The crane is too modern, it belongs in the late 30s. The catapult is too big and that plane is for 1942 and later. I suggest you use the more compact catapult from the Colorado, and the boat handling crane. You wont have enough space to have two catapults on the side. Put the catapult in the middle, and then put the cranes, one on each side where the aft 76mm gun is now, and then move the gun forward. The viewing slit looks wrong. It's not a porthole, but small holes in an armored conning tower. You should have two of them, 3 pixels tall and 4 pixels long.
What about only having one catapult?
