Sounds like a challenge. Smile

I bet an answer could be found in coatings before you need to get to cold plasma armatures. There are some low friction, arc-resistance coatings in the electrical industry today like cadmium oxide.

I believe that is exactly what the naval railguns will do. It'll still be cheaper than a bunch of cruise missiles or antiship missiles.

The Navy probably doesn't mind because their battleship guns only had a barrel life of a few hundred rounds. Barrel wear is a known issue for them.
