Well, if they’d developed it properly, it could have been hell on wheels against other ships as well as ground targets as well as possibly against many air targets. Instead, the dev program was run by morons - morons who deleted the gun’s ability to fire regular 155mm rounds.
Or they could have already gone with railguns. But the Navy canceled the (very minimal) funding for researching WB series of fusion reactors needed to power the railguns (since nuclear fission is a no-no now) so they could do diversity and integration and now this is where we’re at.
But the Muzzies are well funded and armed. I’m surprised out military has anything short of queers - apologies to the good and bad warrior class.
