Operations and missions

Coast Guard Air Station San Francisco (CGAS) located at the San Francisco International Airport is one of five air stations in the Eleventh Coast Guard District. Currently, Air Station San Francisco operates four MH65 Dolphin helicopters that provides its primary mission search and rescue. CGAS San Francisco also supports a wide range of other Coast Guard operations such as Maritime Law enforcement, port security, Aids to Navigation support and Marine Environmental Protection to approximately 300 miles (480 km) of coastline from Point Conception to Fort Bragg 24 hours a day, 7 days a week, 365 days a year.

History

Coast Guard Air Station San Francisco was completed on February 15, 1941, making it one of the longest tenured tenants at SFO. The air station operated a PBY-5 Catalina and two RD-4 Dolphins. On November 1, 1941, the aircraft and personnel were placed under Navy command where they continued to conduct Search and Rescue and Coastal Patrols through the end of World War II. Coast Guard Air Station San Francisco was also tasked with aiding in the construction of the highly classified and secret Long Range Navigation (LORAN) stations in the North Pacific in 1943. Proving an invaluable asset in this important mission, the San Francisco-based PBY-5 Catalina was instrumental in the completion of the Aleutian LORAN chain by transporting personnel, supplies and building materials. World War II the base was called Naval Auxiliary Air Facility Mills Field and Coast Guard Air Station, San Francisco.^[2]

After World War II, the Air Station resumed normal operations under Coast Guard control after release from the Navy on June 30, 1946. The first helicopter stationed here in San Francisco was the HO3S-1 Dragonfly in 1947. In the early fifties the Grumman HU-16 Albatross replaced the air stations aging World War II fixed wing inventory. This general purpose amphibian, affectionately known as the "Goat", proved to be a highly adaptable platform for SAR and LE. Eventually, the Air Station received the HH-52A Sea Guard helicopter in 1963 which was a significant improvement over its predecessor with its improved flight characteristics and capabilities.

Also stationed at San Francisco were the C-130s which when they were moved to the newly constructed Coast Guard Air Station Sacramento in 1978, ended 37 years of Coast Guard fixed wing aviation in San Francisco. In 1991, Air Station San Francisco received its first HH-60 J-Hawk to replace the HH-3F Pelican as the medium range Search and Rescue Helicopter. Restructuring in Coast Guard Aviation lead to a short stay of the HH-60 in San Francisco and in June 1996, four HH-65s were moved to San Francisco from San Diego. In the fall of 2001, the Air Station transitioned to the HH-65B, an upgrade in the avionics package. In the spring of 2006, the HH-65B was upgraded to the HH-65C after the installation of Turbomeca Arriel 2C2-CG engines.

While the airframes have evolved, the primary mission of Air Station San Francisco has remained unchanged for six decades, maritime Search and Rescue along 300 miles (480 km) of coastline from Point Conception to Fort Bragg. In addition to SAR, Air Station San Francisco has expanded its missions to include Homeland Security, Maritime Law Enforcement, Environmental Protection, Aids to Navigation, Logistics, and Cliff Rescue.^[3]

Point Mugu

After CGAS Los Angeles's lease on facilities at the Los Angeles International Airport expired, the air station closed in September 2016. Administratively, its component units were relocated to Naval Air Station Point Mugu in Point Mugu, California and merged with/became a satellite of CGAS San Francisco. NAS Pt Mugu has been part of Naval Base Ventura County since 2000.
