It looks very similar to an F35, can someone explain how does it work? Is it just a coincidence? Do they end up using the same technology? Is it a modification?

If you have similar requirements (aero and stealth) it’s not weird to have similar looking solutions. I am also sure they looked at general designs of competitors for shapes with reduced radar “footprint”. They are very different other than looks though . Eg kf is a twin engine design and most of the tech is home grown.

You summed up really well. I guess most of the recently developed/developing platforms tend to share familiar looks at a glance, like F35(US), J35(CN), Kaan (TK), KF21(SK, although I thought it looked more like older f22 than f35). Also older F16(US) & F2(JP).

> Also older F16(US) & F2(JP). F2 is directly derived from the F-16, it's not a case of convergent design.

It’s always easier to follow than it is to lead. Especially when leading is so expensive. If someone climbed Everest 100 times before deciding on the best route, you’d naturally probably follow them up that best route.

The same laws of physics that apply in the US, also apply in korea, turkey and china. Thats primarily why the F35, KF-21,TAI Khaan and J35 all end up looking so similar when the engineers tried to balance similar requirements regarding stealth / manoeuvrability / speed / range /payload etc.
