The SU was a surface search radar developed from the SK-2 air search radar.  It was designed for destroyer escorts and was equipped with three remote PPI displays and IFF. Since small ships could not carry many specialized technicians, the radar was designed to be as simple and reliable as possible and its components were designed to be easily manhandled through shipboard compartment doors. The antenna was stablized to compensate for the rolling of smaller ships in heavy seas.
