But still there is a problem how tiny RF seeker of the missile engage on stealth material while FCR can guide?
Moreover İ doubt the numbers ( 30km/60km).
No one could know it except Americans.
First you should have a F-35 to examine it.
Well sir! As you suggested, for examination I am gonna order an f35 on amazon! Just kidding. My calculation simlpy based on oficial press released information of both f35 and aselsan's STR. ( that's as far as i can get )
so firstly, f35 isn't all band stealth. Some fan boy gonna claim that. but that's not correct. Out side the S and X band domain f35's low observablity ( or for that matter, any stealth fighter's low observability ) decrease. So, the US Air Force's official press release about f35's RCS being size of a golf ball which mean 0.0015 is mostly related to S and X band domain.
Remamber, all the fire control radars siting on the noses of fighters are X band. And in case of ground based fire control radars they are also mostly between X and S bands and lately there are some are C band. ( note, I am not talking here about target illumination radars ).
Now let's talk about siper, 'tiny' ku band seeker can acquire low observable target if there is a two way data link which can guide the interceptor until the very last moment. ( So this isn't a big issue. And I think siper has a two way data link ) and also, in the future blocks siper is likely to gain a ka band seeker just like the one on aster 30 block 1nt. Which is very useful in acquiring low RCS targets.
Now, about STR ( on which FCR is likely to based on ) it can detect a Katyusha-type artillery rocket from 100km according to the defenceturkey.

now, katyusha is 122mm rocket with a typical RCS of 0.1m. So when we do the math with f35's RCS to determine the detection and tracking range with fourth roots calculation, it is important to remamber that f35's said RCS ( 0.0015 ) is not all aspects but a frontal one. ( which is very useful against another fighter in head to head mode )
However, when the ground based FCR looks at f35 from a below Angel some surface area on the jet will be exposed which has less RCS than frontal section. And It is likely to be then somewhere in between 0.008m and 0.05m. So when we do the math based on that the detection and tracking range of an f35 for FCR will be somewhere in between 60 to 80 km.
Note, this is my personal opinion based on my personal knowledge. So don't take it too seriously and please do not accuse me of disinformation.
