SC was an American-made air and surface-search radar used during World War II by the United States Navy.

All sets have an "A" scope, provision for Identification friend or foe (IFF) connections, and work with a gyro-compass repeater.

[2] With antennas at 100', SC and SC-1 (without preamplifier) have a reliable maximum range of 30 miles on medium bombers at 1,000' altitude.

There is no elevation control on any of the sets, but height can be estimated roughly from positions of minimum signal strength.

SC and SC-1 require primary power of 1500 watts at 115 volts, 60 cycles.
