The AgustaWestland AW139 is a 15-seat medium-sized twin-engined helicopter developed and built by AgustaWestland (now part of Leonardo). It is marketed at several different roles, including VIP/corporate transport, offshore transport, fire fighting, law enforcement, search and rescue, emergency medical service, disaster relief, and maritime patrol.[3] In addition to AgustaWestland's manufacturing facilities in Italy and the United States, the AW139 is produced in Russia by HeliVert, a joint venture between AgustaWestland and Russian Helicopters.
The AW139 was originally designed and developed jointly by Agusta and Bell Helicopters and marketed as the Agusta-Bell AB139, being redesignated AW139 when Bell withdrew from the project. Since entering service in 2003, the AW139 has become one of AgustaWestland's most influential products; it has been subsequently developed into the enlarged medium-lift military-orientated AW149
