OK! Good to know. Do you have the names of the missiles that the S-500 will use?
No idea... not many people actually know.
Don't know whether it is single or two stage... has been said it will be a new missile and not based on S-400, though it may operate with S-400.
If it's true that A-235 will be mobile then I am not sure what purpose the S-500 will serve? My guess is that the A-235 will be used for exo-atmospheric interception & if that fails then the S-500 will be used for endo atmospheric interception.
Nudels missiles will be truck based and likely mobile but the radars and infrastructure needed to use them will likely be largely fixed.
Think of S-400 as being Patriot/THAAD and S-500 being PAC-3/THAAD-ER, while Nudol is getting close to being a dedicated anti sat and anti ICBM system...
Except that S-400 can deal with a wide range of targets including those travelling at 4.8km/s, while S-500 will be able to deal with targets travelling at 7km/s and some low orbit objects, while Nudel will be able to hit incoming ICBMs and satellites in low and possibly medium orbit too.
Well all that is an evolutionary process.
S-300P was alway (in every version) not that what was expected. But Almaz (and Sukhoi) was supported in the Yelzin era. Antey (and MiG) fell short. But the Antey System (S-300V) had always the better potential in its design parameters and came closer to both a long range anti aircraft system with the ability to intercept IRBMs.
The desperate struggle to turn the S-300P finally into the weapon which was needed ends up in the S-400 (with 40N6, better SW and Radar) and in the S-350, which finally will bring up the 9M96 already promised for S-300P.
After establishing Almaz-Antey it was clear that the real successor to S-300V will not be stopped at V4 but come up with the S-500.
Up to now we didn't know much about the 40N6. Does it fit really into the same container like 48N6? Or is it a step forward to a longer missile which will materialize in one of the missiles for S-500?
I think it is fair to assume that the missiles for S-500 will more derive from 9M82 than from 48N6. One seems for sure. The improvement in Radar, SW, and a 9M82 follow on will provide the S-500 with a true IRBM defence capability which S-400 don't have.
About ASAT/Nudol and A-235 there is also a lot of guessing. Some sources say both systems are the same. If you have a capable long range ABM you also can kill satellites (SM-3). But who knows. It is believed that A-235 will be stationary. But a new long range variant (as successor to 51T6) was never tested. Just the 53T6 was improved an Don-2N. Is that already "A-235"?
And if so, is this complemented by a mobile system which was presented on the Almaz-Antey calender picture? A "mobile" system which is supported by a stationary Radar at Chekov? Does this make sense? Or does that Almaz picture just show a variant of S-500?
Well time will tell
