Meet the U.S. Air Force's new advanced trainer: The Boeing-SAAB T-7A Red Hawk. The first prototype flew in 2016 and the aircraft was selected by the Air Force in 2018 to replace the aging T-38. The initial goal is procurement of 351 T-7As. Boeing-SAAB hope for plenty more sales, of course.
The T-7A is powered by a single afterburning F404 turbofan, the same engine powering the F/A-18A-D.

Apparently the latest Pentagon budget has delayed the program a year due to budgetary limitations.
