Bob- Your ship's pump only costs .5 units, so you DO get the extra 25 rounds. I'm at work atm, so I cant look up the exact wording of the rule to post, but I am positive that carrier pumps cost .5 units as per the rules. I'll try to remember to look it up when I get home. I'm sure of it because I looked it up for my Belleau Wood, and was very surprised when I read it, since I had originally thought my pump was going to cost me a full unit. Have you thought of adding a depression mechanism for your stern gun(s)? It's an idea Eric Noble and I had been kicking around when he was talking about building a Lexington.
