Naval Base Ventura County (NBVC) is a United States Navy base in Ventura County, California. Formed by the merger of NAS Point Mugu and CBC Port Hueneme, NBVC is a diverse installation composed of three main locations — Point Mugu, Port Hueneme, and San Nicolas Island. The base serves as an all-in-one mobilization site, deep water port, railhead, and airfield. NBVC supports more than 100 tenant commands with a base population of more than 19,000 personnel, making it the largest employer in Ventura County. History Naval Construction Battalion Center Port Hueneme The facility at Port Hueneme was built as a temporary depot in the early days of World War II to train, stage, and supply the newly created Seabees (from "C.B.", the initials for "Construction Battalion"). The base was officially established and began operating May 18, 1942 as the Advance Base Depot. In 1945 the Advance Base Depot was renamed the Naval Construction Battalion Center. During the Korean War, almost all Navy construction equipment and supplies for the war were routed through CBC Port Hueneme.

This facility was the site where most of the Navy's missiles were developed and tested during the 1950s and 1960s, including the AIM-7 Sparrow family and the AIM-54 Phoenix air-to-air, Bullpup air-to-surface, and Regulus surface-to-surface missiles.NAS Point Mugu has dominated the area since the 1940s, and is one of the few places in the area that is not agricultural. The base has been home to many ordnance testing programs, and the test range extends offshore to the Navy-owned San Nicolas Island in the Channel Islands. In 1963 the U.S. Navy Marine Mammal Program was established on a sand spit between Mugu Lagoon and the ocean. The facility was relocated in 1967 to Point Loma in San Diego, California. NAS Point Mugu was the airfield used by former President Ronald Reagan during his presidency on visits to his Santa Barbara ranch. The airfield was used during the state funeral in 2004, as the place where the
