AN/APS-3 was operating in X-Band air-to-surface search and bombing radar. It could also be used for navigation and for homing a radar beacon.
The antenna unit consisted of a parabolic reflector and an antenna feed through a waveguide. It was connected to a motor via a gearbox. This allowed the antenna to be slewed in a 160° sector at about 35 cycles per minute. The display was on a rectangular illuminated B-scope. Land masses were displayed as bright areas. Coastlines and rivers were shown as dark contrasts.
The radar was built between 1943 and 1946.
