Naval Construction Battalion Center Port Hueneme is the West Coast homeport of the Navy’s Seabees (from "C.B.", the initials for "Construction Battalion"). Port Hueneme (pronounced "Why-nee-mee"), supports the training and mobilization requirements for more than 2,600 active-duty personnel.
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. 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.
