1942: The start of the Second World War sent naval survey teams up and down the Pacific coast looking for new locations for naval facilities. One team was looking for a site to build a naval base to support naval construction activities at advanced bases in the Pacific. The team came to Port Hueneme, California and recognized it as an ideal port, because it was the only Pacific deep water port between Los Angeles and San Francisco. Word of the discovery was sent to Admiral Ben Moreell, Chief of the Bureau of Yards and Docks, who was busily putting together the new construction battalions. Port Hueneme therefore was tentatively selected as the site for the advanced base depot on the Pacific coast. On February 16, 1942, Admiral Moreell sent his recommendations to the Chief of Naval Operations and it was speedily approved.
