The T-45A aircraft, the Navy version of the British Aerospace Hawk aircraft, is used for intermediate and advanced portions of
the Navy/Marine Corps pilot training program for jet carrier aviation and tactical strike missions. The T-45A will replace the T-2 Buckeye
trainer and the TA-4 trainer with an integrated training system that includes the T-45A Goshawk aircraft, operations and instrument fighter
simulators, academics, and training integration system. There are two versions of T-45 aircraft currently in operational use at this time,
the T-45A and T-45C derivatives. The T-45A, which became operational in 1991, contains an analog design cockpit while the new T-45C
(began delivery in December 1997) is built around a new digital \"glass cockpit\" design.
