Some time ago, I read an article on This is Rocket Science. It talked about a crazy nuclear powered rocket and was illustrated with the image to the right:

Back in the mid 1950's, nuclear powered cruise missiles were being studied and in 1957, development was initiated as Project Pluto. The reactor for the missile was to be developed by the Lawrence Radiation Laboratory, with the ramjet being built by Marquadt. Ling-Temco-Vought was awarded the contract to develop the airframe for the missile itself, which was known as SLAM (Supersonic Low-Altitude Missile).

And I thought to myself (and anyone else in ear-shot at the time) that I had to have a go at building one!

I built this up in Rocksim. It seems stable and an E9 should push it to about 1,000' and an F21 to about 1,900'

If the weather is on our side this weekend, it should get a launch!
