Nuclear Katyusha and Nuclear Verne Gun






"The core idea for the nuclear verne launch gun is simple though dramatic: Dig a kilometers deep shaft—a salt layer would be easiest to penetrate (some exist 3.5 kilometers thick) —build at the bottom a giant shell, from components lowered into place, layer by layer enclosing its internal payloads with external structures (such as a supporting sabot) and sealing the unit to flight-ready status. Place sets of guide rails around the perimeter of the shaft with ‘slippers’—metal contact shoes—touching the rails from the edges of the Wang Bullet. Finally, after all is in readiness, pump reaction mass through an access shaft under the sabot into a prepared chamber and place a thermonuclear explosive device in the midst of the reaction mass."

"The Nextbigfuture nuclear launch gun has been described several times. It is a one pulse variant of a project orion external pulse propulsion system. It is simple though dramatic: Dig a kilometers deep shaft—a salt layer would be easiest to penetrate (some exist 3.5 kilometers thick) —build at the bottom a giant shell, from components lowered into place, layer by layer enclosing its internal payloads with external structures (such as a supporting sabot) and sealing the unit to flight-ready status. Place sets of guide rails around the perimeter of the shaft with ‘slippers’—metal contact shoes—touching the rails from the edges of the Shell. Finally, after all is in readiness, pump reaction mass through an access shaft under the sabot into a prepared chamber and place a thermonuclear explosive device in the midst of the reaction mass. A 150 kiloton version would not violate the nuclear test ban treaties which permit underground nuclear explosions up to 150 kilotons. About 85% of heat energy of the nuclear explosion should be converted into kinetic energy to launch the roughly 3500 ton shell to over escape velocity."

I have serious doubts about these plans, both physically and politically. The so-called Pascal - b test did not, I repeat DID NOT launch a manhole cover to escape velocity, as everyone including whatever jerk runs the wikipedia page seems to think. Anything accelerated that fast would be destroyed, and it was not accelerated that fast anyway. But, these ideas have some merit. This is worth considering further.
