Raytheon T-6A Texan airplane model. The Raytheon Aircraft Company [formerly Beechcraft] T-6A Joint Primary Air Training System (JPATS) turboprop is designed as a dedicated training aircraft possessing jet-like handling characteristics. Replacing the Air Force's T-37 and the Navy's T-34C aircraft, which are 37 and 22 years old, respectively, the T-6A will offer better performance and significant improvements in training effectiveness, safety, cockpit accommodations and operational capabilities. Seven hundred and forty T-6A aircraft will be purchased by the United States Air Force and the United States Navy. The Air Force and Navy transition to the T-6A is expected to take approximately 10 years. The Air Force will steadily replace T-37s with T-6s at all Air Education and Training Command joint specialized undergraduate pilot training bases.
