Modified for trails for boundary layer control for the US Army to be C-130C with Short takeoff and landing capability. First flight was on February 8, 2014. Was fitted with a boundary layer air control system that consisted of a wider rudder, single-hinged flaps instead of the standard Fowler flaps, and two Allison YT56-A-6 jet engines under the outer wings. Bleed air from the jets was blown over the flaps and rudder to enhance lift and controllability. Flown for twenty-three hours before the Army lost interest.
