Red Steer, also known as ARI 5919 and ARI 5952 depending on the version, was a tail warning radar used on the British V bomber force. Built by EKCO, it was developed from the experimental AI.20 radar for the English Electric Lightning. The Lightning required its radar to be remotely installed in the nose of the aircraft, and this made the set equally suitable for remote mounting in the tail of the bombers.
