Interesting reports..
The first one shows American VICE media "JOke" of whether US should launch a Nuclear
attack on Russia now that the early warnings satellites are out of service.
Vice News: Now Is The Time For Nuclear War With Russia?!http://russia-insider.com/en/vice-now-would-be-pretty-good-time-nuke-russia/ri8663
The second link explain in more detail.. the question asked before about difference
between Satellite early warning and Radar early warning and how both are better..
but having only radars can do the job..

As you see the information charts.. the most likely attack of Americans in Russia.. in case
they wants to commit suicide and start a nuclear war.. is from the borders of Russia.. right
there withing Norway coast. (WHich Putin Told recently ,that Americans have always parked near the Norway coast Ohio Submarines with Nukes aiming at moscow..) that will take ~17minutes to reach Moscow.. and according to the graphs ,~11 minutes to be detected after launch by Russian early radars.. and about 14 minutes by Satelites early warning system.
So in the most shortest distance.. the difference between early radar and satellite is like 3 minutes extra time. If the missiles launched from US territory Silos, Russia will lose like 15 minutes early warning.. time without satelites ,still they will be detected withing the 10+ minutes before impact by early radars.

So according to Putin , if we are to take his word.. The "freedom Loving" nation of USA...
have permanently deployed nuclear heavy submarines with ICBMS withing the coast of Norway.
that its Trident II missiles can reach Moscow in just ~15 minutes..
Didn't something like this created the CUban Missile Crisis? when Russia deployed Nuclear missiles in Cuba? and now you have the Americans 365 days a year near Russia coast permanently with Nukes? Shouldn't this become a major flagrant security threat against
Russia federation , and justify a very hostile and aggressive stance of Russia.. like flying
with nuclear Bombers near US coast? or sending Submarines near US coast?
Other important info.. by reading the Comments in the Russian Forces.org site..
is that the distance to central Russia where Russia have located many nukes is longer..
should be another 10minutes.. for any US trident missile Attack.
All this reinforce my believe that Russia needs to move their interceptors to space..
Using Kinetic Interceptors.. that way ,any trident attack on Russia can be intercepted
BEFORE it reach Space on its launch fly path. intercepting the missiles withing seconds
they launched.. not 15 minutes or 30 minutes before.
Interceptors could be just Radio electronic weapons ,that jam the guidance of any enemy
missile.. or it could be lazer or EMP attacks to destroy the electronics of the missile , so it
stop working its engines.. or simply a kinetic projectile.
so it does not violate any treaty.. and if Americans move away
from space treaties.. then Russia can quickly arm with nukes those same space defense
satellites.
This also reinforce the need of Russia to have its own space station.. on an orbit that covers all
Russia.. that way Russia will have a God's eye view of Russian territory and will easily see
any Missile either ballitic or cruise missile that move in the direction of Russia territory..
and with Powerful optics Russia will be able to see very close in the ground any enemy movements on the ground.
