Hm, this isn't intuitive to me. How could a rocket that was designed to withstand the pressures and conditions of space not be able to take some salt water? And what about just adding a layer of coating that would protect it?
Just guessing: In space the pressure comes from inside, in water from outside; it is easier to protect in one direction than in both. In space the pressure difference is at most one atmosphere, in water it depends on how deep you submerge. The salt water also attacks the metal chemically.
