The 20 aircraft are being supplied for the U.S. Air Force's Light Air Support program and will be transferred to the Air Force of Afghanistan.
The Brazilian aircraft will be assembled at a new Embraer facility in Jacksonville, Fla., and the company said deliveries will begin in the middle of next year.
"This facility will perform pre-equipping, mechanical assembly, structural assembly, systems installation and testing, and flight testing of A-29 Super Tucano aircraft," said Daniel W. Culleton Jr., Embraer general manager, who will oversee production in Jacksonville. "It is the latest in a series of recent expansions by Embraer in Florida and the first for Defense & Security."
Embraer won the Air Force contract in late February with the Sierra Nevada Corp., the prime contractor for the project.
Embraer said more than 100 U.S. companies will supply parts and services for the A-29 Super Tucano.
