Well, they would certainly not order the ship as drawn now, as there are quite some issues with it
First of all, I count 5 different gun calibers, each requiring separate fire control, spotting, training and logistics. The fire control would be hard pressed to do it's job, as most antenna's are blocked by at least one other system.
I would also have to dive into the workings of your powerplant, but I am certain about one thing: as drawn, your ship looks extremely blocky with an very short stern and even an filled up bow. Especially that bow I cannot find reason for the bulbous section, such a shape would only increase slamming in heavy weather in my opinion.
