The Northrop MRF-54E was a multirole fighter concept by Northrop in the 1990s.

Development[]

In April 1991, the Advanced Tactical Fighter (ATF) project ended with the YF-22 of the Lockheed team. Although the U.S. Air Force solved the problem of replacing the next generation of main fighters, it was just like its predecessor, the YF-22. The unparalleled performance of the world has also brought high prices that are unprecedented. The U.S. Air Force is bound to follow the story of the light fighter plan and find a fighter with a lower price and excellent performance. As an assistant to the F-22, To replace the F-16, the Multi-Role Fighter (MRF) program was born accordingly.

For the MRF program, the most important of all requirements is that the cost needs to be low enough to provide a large amount of equipment for the U.S. Air Force. The flight cost is between 35 million and 50 million US dollars. Secondly, it must have low detectability ( low-observable characteristics) to improve survivability, and air combat performance also has certain requirements.

As the unfortunately defeated party in the ATF plan, Northrop was unwilling to be defeated and tried to make a breakthrough in the MRF plan, and eagerly proposed two at the Dayton Air Show in July 1991. A MRF configuration. At this time, the military has not even held its first planning meeting. As of 1993, when MRF was cut, the company had proposed 54 configurations.

Among the many configurations, Northrop's MRF design is the most important three. One is the twin-engine design that looks like a reduced version of YF-23. It is scheduled to adopt two IHPTET projects (Integrated High Performance Turbine Engine Technology, integrated The turbofan engine developed in High-Performance Turbine Engine Technology) has a military thrust of 12,000 pounds and a post-combustion thrust of 20,000 pounds. The overall aerodynamic shape is almost the same as that of YF-23. It also uses diamond-shaped main wings and V-shaped tail wings. The fuselage is 16.4 meters long, has a wingspan of 9.44 meters, and a height of 3.2 meters. The overall dimensions are similar to those of the F-16.
