AN/SPN-35 Aircraft Control Approach Central

The AN/SPN-35, installed on the Tarawa-class amphibious assault ships, is a computerized automatic landing system radar that provides precise control of aircraft during their final approach and landing. The equipment can automatically acquire, control, and land a suitably equipped aircraft on aircraft carriers under severe ship motion or weather conditions.

The AN/SPN-35B is a short-range, three-dimensional, carrier-controlled-approach radar system used for precision landing approaches during adverse weather conditions. The AN/SPN-35B may also be used for height-finding and radar surveillance of aircraft. The AN/SPN-35B displays both azimuth and elevation data on a radar control-indicator enabling the radar operator to direct the aircraft pilot along a predetermined glide path and azimuth course line to a carrier-controlled-approach optical landing system transition point one mile from ownship.
