Fifth-generation fighters represent a significant leap in air combat capabilities, incorporating advanced technologies that revolutionize aerial warfare. These cutting-edge aircraft, such as the F-35 Lightning II and the Chengdu J-20, boast exceptional stealth characteristics, enabling them to operate undetected deep within enemy territory. They leverage advanced sensor fusion systems that integrate data from multiple sources, providing pilots with unprecedented situational awareness and enabling them to make informed decisions in real-time. The fifth-generation fighters also employ advanced avionics and highly integrated computer systems, enabling them to communicate seamlessly with other friendly assets, enhancing overall mission effectiveness and interoperability. These fighters are equipped with advanced radar systems, enabling them to detect and track enemy aircraft from long ranges. Additionally, they possess exceptional maneuverability and speed, allowing them to engage and defeat adversaries in both close-in dogfights and beyond visual range engagements. The fifth generation of fighters has set a new benchmark in air combat capability, ensuring dominance in the skies and the ability to project power with unrivaled precision.
'Into service' - defined according to the Wikipedia page for the type
@PontiMin The question will simply follow the consensus of western military analysts on what is fifth-gen in 2035 (or prior, if a claim is made).
At present:
No-one would argue that the Eurofighter is fifth generation
It seems clear that KF-21 is currently not, however future versions might be (but I doubt it personally)
Kaan is claimed to be by Turkey, but I believe the only reason this claim isn't heavily disputed by analysts is a lack of information (I would postpone resolution in this case)
Su-57 has always been considered fifth generation, and I would resolve it as such. There is, however, a slightly growing school of thought that suggests it has been overestimated, so watch this space.
@JoshuaWilkes Then I think the question, as worded, is too vague to answer. I much prefer questions where resolving them can be done on more-or-less objective criteria.
