SG (later renamed to SG-1) was operating in S-Band surface search radar designed for installation on destroyers and larger ships. The radar antenna is located on the mainmast of the ship. SG had A-scopes and PPI displays. It would pick up submarine periscopes up to 10,000 yards.
Nearly 1 000 Model SG radars were produced during the war (1942 … 1943). Many remained in service over a period of nearly two decades.
