That's an interesting thought...
We know the Russians have had nearly unlimited access to the F-117 that was shot down - but to claim it was used in the making of the S-400 system is
No doubt the radar absorbent material was studied in depth, certainly the fiber composite structure was scrutinized, but the faceted shape of the
F-117 was ruined when it crashed in a dead flat spin, inverted, and pancaking on impact.
Of course the Russians could feed in the structural dimensions of the F-117 into a cad program and run their reflectivity tests through software sims
or they could build a scale model of the 117 and test it on the test range - but even so, that in no way gives them the data they would need to claim
with any validity that the S-400 can compromise ALL stealth aircraft.
The B-2 is made with different tech than the F-117 and the F-22 is made with 1-2 generations of stealth tech advancement between it and the B-2.
Furthermore, how many times must it be said that stealth technology does not make an aircraft invisible, it simply reduces the range at which it can
be detected. That reduced range when combined with tactically safe corridors and electronic counter-measures does not make a plane invincible - it
just reduces the risk to plane and pilot.
Ok, now for the S-400...
The S-400 is simply an evolution of the S-300, it's supposed to already be deployed around Moscow, St. Petersburg, the Ural industrial complexes, and
some of the southern borders.
Regarding Zaphod58's statement that the US has a copy of the S-400 system; there is no publicly known data confirming that and thus far no S-400's
are known to have been exported out of Russia. Could you have meant the S-300? The US does have several S-300's of varying revision dates.
The S-400's most notable point is unquestionably it's Stealth defeating technology, however there is nothing in the 96L6
radar's specs that describes anything useful to defeating Stealth;
it is very effective against low flying targets and against targets in the
medium and high altitudes even in the presence of heavy jamming, and has a very low false-alarm rate, but the S-400's 96L6 C-band (4-6GHz) unit is
nothing special when facing a low observable aircraft.
Also, the S-400's 40N6 long range missile is still behind schedule and not deployed leaving the S-400 the 40 km range missile or the S-300's SA-20
