Boeing has been awarded a $189.2m firm-fixed-price contract by the US Army Contracting Command to provide 16 AH-64D Apache aircraft and related support.

The AH-64 Apache Longbow is a twin-engine, four-blade attack helicopter equipped with a tail wheel-type landing gear arrangement and a tandem cockpit to accommodate a crew of two.

The helicopter features open systems architecture and 26 advanced technology improvements, including level four unmanned aerial vehicle control for increased situational awareness.

Work will be carried out at the company’s facility in Arizona, US, and is estimated to be completed by 28 February 2014.
