If you really want to see the best Navy ship on the West Coast, be sure to get to the USS Midway aircraft carrier in San Diego Harbor. This carefully restored ship shows the life of a sailor on an aircraft carrier that served between World War II and Operation Desert Storm.
It's a great excursion for cruise passengers when their ships call in San Diego. And it's also a nice trip down from San Pedro via Interstate highway.
