Pratt & Whitney TF30 is the first production afterburning turbofan, developed for the General Dynamics F-111 and later adapted for the Grumman F-14 Tomcat. Early F-111 variants used nominal ratings around 11,350–13,400 pounds with later models reaching up to 25,100 pounds in afterburner; the family established a major military turbofan boundary and remains a source-backed legacy propulsion identity.
