Rooted in coastal-defense fortifications dating to 1852, Naval Base Point Loma sits at the southern tip of the Point Loma, San Diego peninsula and encompasses seven facilities supporting approximately 22,000 Navy and civilian personnel. The installation's southern boundary adjoins Fort Rosecrans National Cemetery, where burials marking every American conflict since the Indian Wars rest on the same ridgeline that shelters active submarine berths below. NBPL serves as the Pacific homeport for Los Angeles-class and Virginia-class fast-attack submarines and hosts Naval Information Warfare Systems Command, the service's hub for fleet cyber and C4ISR development. The headland's dual identity as military asset and national landmark is anchored by Cabrillo National Monument, whose preservation mission is led by the Cabrillo National Monument Foundation on land the Navy still uses for strategic communications infrastructure. The base's most complex current initiative is integrating AUKUS trilateral submarine-sustainment protocols into its waterfront facilities, a program formalized by the 2023 agreement signed on-site.
