The T-6A was introduced to Moody Air Force Base and Randolph Air Force Base in 2000-2001, and the Air Force awarded the full rate T-6 production contract in December 2001. Laughlin Air Force Base began flying the T-6 in 2003 where it is now the primary basic trainer, replacing the T-37. Vance Air Force Base completed transitioning from the T-37 to the T-6 in 2006. That year, Columbus Air Force Base began its transition, and retired its last T-37 in April 2008. The last active USAF T-37Bs were retired at Sheppard Air Force Base in the Summer of 2009.
The Beechcraft T-6 Texan II is a single-engined turboprop aircraft built by the Raytheon Aircraft Company (now Hawker Beechcraft).
The T-6 is used by the United States Air Force for basic pilot training and by the United States Navy for Primary and Intermediate Joint Naval Flight Officer (NFO) and Air Force Combat Systems Officer (CSO) training. It has replaced the Air Force's T-37B Tweet and is replacing the Navy's T-34C Turbo Mentor. The T-6A is also used as a basic trainer by the Canadian Forces (CT-156 Harvard II), the Luftwaffe of Germany, the Greek Air Force, the Israeli Air Force (Efroni), and the Iraqi Air Force.
