The trajectory of fighter aircraft evolution has been a testament to humanity’s relentless pursuit of aerial superiority.

From the pioneering days of jet propulsion to the advent of stealth technology and integrated computer systems, the evolution spans several generations, each marked by transformative advancements.

As we look ahead, the quest for a potential seventh-generation fighter raises intriguing questions about the future of aerial warfare.

The generational designation of modern aircraft stems from the warplanes developed after World War II, starting with first-generation jet propulsion.

Subsequent leaps brought advancements like swept wings, radar technology, and beyond-visual-range missiles in the second and third generations, while the fourth generation introduced agility, sensor fusion, reduced radar signatures, and fly-by-wire technology, propelling the evolution further.
