The
AgustaWestland AW101 is a medium-lift
helicopter used in both military and civil applications. It was developed by a joint venture between
Westland Helicopters in the UK and
Agusta in Italy in response to national requirements for a modern naval utility helicopter. Several operators, including the armed forces of Britain, Denmark 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.
