I don't think entirely so. Perhaps to some extent there is a sampling bias, since members of the military spend a lot fo time around military facilities. But much of the reports are from aircraft carrier strike groups that tend to meander around and take trips between US bases and also patrol strategically important water areas. A significant number of the reports come from the immediate visible vicinity of San Clemente Island off the coast kind of in between San Diego and Los Angeles. San Clemente Island and San Nicolas Island next to it is the site of a US Navy base with multiple runways used to test drones and other aircraft and run training exercises from companies on the mainland. Lockheed Martin, Boeing, and Northrup Grumman all have extensive engineering facilities both in Los Angeles and San Diego. In fact in the 2004 "Nimitz incident" the carrier was undertaking a training exercise next to San Clemente when the objects were reported to have appeared on the radar display and when they sent out the fighter planes which reportedly saw an object and got it on infrared camera.
