ASD began with a proposal to develop a 3-cm surface search radar for the TBF Avenger. Development was slow due to the difficulty of installing a long waveguide to the antenna nacelle, and the set ended up being used on the PV-1 Ventura. It proved somewhat unreliable.

Both pilot and bombardier were supplied with a B scope.
