There are not ships in Texas, Rhode Island, Atlanta, or Greece.

As far as ships, it really depends on what you're interested in. CRU/DES tends to be a bit faster paced. On amphibs you'll be doing more ballasting (lowering and raising the ship in the water) and flight quarters (you'll also work the flight deck on CRU/DES).

On the Destroyers and LPDs, it will be easier to have access to replacement parts (because the ships are still in production), whereas on the older Amphibs, you have to be more creative to figure out solutions to problems.
