X-31

The X-31 was an experimental fighter jet developed by the United States in the 1990s to test advanced handling and agility features. It combined traditional aircraft design with innovative control systems, including thrust vectoring— adjusting engine exhaust direction — to improve maneuverability at high angles of attack. This made the jet more responsive and capable of complex maneuvers in combat scenarios. The X-31 served primarily as a test platform to explore new aerodynamic and control technologies, contributing valuable insights to future fighter aircraft design, though it was not intended for mass production or operational use.
