The Fairchild NF-25 Keeper is a fifth generation fighter jet, primarily used as an air superiority fighter by the Allied States of America. The YF-23 program, by Northrop, was abandoned in 1991, when the United States announced the Lockheed Martin F-22 Raptor would be their advanced tactical fighter. The Allied States readopted the program in 2009. The NF-25 Keeper is expected to entered military service in November 2011 in the Allied States, where it is currently exclusively used and available for foreign purchase.
The NF-25 Keeper is identical to the prototype YF-23 in terms of appearance. However, major differences are that the NF-25 Keeper has stealth-capabilities and will only be available in a lighter shade of grey.
