Pratt & Whitney TF30

The TF30 was Pratt & Whitney's first afterburning turbofan. Selected for the F-111, there were problems matching the engine with the aircraft, specifically the inlet system. The P-412 version for the F-14 required redesign and various fixes eventually leading the aircraft to be re-engined with General Electric F110 engines.
First flown in 1964, the TF30 was in production through 1986.
