The Westland Lynx was designed and built by Westland Helicopters at its factory in Yeovil. Both battlefield and naval variants were developed, which went into operational usage in 1977 and were later adopted by the armed forces of over a dozen nations, where it primarily serves in the battlefield utility, search and rescue and anti-submarine warfare roles.
The initial design (then known as the Westland WG.13) was started in the mid-1960s, with the Lynx making its first flight on 21st March 1971. In 1972, a Lynx broke the world record over 15 and 25km by flying at 321.74 km/h. It also set a new 100km closed circuit record shortly afterwards flying at 318.504 km/h.
In 1986, a Lynx specially modified with BERP (British Experimental Rotor Programme) rotor blades, registered G-LYNX and piloted by Trevor Egginton set an absolute speed record for helicopters over a 15 and 25km course by reaching 400.87 km/h.
The British Army ordered 100 Lynx AH (Army Helicopter) Mk.1 for various roles, including tactical transport, armed escort, anti-tank warfare (with eight TOW missiles) reconnaissance and evacuation.
