Pratt & Whitney F100
afterburning turbofan engine that powers the F-15 Eagle and F-16 Fighting Falcon.
The Pratt & Whitney F100 (company designation JTF22) is a low bypass afterburning turbofan engine. It was designed and manufactured by Pratt & Whitney to power the U.S. Air Force's "FX" initiative in 1965, which became the F-15 Eagle. The engine was to be developed in tandem with the F401 which shares a similar core but with an upscaled fan for the U.S. Navy's F-14 Tomcat. The F401 was later abandoned due to costs and reliability issues. The F100 also powered the F-16 Fighting Falcon for the Air Force's Lightweight Fighter (LWF) program.
Development
In 1967, the United States Navy and United States Air Force issued a joint engine Request for Proposals (RFP) for the F-14 Tomcat and the FX, which became the parallel fighter design competition that led to the F-15 Eagle in 1970. This engine program was called the IEDP (Initial Engine Development Program) and was funded and managed out of the Aeronautical Systems Division (ASD) at Wright-Patterson AFB. Under ASD, a Systems Project Office Cadre was assigned to manage both the FX Aircraft and Engine definition phase. The Turbine Engine Division of the Air Force Propulsion Laboratory was employed in a support role to assist ASD Systems Engineering in evaluations of technical risks. Later upon selection of the F-15 the ASD engineering cadre became the F-15 Systems Project Office.
The IEDP was created to be a competitive engine design/demonstration phase followed with a down select to one winning engine design and development program.
This brief starts where responsible research should: with the source description of “Pratt & Whitney F100” as afterburning turbofan engine that powers the F-15 Eagle and F-16 Fighting Falcon. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as afterburning turbofan engine that powers the F-15 Eagle and F-16 Fighting Falcon. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 21, 2026. The linked authority identifier is Q1154115. The first chronological checks are 1965, 1967 and 1970.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
