Too dirty with the radiation. Nuclear engines are just flying dirty bombs waiting for an accident.
1) No jet fuel.
2) Extremely long range.
3) Extremely fast.
4) Extremely 'dirty' in the radiological sense.
We built a series of nuclear ramjet engines in the 1950's and early '60s, intended to propel a large cruise missile. Back when we were capable of 'thinking big'. They work. The project was canceled because chemically fueled ballistic missiles are cheaper and easier to build and deploy. The laws of physics haven't changed; the state of the art in materials has greatly improved. I'm not surprised the Soviets Russians are trying it. If that's what they're doing.
because it could literally stay airborne for days or longer and able to strike any spot on earth
