So far, the big problem with railguns, is the rails wearing out after just a few shots.
An Iowa Class hull would make an adequate platform for mounting several of these weapons.
Didn’t know that.
I thought the big drawback was the power required...and that there would be no “wear”, because the ordinance never actually touched the rail, it was ejected on a mag-lev concept suspended in air even by a very, very tiny amount and then a wave of electromagnetic energy pulsing down a linear path would push the projectile in front of it.
I haven’t been following it that closely for a while, so you could be right and my understanding could be out of date.
