The T-1 Jayhawk medium-range twin-engine trainer aircraft is manufactured by Raytheon and Hawker Beechcraft. It is employed by the US Air Force as a trainer aircraft. It is derived from the commercial Beechjet 400A aircraft and is used for advanced navigator training. It can be used in both high-altitude and low-altitude training operations.
The T-39 Sabreliner was the trainer aircraft previously deployed by the US Air Force to train student pilots. Its replacement, the Jayhawk, is used to train air force navigators and naval flight officers in low-level flight procedures during the intermediate jet phase of training.
The T-1 Jayhawk was first acquired by the US Air Force, and delivered to Reese Air Force Base, Texas, in January 1992, with student training beginning in 1993. It is used to train instructor pilots in all pilot training bases including Columbus AFB, Mississipi; Laughlin AFB, Texas; Vance AFB, and Okla and Randolph AFB, Texas.
The aircraft can accommodate a maximum of two crew, namely pilot and instructor. The advanced military version of the T-1, known as T-1A, completed one million flight hours with the US Government on 15 December 2005. Approximately 180 T-1 Jayhawk aircraft were delivered between 1992 to 1997.
