Boeing submitted its bid for the U.S. Air Force to buy up to 84 MH-139 helicopters to replace its Huey fleet.  The Boeing proposal for its MH-139 helicopter could save more than $1 billion in acquisition costs and lifecycle expenses.

MH-139 is a militarized version of the Leonardo Helicopters commercial AW139. Outside, it has a rear intake engine that can ward off heat seeking missiles, flare dispensers and large windows.  Inside, there's increased carrying capacity, a glass cockpit with advanced avionics, and a four-axis digital autopilot with auto-hover.

The MH-139 offering is for the Air Force’s UH-1N Replacement program.  Hueys currently protect intercontinental ballistic missile sites and transport U.S. government and security forces.
