The T-45, which had its first flight in April 1988, is fully operational at Naval Air Station (NAS) Kingsville, Texas, and is scheduled to replace the remaining T-2C Buckeyes and TA-4J Skyhawks at NAS Meridian, Mississippi, starting in November 1997. Along with the T-45 aircraft, the total training system includes two types of flight simulators: an instrument flight trainer and an operational fighter trainer.
