I don't even like the idea of having 5 in Norfolk and 1 here, I'd much rather see one each in Portsmouth, Newport or Groton, Norfolk, Kings Bay, Mayport, and Key West or Corpus Christi.
Hell, I don't even want Mayport to have more then 2, EVER! Besides Kings Bay is really the Florida / Georgia coasts deepest natural harbor and river entrance. Which would be why the Government decided to build Fort Clinch there rather then Mayport back in the 1840-50's. It would also be why our first railroad of any consequence ran from Fernandina to West Florida.
