In 2009, the Super Tucano was offered in a U.S. Air Force competition for 100 counterinsurgency aircraft.
On 12 April 2010, Brazil signed a defensive pact that opened negotiations for the acquisition of 200 Super Tucanos by the U.S. On 16 November 2011, the AT-6 was excluded from the LAS program, effectively selecting the Super Tucano.
According to GAO: "the Air Force concluded that HBDC had not adequately corrected deficiencies in its proposal… that multiple deficiencies and significant weaknesses found in HBDC’s proposal make it technically unacceptable and results in unacceptable mission capability risk".
Hawker Beechcraft's protest against its exclusion was dismissed.
However, the contract award was disputed and a stop-work was issued in January 2012.

For this procurement, the avionics are supplied by Elbit Systems of America.
Sierra Nevada, the US-based prime contractor will be building the Super Tucano in Jacksonville, Florida.
The 81st Fighter Squadron, based at Moody Air Force Base, was reactivated on 15 January 2015 and received the A-29 aircraft and provided training to pilots and maintainers from the Afghan Air Force.
 Purchased for the Afghan Air Force, all 20 aircraft are planned for turn over to the Afghans in batches by December 2018.
Until all the A-29s are turned over to the Afghan Air Force, they will not have a fixed-wing close air support aircraft, but have attack helicopter options.
