San Diego Bay is a natural harbor and deepwater port located in San Diego County, California, near the U.S.–Mexico border. The bay, which is 12 miles (19 km) long and 1 to 3 miles (1.6 to 4.8 km) wide, is the third largest of the three large, protected natural bays on California's 840 miles (1,350 km) of coastline, after San Francisco Bay and Humboldt Bay. The highly urbanized land adjacent to the bay includes the city of San Diego and four other cities: National City, Chula Vista, Imperial Beach and Coronado. The bay is considered to be one of the premier natural harbors on the West Coast.[4]
San Diego Bay was colonized by Spain beginning in 1769. It served as base headquarters of major ships of the United States Navy in the Pacific until just before the United States entered World War II, when the newly organized United States Pacific Fleet primary base was transferred to Pearl Harbor. The bay remains as a home port of major assets, including several aircraft carriers of the United States Pacific Fleet. As a result of base closures beginning in the 1980s, facilities in San Diego Bay are the only remaining major naval base facilities still in operation in California.
