We need fighting ships, not futuristic runs of 3 in a class, but real fighting destroyers and cruisers capable of operating pilotless craft to expand capabilities. Carriers that can operate drone and manned aircraft. Weapons that can reach out and destroy a target without them even knowing we are in the neighborhood.
The Chinese have a lot of manpower to use for their navy, and while the US doesn't, it should be developing the technology to negate that manpower and keep the Chinese navy in check with drones of it's own.
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.
