The Air Force already retired the T-37B Tweet and is flying the T-6A Texan II as its primary introductory flight trainer.  The T-6 was the result of a “joint” program between the Air Force and Navy.  The Navy has been transitioning from its T-34C Turbomentor to the Navy version of the trainer, the T-6B.

An article at the Navy Times notes the T-6 is a huge leap from the earlier T-34 — even sporting ejection seats.  Distressed pilots in the T-34 had to manually jump over the side if they needed to exit the aircraft in flight, a la WWII.
