Preserved outside, Lynx 2 XW839 is the 5th protoype of the WG-13 / Lynx and the oldest original complete Lynx in existence. It first flew on 19 June 1974 and was used as a weapons test platform to prove the proposed Hawk-swing anti-tank missile system. 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.

Helicopters were parked too close together for photos. Excellent museum with many helicopters from many countries. Called by recently but opening hours were too late in the morning, so decided to head off elsewhere. XW839 is HMS Thunderer.
