with that said, the 40N6 missile that the S-400 can use as a range of 400km. — Preceding unsigned comment added by 85.246.17.71 (talk) 00:22, 9 November 2012 (UTC)
Range as a measure is stupid you are better off posting the max output power, and the receivers sensitivity, seriously the lack of understanding shown on this page is stupid. — Preceding unsigned comment added by 173.230.79.158 (talk) 18:06, 1 March 2018 (UTC)
I am disputing this thing's capability to detect and engage stealth aircraft and am removing the statement until verifiable information on the subject is found. Jtrainor 22:07, 3 June 2006 (UTC)
I am disputing the ability of stealth aircraft to be effective against new radars until proven otherwise. Please provide evidence that stealth works. So far, with S-125 being able to intercept F-117, it is very possible that S-400 with newest radar with 600 km range detection can detect and intercept stealth aircraft. Why should we believe that americans are always saying truth and russians are saying lie ??? Clearly biased thinking. did americans aquire any russian radars to tests Stealth aircraft against them? No. did russians aquire stealth aircraft to test their radars against it? Yes. Pavel.
It definitely should be mentioned, perhaps it could be worded differently. It could say "The S-400 is claimed to possess advanced capabilities for detecting and engaging low RCS aircraft.", or something similar. "Stealth" aircraft are nothing magical, they simply have a much lower radar cross section than conventional aircraft, it was only a matter of time before extremely powerful radar systems came out that could detect them, or other methods to detect them were developed and integrated with SAM systems. And considering the S-400 is a continuation of the S-300 series, which although like most modern military equipment isn't combat proven, is very widely regarded to be the most advanced in the world, I don't doubt that the S-400 has at least some ability to detect and destroy "stealth" aircraft.I think that the sentence I suggested is objective and appropriate, so I am going to include it in the article. --Skyler Streng 18:36, 15 June 2006 (UTC)
Someone changed the "claims to be able to" into "highly capable of". This is POV as there has NOT been a case of an S-400 shooting down a "stealth" aircraft. I'm changing it back. CAS 117 00:55, 16 June 2007 (UTC) CAS_117
