Why not just go for two Mark 26 Mod 2 launchers? Granted, you'll carry fewer missiles (128 instead of 160) and you'll fire them somewhat slower (24 shots per minute instead of 30), but those missiles can quite a bit larger (2200lb instead of 1500lb, 14.75” x 200” instead of 13.5” x 186.45”) and it'll simplify the layout tremendously.
Thanks Thiel I think I will push the building year a couple of year forward, so I an use the Mark 26 mod 2. I had a bit thinking and decided that instead go my own way a should be a bit inspirited of California but do it a bit different!
So the Mark 23 are going to be replaced by Mark 26 Mod 2
This is how I am thinking now, all thing on-board is just wild guesting!
