Originally, in the Type 22 and Sea Wolf equipped Leander class, this was the radar Type 967 / 968 combination; the D-band Type 967 providing long range surveillance and the E-band Type 968 providing short range target indication. Latterly, these functions have been taken over by the radar Type 996 3D surveillance radar.
Originally the Type 910, with a dual-role I/J band radar, was used but this suffered from poor performance locking onto low-altitude targets hidden in the background sea clutter in the Malvinas War. Subsequently, the lighter Type 911 supplanted the Type 910, with a separate I-band radar to gather targets and K band radar to provide the lock. This system is based on the Blindfire tracker of the Rapier missile and was fitted in the 7th Type 22 Frigate onwards. Unlike Type 910, Type 911 is not reliant on the CCTV function, although this is retained as a back up and to provide a record of engagements.
