First Flight: 19 June 1974.
Purpose: Fifth prototype, The first to have the slender, longer AH 1 nose and tail boom/pylon. Used as a weapons test platform to prove the proposed HAWKSWING missile system.
Fate: By 1980, it had been retired from the test programme and moved to HMS Thunderer, RNEC. It spent a brief time at Filton with Rolls Royce in 1985 until being moved to the fire dump at RNAS Yeovilton in 1995. In 1996, it was moved to the Helicopter Museum, W-S-M, where it still resides in a fairly complete condition but stripped to almost bare metal. This is the oldest original, complete Lynx in existence.
