 The characteristics of the wing, being relatively short and straight, enabled the lengthy aerial for the primary reconnaissance sensor, the Red Drover X-band radar, to be contained within the fuselage, as the wing provided little obstruction and therefore interference with the radar.A total of four Armstrong-Siddeley P.156 engines, two each being mounted in an over-under arrangement in pods positioned at the extreme tips of the wings, provided propulsion.The engine nacelles included variable-geometry air intakes, while the engines themselves were equipped with convergent-divergent nozzles.
