The U.S. Air Force’s program to acquire a light attack aircraft appears to be on hold indefinitely. One issue that contributed to the decision to cancel its planned procurement and to re-open the OA-X experiment with alternative platforms was uncertainty regarding the international demand for a light attack platform. However, the international market appears to have made its choice. The A-29 Super Tucano, built by a team headed by Sierra Nevada Corporation and Embraer, is leading all possible contenders.
