Not only what PzGen said by what about storage for equipment for the LCAC.

When you really think about it, the BBG shouldn't use any planes, but just a platform for some AH-1s and a seahawk or 2.. Think about it, your not going to have huge naval battles any more! so just how many Harpoons are needed.

What you need are Missles, AAs and Tomhawks. Look at those 4 retired Ohio's that the Navy did, They had to take the Tridents out by treaty and the Navy replaced them with 150 Tomhawks per sub. This is where the fire power is!

Not in 16" guns
