Background
The world’s first and most-produced supersonic trainer, the Northrop T-38A Talon has trained over 5,000 military pilots since its introduction to service in 1961. Of the nearly 1,200 T-38A’s produced, the US Air Force continues to operate over 500 of the type as of 2014, of which most will be upgraded to T-38C configuration with new wings and improved avionics, including heads-up display and inertial navigation systems, and will continue to operate them until at least 2020.
