The performance and simplicity of the F404 has set the precedent for modern fighter engines.  Pilots praise the F404's unrestricted throttle movements, fast response, and smooth afterburner light-off.  The baseline F404-GE400 augmented turbofan engine features innovative diagnostics, conveniently placed accessories, and modular design.  Users benefit from simplified engine maintenance including rapid module assembly/disassembly and elimination of post-maintenance adjustments.  Right hand and left-hand engines are identical with no Quick Engine Change kit required.

F404 engines power McDonnell Douglas F/A-18 aircraft serving U.S. Navy, U.S. Marines and the forces of Canada, Australia, Finalnd, Spain, and Kuwait.  F404-powered Hornets have also been selected for service in Malaysia and Switzerland.

The F404-GE-402 Enhanced Performance Engine (EPE) provides higher power and improved fuel efficiency for increased mission capability. 

Performance improvements were achieved primarily through improved thermal cycle and increased temperature made possible by the latest technology and materials in the turbine and afterburner.  This higher power F404 maintains the 2,000-hour hot section and 4,000-hour cold section life of the proven F404-GE-400.

The F404 engine family powers a broad spectrum of missions from low-level subsonic attack to high-altitude fighter intercepters and technology demonstrators.  Non-afterburning derivatives power the USAF/Lockheed F-117A Stealth Fighter and re-engined Singapore A-4 Super Skyhawk aircraft.  The afterburning F404 RM12 powers the Swedish JAS 39 Gripen and a variant of this engine will power the Indian LCA (Light Combat Aircraft) flight test program.  F404 powered research aircraft are exploring an extended air combat envelope for fighters of the 21st century.
