Fifth-generation fighter aircraft are defined by characteristics such as stealth, supercruise, advanced avionics, and highly integrated digital systems. The Rafale is a 4.5-generation aircraft, known for its advanced capabilities but lacking full stealth features. The MiG-29, while a capable fighter, belongs to the 4th generation. The Tejas MK-1 is an indigenous 4.5-generation aircraft. None of these aircraft meet the stringent criteria for being classified as fifth-generation fighters.
