Hampton Roads
Beginning in 1917, as the United States became involved in World War I under President Woodrow Wilson, formerly rural Sewell's Point became the site of what grew to become the largest Naval Base in the world which was established by the United States Navy and is now known as the Naval Station Norfolk.
Naval Air Station Alameda
Air support training unit No. 2 at Alameda included the fleet radar operator's school, Link celestial navigation Trainer school, and aviation storekeeper school. As World War II continued, Alameda became headquarters for a system of auxiliary airfields:Alameda remained an important naval base through the Cold War. From 1949 to 1953, the Navy based the Lockheed R6V Constitution—the largest airplane ever listed on the Navy inventory—at NAS Alameda. The two prototypes regularly flew between nearby NAS Moffett Field and Pearl Harbor, Hawaii. The base was the focus for northern California United States Navy Reserve drill after 1961. Runways were lengthened for jet aircraft, and the airport was renamed Nimitz Field in 1967 following the death of Admiral Chester W. Nimitz. Nuclear powered aircraft carriers were home ported at Alameda into the 1990s, and thousands of local civilians were employed overhauling aircraft at the naval aviation depot.
