The US Air Force is choosing Boeing’s MH-139 Helicopter as replacement for its ageing fleet of UH-1N Hueys. The company is being awarded with an initial firm-fixed-price contract that provides for the delivery of four aircraft at a cost of $375.5 million. This is the first award of a $2.38 billion contract that precedes the acquisition of a total of 84 MH-139s. The MH-139 is derived from the Leonardo AW139 and will be used to protect America’s intercontinental ballistic missile bases. The new variant is said to offer more than $1bn in savings in acquisition costs and lifecycle expenses over 30 years when compared with competitor aircraft. Work is expected to be completed by September 2031.
