One of three prototypes that were built, before the T-46 project was canceled. It was destined to replace the T-37 trainer, but upgrading the existing T-37 fleet was in favour.
The mighty "Thunder Piglet"! The T-46A was designed as a New Generation Trainer in the early 80's to replace the Cessna T-37 in USAF service. Sadly, the T-46 was overweight and had greater drag than predicted and the whole project was cancelled in 1987.
