A nuclear salt-water rocket is a type of rocket designed by Robert Zubrin that would be fueled by water bearing dissolved salts of plutonium or U235. These would be stored in tanks that would prevent a critical mass from forming by some combination of geometry or neutron absorption. The rocket would be powered by a nuclear-thermal reaction when the water was injected into a reaction chamber.

Calculations show that this rocket would have both very high thrust and a very high specific impulse, a rare combination of traits in the rocket world.
