We need hulls in the water and I think more subs are needed and not necessarily nuke boats. With current technology we could probably build one hell of a good electric boat and probably a lot cheaper than a nuke version.
More hulls is the answer, but they have to be the 'right' hulls. The LCS was a total disaster and the contract given to manufacture was to bolster a re-election ticket.
The Zumwalts are a good start, but killed way to premature and without the LRLAP ammunition totally useless with the guns it has.
