It was based at Langley Field, Virginia throughout its existence, and equipped with Boeing B-17 Flying Fortress, Douglas B-18 Bolo, and Consolidated B-24 Liberator aircraft.

[3] The group also conducted training on equipment and antisubmarine tactics for Army Air Forces units and personnel.

After the Navy assumed responsibility for land based aerial antisubmarine operations in 1943, the unit continued to conduct radar training for bomber crews until it was disbanded.

[2][5] The group provides analysis of intelligence from multiple sources to support airpower employment, focusing on threat tactics, characteristics, and capabilities.

Col Dolan's suggestion was accepted, and following testing of the ASV radars with the Navy near New London, Connecticut, the crews moved to Langley, where they were initially attached to the 20th Squadron.

Equipped with auxiliary fuel tanks, radar and a powerful searchlight, the B-24 was ideal for extended antisubmarine patrols.

[10] World War II era radar sets, particularly the newly operational ones the group tested in its bombers, were difficult to maintain, and scientists assigned to the group for testing found that instead, much of their time was consumed by maintenance of the unit's radar equipment.

[11] As a result, the Army Air Forces expanded the 1st to establish a school within the group to train ground personnel in maintenance of radar equipment.

[6] However, the Army Air Forces found that standard military units, based on relatively inflexible tables of organization, were proving less well adapted to training and other support missions.

The group's location at Langley also gave it access to the research and test facilities of the National Advisory Committee on Aeronautics.

Combined with the use of sonobuoys to listen for the sounds of a submarine, MAD provided a high probability of conducting a successful attack.

LORAN permitted efficient control of converging air and surface forces for a coordinated attack.

[3] Another task of the 1st Sea Search Attack Group was to develop techniques for using ASV radar to find surfaced submarines.

[21] On 9 July 1943, the Army Air Forces agreed to the transfer of its antisubmarine mission to the Navy's Tenth Fleet.
