The AN/SPS-10B was a medium range, C-band, surface warning radar with a limited air capability. In the Canadian Forces, this type was used in pre-DELEX steamers and training facilities. The AN/SPS-10B was used for the detection, ranging and tracking of surface contacts and to a limited extent, air contacts as well. Range and bearing information was passed to a PPI type display. This radar type had the potential to be used with IFF/SIF equipment so the SPS-10 was originally fitted with a built in beacon. The RCN never used this feature, so it was disabled.
