The United States Air Force and the government agency that funds it are at odds over the fate of the F-22 Raptor.
The Air Force wants to retire the jets to make room in the budget for its replacement,
One little-known fact about the F-22 is that only 123 of them are in the primary mission aircraft inventory.
The remaining F-22 jets serve as training, development, and backup aircraft and are physically incapable of engaging in air combat.
Most F-22s are less than 16 years old, but the plane's development dates back to the 1980s' Advanced Tactical Fighter programme.
The F-22 was designed to take off from well-established bases in Western Europe and compete against Soviet fighters.
The United States, which was once the sole provider of fifth-generation stealth fighters, now faces competition from Russia's Su-57 "Felon" and China's J-20.
