many destroyers (including world war 2) have only forward main guns (usually 1 or 2). I can only speak from my experience playing naval ship games. Destroyers are very small but nimble ships. if you need to fire from aft guns, you already lost. Space is precious, better to have something like a helipad back there than another gun you'll never need, in my limited opinion on naval ships.
