The F404 Engine Family

The F404 Family

Proven Performance

The F404 engine proves its performance every day as it continues to power front line fighters for armed forces around the world. The F404 was designed as a replacement for the J79 with roughly the same thrust, but at approximately two thirds the size.


Engine Overview

The performance and reliability of F404 engines have set the standard for modern fighter engines. The engine family powers multiple aircraft performing a broad spectrum of missions from low-level attack to high-altitude interceptors.

The combat-proven F404 has accumulated more than twelve million engine flight hours serving the U.S. Navy, Marines and Air Force, as well as the military forces of Australia, Canada, Czech Republic, Finland, India, Indonesia, Kuwait, Malaysia, Singapore, Spain, Sweden, Switzerland, South Korea and South Africa.

The F404 participated in experimental programs with the Grumman X-29 and MBB X-31.

The world's first operational stealth fighter, the Lockheed Martin F-117A, was powered by a non-augmented version of the F404. The U.S. Air Force first flew the F-117A in 1981 and the fleet was retired in 2008.

In the mid-1970s, the U.S. Navy and Marine Corps chose the F404 to power their basic fleet fighter and attack aircraft, the McDonnell Douglas F/A-18.

In addition, Sweden selected the RM12, an upgraded F404 in partnership with Volvo, to power its new, all-purpose fighter, the Gripen.

Today, the F404 is the standard for modern fighter aircraft offering performance, simplicity and multi-mission capability.
