Raytheon T-1 Jayhawk

The Raytheon T-1 Jayhawk is a twin-engined jet aircraft used by the United States Air Force for advanced pilot training.

T-1A students go on to fly airlift and tanker aircraft.

The T-400 is a similar version for the Japan Air Self-Defence Force.

The T-1A Jayhawk is a medium-range, twin-engine jet trainer used in the advanced phase of Air Force Joint Specialized Undergraduate Pilot Training for students selected to fly strategic/tactical airlift or tanker aircraft.

It is used also for training Air Force Combat Systems Officers in high- and low-level flight procedures during the advanced phase of training.

It also augmented or served in lieu of the T-39 Sabreliner in the Intermediate phase of US Navy/Marine Corps Student Naval Flight Officer training until the joint Air Force-Navy/Marine Corps training pipeline split in 2010 and now remains solely in operation with the U.S. Air Force, leaving the Navy with the Sabreliner pending its eventual replacement.

The T-1 Jayhawk shares the same letter and number as the long-retired T-1 SeaStar under the 1962 United States Tri-Service aircraft designation system.

The swept-wing T-1A is a military version of the Beechjet/Hawker 400A.

It has cockpit seating for an instructor and two students and is powered by twin turbofan engines capable of an operating speed of Mach .78.

The T-1A differs from its commercial counterpart with structural enhancements that provide for a large number of landings per flight hour, increased bird strike resistance and an additional fuselage fuel tank.

A total of 180 T-1 trainers were delivered between 1992–1997.

The first T-1A was delivered to Reese Air Force Base, Texas, in January 1992, and student training began in 1993.

Another military variant is the Japan Air Self-Defence Force T-400 (400T) trainer, which shares the same type certificate as the T-1A.
