Twenty attack aircraft that can also be used for training and to provide the Army with close air support were desired. The two contenders were the Embraer A-29 Super Tucano and the Beechcraft AT-6. Embraer won the previous contract but the tendering process was cancelled after it was discovered that proper procedures were not followed. A winner for the new contract was expected in June 2013 with first deliveries expected to begin in the third quarter of 2014, about 15 months after originally planned. The Super Tucano was declared the winner of the contract again in 2013. The contract was to be completed by Sierra Nevada Corp. for 20 A-29 Super Tucanos with an expected delivery date of between December 2015 and 2018. DOD purchased the Super Tucanos for $427 million.
