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.
Naval Air Station Point Mugu
In 1941, as the United States entered World War II, Point Mugu also became a training area for the Seabees. The Seabees put down a section of Marston mat runway that would become Point Mugu's first airstrip.

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 8, 2026. The linked authority identifier is Q17082712. Authority coordinates are 34.120, -119.121. 2 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
