Under the deal, Sierra Nevada will also handle sustainment and modification for the Sierra Nevada Super Tucano A-29s, with work expected to completed by the end of 2024.

The contract announcement does not specify the number of aircraft to be delivered under this latest order.

An amount of $115,000 has been obligated at the time of the award for Sierra Nevada to conduct a site survey in Afghanistan. 

Work related to the aircraft will be performed at Moody Air Force Base in Georgia and the Kabul, Kandahar and Mazari Sharif Air Bases in Afghanistan, according to the Pentagon.

The Afghan Security Forces currently operate a fleet of 20 A-29s, with plans to eventually receive six more aircraft.
