This infographic shows EOTS + 2 external cyindrical pods, which has created massive public confusion.
EOTS = LD + IRST.
Some say it will be jammer, some say it can be DEW pod. Either ways it can be given hexagonal shape for stealth with RAM, RAS.
Turkey, China are way behind USA in materials. As per documentaries, interviews, podcasts, etc, SR-71 is said to be gen-1 stealth with shaping & RAS, F-117 is considered gen-2 stealth, B-2 is considered gen-3 stealth, F-22/35 are considered gen-4 stealth, B-21 & NGAD are gen-5 stealth. This gen is only for stealth aspect, not for entire jet.
USA may also have evolved from usual layered paint approach.
But in everyday life we see most features, quaity = more cost.
The RAM paint might be costly to maintan but it also certainly contributes to reduce RCS, hence R&Ded & invested upon. Those nations who can't afford is their bad luck, just like there the citizens may not have cars & other stuff like Western people.

But no matter who does what, ultimately the RCS return numbers matter.
F-22 has RCS= 0.00015 sqm.
F-35 has 0.0015 sqm.
Let's see AMCA's RCS tested & quoted in future.
