In August 2009, the A160T was chosen by the US Marine Corps along with the Kaman K-MAX to demonstrate the ability to move 6,000 lb (2,722 kg) of cargo in less than 6 hours for three consecutive days. The A160T successfully completed the re-supply demonstration in early March 2010. In December 2010, NAVAIR awarded a $29.9 million contract to Boeing for two A160Ts and control systems. Kaman received a similar contract worth $46M. NAVAIR issued a stop-work order on the A160 in December 2011, before a Quick Reaction Assessment. The K-MAX was eventually chosen over the A160T for the unmanned resupply role by the Marines, and was sent to Afghanistan in 2011.
