The
Pratt & Whitney TF30 (company designation
JTF10A) was a military low-bypass
turbofan engine originally designed by
Pratt & Whitney for the subsonic
F6D Missileer fleet defense fighter, but this project was cancelled. It was later adapted with an
afterburner for supersonic designs, and in this form it was the world's first production afterburning turbofan, going on to power the
F-111 and the
F-14A Tomcat, as well seeing use in early versions of the
A-7 Corsair II without an afterburner. First flight of the TF30 was in 1964 and production continued until 1986.
