A general purpose transport variant of the Wessex Mk1, modified to accept two Rolls-Royce Gnome turboshafts. The twin engined Wessex, powered by twin coupled 1350shp Bristol Siddeley (later Rolls Royce) Gnome turbines, proved to be one of Westland's most successful and enduring aircraft. The type served with the RAF (HC Mk2) and the Royal Navy (HU Mk5), a number were still in service in 1998, including the two HCC Mk4s with The Queen's Flight. A version was also produced for the civil market.
