A colleague recently clued me in on a post-WW II weapon of which I’d never heard – The Flying Crowbar. Oddly Historical’s Andrew Kincaid covered it in an undated post (which seems peculiarly apropos given the blog’s title):
At the core of this ultra-durable doomsday weapon was a simple concept: the ramjet. It has been the working concept behind jet engines sine the first prototypes in the 1930s. Air is sucked into a nozzle, where it is then heated. the air expands, and blows out the rear nozzle of the craft, thus providing propulsion. In most jets, the heating is achieved by burning hydrocarbon fuels. In The Flying Crowbar, an unshielded nuclear reactor would provide the heat. This gave the advantage of an almost limitless operational lifespan. As long as the nuclear core could undergo fission, the Flying Crowbar could sow death and destruction.
One distinct disadvantage of the system was the very thing that gave it its advantage–the nuclear reactor. Most nuclear reactors are quite sanely tucked behind layers and layers of concrete, because they have a tendency to spew a lot of radiation. The Flying Crowbar’s reactor would be housed in a missile the size of a locomotive, flying at a low altitude over friend and enemy alike. Planners predicted that the shockwave from the weapon passing overhead might be enough to kill people on the ground. If that didn’t do it, radiation spewing out of the reactor would finish the job.
And then combine this with a psychotic artificial intelligence with a grudge against its creators? Ex Machina (2015) would have nothing on this demon from hell.
NationStates also has some information.
