The General Electric F414 is an American afterburning turbofan engine in the 22,000-pound thrust class produced by GE Aerospace. The F414 originated from GE's widely used F404 turbofan, enlarged and improved for use in the Boeing F/A-18E/F Super Hornet. The engine was developed from the F412 non-afterburning turbofan planned for the A-12 Avenger II, before it was canceled.
