In September 2017, Boeing formally submitted the MH-139 in bid to replace US Air Force's UH-1N fleet.

The Boeing MH-139 helicopter is based on the Leonardo Helicopters AW139. Nearly 900 AW139s are in service with more than 250 government, military and commercial operators around the world.

Boeing military rotorcraft expertise, combined with the non-developmental, multi-mission helicopter, will provide exceptional value and capability to the Air Force and taxpayers.
