Heavy guns fit an LHD more easily than fixed-wing aviation

Is a battleship-LHD hybrid necessarily a bad idea?

Not necessarily for helicopters and guns, but fixed-wing aircraft and missile launchers create much harder deck-layout and blast-management problems.

A gun-heavy helicopter assault ship may work better than the battleship-LHD label suggests. The design becomes more difficult when fixed-wing aviation is added because aircraft and weapons must share the operating deck. Missile launchers create another deck-flow problem, although placing them far enough out on sponsons can reduce the conflict. The workable combination is therefore helicopters and guns, with fixed-wing aircraft and missile exhaust imposing the harder constraints.
