Marine Corps Supply Forwarding Annex, Islais Creek

The Marine Corps Supply Forwarding Annex at Islais Creek, located in San Francisco, was established during World War II to serve as a critical logistics and supply hub for the United States Marine Corps in the Pacific theater. Operational from the early 1940s, the annex facilitated the storage, management, and rapid distribution of military equipment, supplies, and materiel destined for Marine units deployed overseas. Its strategic location near major ports and transportation lines enabled efficient support for large-scale amphibious operations across the Pacific islands. After the war, as military logistics operations scaled down, the annex’s activities gradually diminished, and the facility was eventually decommissioned.
