Summary: The U.S. maintained unrivaled aerial superiority with its fifth-generation F-22 Raptor for many years, but now faces increasing competition from China and Russia. Both nations have developed their own fifth-generation fighters, the Chengdu J-20 and the Sukhoi Su-57, and are pushing rapidly into the sixth-generation with programs like China's NGAD.
-These programs aim to match or exceed the capabilities of U.S. aircraft with advanced features such as stealth, high maneuverability, and sophisticated radar evasion.
