Stealth fighter effectiveness in SEAD , DEAD

F-35 are first declared to have frontal RCS of a golf ball , about 0.0015 m2 , F-22 are declared to have frontal RCS of a marble , about 0.0001 m2

however according to an interview recently with gen Mike Hostage it reveal that

Both F-22s and F-35s will be spotted at range by low frequency radar. The F-35′s cross section is much smaller than the F-22′s

“The F-35 doesn’t have the altitude, doesn’t have the speed [of the F-22], but it can beat the F-22 in stealth.

Bear in mind that the F-35 is the first US aircraft designed to the requirement that it be highly effective at neutralizing S-400 systems and their cousins

so i think F-35 RCS may be 0.0001 m2 or closer to that rather than 0.001 m2 , that may be due to the improvement of the material being used thus allow LM to excess their requirement.

Firstly in theory radar range will reduced by 44 % when aircraft RCS reduced by 10 times
Range of some very strong radar system vs F-35 in theory ( no jamming , clutter ..etc )
1- SMART-L
are said to be able to detect LO target with RCS = 0.001 m2 from 65 km so the F-35 ( rcs = 0.0001 m2 ) will be detect from 36.4 km

2- SPY-1D ( Aegis ship radar )
can track golf ball-sized targets ( 0.001 m2 ) at ranges in excess of 165 km so the F-35 ( rcs = 0.0001 m2 ) will be tracked from 92.4 km

3 – 67N6E GAMMA-DE ( s-400 radar )
the best version can detect target with RCS = 0.1 m2 from 240 km so the F-35 ( rcs = 0.0001 m2 ) will be detected from 42 km

4-59N6E Protivnik GE 3D Surveillance Radar ( S-400 radar )
can detect target with RCS about 1 m2 from 340 km so the F-35 ( rcs = 0.0001 m2 ) will be detected from 33 km

5- Tor-m1 ( short range air defense )
can detect and track up to 48 targets (minimum radar cross section of 0.1 square meter) at a maximum range of 25 km so the F-35 ( rcs = 0.0001 m2 ) will be detected from 4.3 km

6- IRBIS-E ( Su-35s , may be PAK-FA in future )
detection range for targets with RCS=3m2 is 350-400 km , spot super-low-observable targets with RCS = 0.01 square meters at ranges out to 90 kilometers so the F-35 ( rcs = 0.0001 m2 ) will be detected from 39 km

7- Zaslon-M ( Mig-31 radar ) detection range of 400 km for 20 m2 RCS so F-35 ( rcs = 0.0001 m2 ) will be detected from 22 km

the most common SEAD , DEAD weapons for F-35 , F-22 will be SDB , SPEAR with range of about 100 km , do you think that long enough ? , is it necessary to develop SEAD missiles with longer range , or small stealth missiles
Btw some fighter radar seem incredibly strong even when compared to ground system
