# 904th Expeditionary Air Refueling Squadron

The 904th Expeditionary Air Refueling Squadron is an inactive United States Air Force unit. It was last assigned to the 320th Bombardment Wing at Mather Air Force Base, California, where it was inactivated on 30 September 1986.
The squadron was first activated in January 1941 as the 14th Reconnaissance Squadron, which participated in anti-submarine warfare patrols after the Japanese attack on Pearl Harbor in the Gulf of Mexico before being redesignated the 404th Bombardment Squadron and moving to Alaska to participate in combat in the Aleutian Islands, where it earned a Distinguished Unit Citation. After the war, the squadron remained in Alaska until it was inactivated in 1947.
The 904th Air Refueling Squadron was activated at Mather in 1959 and provided air refueling support for its wing's Boeing B-52 Stratofortresses and other USAF aircraft until it was inactivated in 1989. In 1985 the two squadrons were consolidated into a single unit.
In 2002, the consolidated squadron was converted to provisional status as the 904th Expeditionary Air Refueling Squadron and assigned to Air Mobility Command. There have been no known deployments of the squadron as an expeditionary unit.

## History
### World War II

The squadron was first activated in January 1941 as the 14th Reconnaissance Squadron (Heavy) in the Southeast Air District at Miami Municipal Airport and attached to the 44th Bombardment Group. Since a reorganization of General Headquarters Air Force in September 1936, each bombardment group of the Army Air Forces (AAF) had an assigned or attached reconnaissance squadron, which operated the same aircraft as that group's assigned bombardment squadrons. That arrangement continued for units like the 14th that were designated as heavy bombardment units. The squadron was equipped with Consolidated B-24 Liberators. In June the squadron moved to MacDill Field, Florida, where the 44th Group and its three assigned squadrons were located. Following the Japanese attack on Pearl Harbor, the squadron began to participate in antisubmarine patrols.
In May 1942, the squadron was redesignated the 404th Bombardment Squadron and assigned to the 44th Group. As the rest of the 44th Group, which had been acting as an Operational Training Unit began intensive training for deployment to the European Theater of Operations, the squadron was detached from the 44th and sent to reinforce the 28th Composite Group in Alaska in July 1942.
The squadron's 1942 move to Alaska in July 1942 was in response to the Japanese invasion of the Aleutian Islands. It flew long-range bombardment missions of enemy targets in the Aleutians during 1942 and 1943. The following year it attacked the Kuril Islands, for which it was awarded the Distinguished Unit Citation. The squadron remained in Alaska after Japanese forces were driven from the Aleutians. In late 1944, Eleventh Air Force modified two B-24D aircraft for ferret missions. These aircraft were assigned to the 404th, although mission tasking was performed directly by the Eleventh Air Force Signal Office. Ferret missions began in January 1945, and one of these aircraft was lost on a mission on 1 May 1945. The squadron continued to fly long-range reconnaissance operations from Shemya Army Air Base until it was inactivated in 1947.

### Cold War

The 904th Air Refueling Squadron, Heavy was activated on 1 March 1959 by Strategic Air Command (SAC) at Mather Air Force Base, California, as the air refueling component of the 4134th Strategic Wing. Operating Boeing KC-135 Stratotankers, it provided air refueling support to the B-52 Stratofortress strategic bombers of its parent wing and other USAF units as directed. The squadron transferred to the 320th Bombardment Wing in 1963 when SAC replaced its Major Command controlled (MAJCON) strategic wings with Air Force controlled (AFCON) bombardment wings that inherited the honors earned by World War II bombardment groups.
The 904th deployed to the western Pacific region to support combat operations of deployed SAC units and tactical aircraft over Southeast Asia during the Vietnam War between 1966 and 1969. The squadron earned two Air Force Outstanding Unit Awards during the 1960s. In 1985, the 904th and the 404th Bombardment Squadron were consolidated when the United States Air Force combined inactive units that had served in World War II with squadrons that had been established after the war ended. The squadron was inactivated with its parent wing in 1989 when the B-52G was retired. Its equipment and personnel were reassigned to other units.
In 2002, the squadron was converted to provisional status and assigned to Air Mobility Command as the 904th Expeditionary Air Refueling Squadron.
