I will let CDR Salamander take it from here:
Just for fun, because I know the Church of the LCS can't stand them - let us look at the FFG-7 class of ships. There were, shocker, 55 of them built in the United States.
Would those who came before us have let FFG-7 (USS OHP actual commissioned in 1977) through FFG-31 (USS STARK commissioned in 1982) be bought and paid for without even knowing SM-1, Harpoon, MK-46, SLQ-32, or helicopters could even work? Wait .... oh that's right; they actually built ships based on sound practices with weapons systems that were known to work before putting them on a new class of warship. BTW, when did we decide that hope was a plan? I think I slept through that class; my bust.
