Early in the 1990s, the British Army stated a requirement for an Attack Helicopter. Westland responded by negotiating a licence agreement to build the McDonnell Douglas AH-64D Apache. The Apache won the competition beating off the Bell Super Cobra, the Eurocopter Tiger and the Denal Rooivalk.

The WAH-64D differed from the US aircraft by the introduction of the Rolls-royce Turbomeca RTM-322. The first eight aircraft were built and test flown in the USA by Boeing, who had absorbed McDonnell Douglas/Vertol. The first WAH-64 flew in USA on September 25th 1998.
