San Diego is home to a very large US Navy base, as well as Naval Air Station, in San Diego Bay and Coronado Island. Thus, there were plenty of naval ships to watch and take pictures of as they sailed in and out of the bay as well as docked. Here are the ships I saw.

USS Carl Vinson CVN-70, USS John C. Stennis CVN-74, and USS Ronald Reagan CVN-76, Nimitz class nuclear-powered supercarriers:

It's interesting seeing three supercarriers in port since only two are homeported in San Diego, the Carl Vinson and the Ronald Reagan (although the Reagan is moving to Yokosuka Naval Base in Japan to replace the USS George Washington as it returns for maintenance and is being replaced with the USS Theodore Roosevelt). I've tried looking up why the three carriers were in port at the same time but I couldn't find any information. Still, it was an awesome sight.

USS Mobile Bay CG-53, Ticonderoga class guided missile cruiser:

USS Decateur DDG-73 and USS Stockdale DDG-106, Arleigh Burke class guided missile destroyers:

Also, got to see a lot of these around, Seahawks flying about (I can't tell if it's an SH-60 or MH-60 though). I saw at least 4-5 per day flying up and down the bay.
