about 350 km's. That is a rather long distance. Say if the Typhoon is double as stealthy as a standard fighter back then then it would still be
dectected at 175 km range.
The stealth doesn't work that way. Just because F-22 has 0.01 RCS doesn't mean it can be detected at 100 times less range that 1m2 RCS plane. What
does it mean? (please not that I don't remeber accurate numbers, these are inacurate, just for example).
Lets say you can detect plane with 3m2 RCS at 300km. THe 2m2 plane will be detected at 150km2, 1m2 100km, 0.5 m2 70km, 0.1 30km etc.. As you see the
detection range of 0.5 is not 5 times more than of plane with 0.1 RCS. The closer you are the more difficult it is to achieve stealth.
Now Typhoon VS Tomcat. The EF has worse radar (although very capable for it's size)., but is RCS is also much lower, that's the reason why I think
the BVR fight they will have roughly equal oportunities. The Phoenix would be advantage if the detection range is over 100km.
Tomcat VS Su-30 is a different story. Su-30 RCS is quite high, and I think that Tomcat would win in this case.
Many people ask why US is not developing replacement for the Phoenix. I think it is not necessary, simply because even nonstealth future planes will
have much smaller RCS, so the BVR engagements will take place within 100km range - which future advanced Amraams can achieve. The only way how to use
Phoenix alike misilles would be close cooperation with Awacs/Hawkeye.
Edit some exact numbers regarding RCS vs det. range -
F-14A/B radar is able to detect B-52(100sqm) at 200nm, a MiG-21(5sqm) at 115nm, and cruise missiles(0.1) at 65nm. It looks like F-14 will be in fact
able to win the fight VS Typhoon, when estimated Typhoon RCS is 0.5 sqm (clean). That means it will be able to detect it at 80-90 miles still enough
to use it's Phoenix misilles with 100nm range, while Typhoon can carry only Meteors (at best).
I was looking for Su-30 RCS and found sources where it is stated to be 10sqm (but russians were trying to reduce it with low cost stealth) so I think
even if Su has more capable radar then Typhoon, Tomcat still wins...
