The A-29 Super Tucano aircraft has been involved in various developments, including a purchase agreement between Embraer and Sierra Nevada Corporation. The aircraft has been delivered to the US Air Force Special Operations Command and is also being used by other countries, with Portugal receiving a dozen A-29N models. However, it is unclear if the UAE's recent deal with Embraer is for the A-29 Super Tucano or another aircraft, the C-390, as the reports seem to conflict.
