At one point in the 1960's I think we once had 26 carriers active and only 3 carrier piers at NOB NORVA. The two east coast carrier yards are there as well. Re-open, upgrade, modify, Mayport as a homeport or develop another east coast homeport to place two carriers.
I think most of us by now have seen the pictures of 4 & 5 carriers at NOB NORVA. You can also see the carriers from I-64 and the Norfolk Naval Shipyards from the southern by-pass. So much for security huh?
As for how long can a nuclear vs conventional actually deploy before needed downtime in the yards? There actually is no difference except 5 years will be needed to refuel a nuke at half life. The shipyard rotations are essentially the same because non reactor core issues in the propulsion plant and the ships support equipment must still be repaired. We need to build 2-3 conventional steamers. Homeport two in the Pacific {one in Japan} and one on the east coast.
America-class amphibious assault ship - Aircraft carried:
AV-8B Harrier II
F-35B Lightning II
MV-22B Osprey
CH-53E Super Stallion or
CH-53K King Stallion
UH-1Y Venom
AH-1Z Viper
MH-60S Knighthawk
Wasp-class amphibious assault ship - Each ship is capable of hosting 1,894 personnel of the United States Marine Corps; almost the full strength of a Marine Expeditionary Unit (MEU).
I doubt they have managed to keep these all in port at the same time too.
I don’t know about conventional versus nuclear, but five carriers based in Norfolk gives me the heebie jeebies. We could use Savanna Puerto Rico, or even New York as alternatives.
So what's your suggestion? Move the navy base or move the interstate?
