i thought they carried around warhead.... shelves in the ammo sections of the ship and just replaced the tip of the missiles a lot of stuff works like this for plane launched cruise missiles/glide bombs it should be the same for missiles if a tomahawk is too heavy even just the warhead then of course they would need a small crane but most military boats have cranes  it all depends on whether you can screw on or off the warhead easily and if the ships leave shore carrying nuclear warheads and spare warheads or not  if they dont it seems like s huge strategic vulnerability  imagine getting nuked by icbms what is the navy meant to do, spend a week sailing back to the american ports then refit their missiles one by one? in the destroyed dry docks?  > just you wait till i put nukes on my missiles then youll be sorry! just you wait!!
