Also known as AIA-1, the AN/APS-6 airborne radar was a simplification of AN/APS-4 (ASH) suitable for single-seat fighters. It used a much smaller display, just 2 inches (5 cm) in diameter, which eliminated the need for a radar operator and served as a radar gunsight.

The prototype was developed in September 1943, but difficulties with the RF head head delayed production by Westinghouse until April 1944. Almost all the sets produced during the war ended up using the ASD head.
