LOL this makes me think like when building a house.. Mrs. Navy is doing the walk through and.....
ohhhh we can put a SAM right here and over there,
a belt feed rotary cannon here,
oh oh oh... in that corner can be extra torpedo storage
And that aint all yet, here in the basement, we must have that screen door that we saw on the flex seal commercial !!
You forgot the part where:
Mrs. Navy: "A belt feeder cannon over here. Let's move that one from over there to this spot."
Naval Engineer: "Umm, that will end up being an interference with this system over here, we can't do that."
Mrs. Navy: "Well, make it work, that cannon needs to be on this side."
Naval Engineer: "Ummmmm, OK, give me a week to see if we can do it. Off-the-cuff, it will take about 4 weeks of engineering time and 1.6 million dollars in changes to the framing after confirming with structural..."
Mrs. Navy: "Noted, though I expect it done in half that time and at 1/3 of the cost..."
(Time passes)
Naval Engineer: "OK, it took us two weeks of design time (a couple of all-nighters), but we were able to reroute this system to the back compartment to make room for the cannon. We were able to cut some corners, but we were only able to get it down to 1.1 million dollars to make the changes."
Mrs. Navy: "No. No. No. Now that I see it, it's all wrong. This won't do at all. Let's go ahead and put it over there instead."
Naval Engineer: "Ummm, Mame? Isn't that where it was before?"
Mrs. Navy: "What? I don't know. Get it done, son!"
Naval Engineer (Under his breath): "And this is why they didn't used to allow women on the ship back in the old days."
Mrs. Navy: "What did you say?"
Naval Engineer: "I said this is why they didn't route a plenum box on the ship back in the old days."
Mrs. Navy: "Oh. OK. Carry on."
