We dont know the true stealth performance of all stealth fighter jet, but we know that both US and China has spent much more money and talent to develop 5th gen fighter than Turkiye.
KAAN platform and RAM paint are excellent for stealth capability
We are waiting for next gen national turbofan Engine for true 5th gen capability as like F-35
You're comparing apples to oranges, F35 is medium weight jet, whereas your KAAN/Su-57/J-20/F-22 are heavy weight jets, compare your KAAN with J-20/F-22 not with F35
F-22 has also 2 x 35.000 lbf Engines
but F-22 lacks IRST , EOTS , HMDS , DIRCM , 360° situational awareness
KAAN Fighter Jet
1-- new turbofan Engine from TR-MOTOR for 5th gen capability
2-- with AI-enhanced battlefield awareness ( 360° situational awareness with 4 AESA radars - sensor fusion with EOTS , IRST with unique configuration )
3-- high-capacity networking , AI, data fusion
4-- Artificial Intelligence Co-pilot
5-- Pilot Health Tracking
6-- DIRCM Directed Infrared Countermeasure System by high power LASER
7-- HMDS (Helmet Display System) with AI-enhanced battlefield awareness
8 --Increased-range BVR Missile (GOKHAN ramjet powered long range networked a2a missile )
9-- excellent EW capabilities with ASELSAN FEWS -- Fighter Electronic Warfare Suite
10 -- full data-to-decision (D2D) capability for multi-layered distributed team of diverse manned aircraft working in concert with unmanned types ( KAAN , ANKA-3, KIZILELMA )
