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-Defense Force]].

==Design and development==

The T-1A Jayhawk is a medium-range, twin-engine jet trainer used in the advanced phase of Air Force [[Undergraduate Pilot Training|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 Officer]]s 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]]/[[United States Marine Corps|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 [[T2V SeaStar|T-1 SeaStar]] under the [[1962 United States Tri-Service aircraft designation system]].

The swept-wing T-1A is a military version of the [[Hawker 400|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 and 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-Defense Force]] T-400 (400T) trainer, which shares the same [[type certificate]] as the T-1A.<ref>{{Cite web|url=http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgMakeModel.nsf/0/3ba326e92f6abe008625732900523228/$FILE/A16SW%20rec%2025.pdf,|title=TC Data Sheet A16SW}}</ref>
