BB's, some personnal idea's for the 1947+ version
- twin 76mm location
- maybe replacement of the ageing seaplane by the early newer helicopters around 1948 ? (maybe you can delete the catapult by 1948-1952 !!!)
- for the 20mm mount, you can delete almost all gun, except a very small handfull, ideally 2 or 3 mounts toward forward & 2 or 3 mounts toward aft superstructure (for a full better arc of fire).
