Agusta Westland EH101

The AgustaWestland AW101 is a medium-lift helicopter used in both military and civil applications. First flown in 1987, it was developed by a joint venture between Westland Helicopters in the United Kingdom and Agusta in Italy in response to national requirements for a modern naval utility helicopter. Several operators, including the armed forces of Britain, Denmark, Norway and Portugal, use the name Merlin for their AW101 aircraft. It is manufactured at factories in Yeovil, England and Vergiate, Italy; licensed assembly work has also taken place in Japan and the United States.

Prior to 2007, the aircraft had been marketed under the designation EH101. The original designation was in fact EHI 01, from the name given to the Anglo-Italian joint venture – European Helicopter Industries – but a transcription error changed this to EH101 and the designation stuck. In 2000, Westland Helicopters and Agusta merged to form AgustaWestland, leading to the type's current designation.
