The Raytheon T-1 Jayhawk, a twin-engine jet, is utilised by the U.S. Air Force for advanced pilot training. Students trained on the T-1A proceed to operate airlift and tanker aircraft.
The T-400, a variant of the T-1A, serves the Japan Air Self-Defence Force.
The T-1A Jayhawk, designed for medium-range training, is employed in the advanced phase of Joint Specialised Undergraduate Pilot Training, preparing students for strategic/tactical airlift or tanker roles.
It also trains Air Force Combat Systems Officers in both high- and low-level flight procedures.
Previously, it supplemented the T-39 Sabreliner for intermediate-phase training of US Navy/Marine Corps student Naval Flight Officers until 2010, when the joint training program was divided, leaving the T-1 solely with the U.S. Air Force.
The T-1 Jayhawk shares its designation with the retired T-1 SeaStar under the 1962 United States Tri-Service aircraft designation system.
The T-1A, a military adaptation of the Beechjet/Hawker 400A, features a swept-wing design, seats for an instructor and two students, and is powered by engines capable of Mach .78.
It differs from its commercial version with structural enhancements for frequent landings, increased bird strike resistance, and an extra fuel tank.
From 1992 to 1997, 180 T-1 trainers were delivered, with the first arriving at Reese Air Force Base in January 1992, and student training commencing in 1993.
The Japan Air Self-Defence Force’s T-400 trainer also holds the same type certificate as the T-1A.
