If you have not read it yet, please check out Putin’s full address to the Federal Assembly.  What stunned me, and many other, are the new weapon systems Putin has announced.
First, he confirmed that the Sarmat ICBM would replace the old but already formiable SS-18 “Satan”.  Then he turned to new weapon systems:
  1. A nuclear powered cruise missile with basically unlimited range
  2. A nuclear powered unmanned submersible with intercontinental range, very high speed, silent propulsion and capable of moving a great depths
  3. A Mach 10 hypersonic missile with a 2’000 kilometer range (named: Kinzhal)
  4. A new strategic missile capable of Mach 20 velocities (named: Avangard)
All of these systems can be armed with conventional or nuclear warheads.  Just think of the implications!  Not only does that mean that the entire ABM effort of the USA is now void and useless, but also that from now US aircraft carrier battle groups can only be used against small, defenseless, nations !
Right now I simply don’t have the time to write a full analysis of the stunning, truly tectonic, implications of this announcement, so I will turn to my naval warfare expert friend Andrei Martyanov and repost his initial reaction to just one of these systems:

It Is Official And It Is Over.

While the whole Western media are shaking (incompetence will do this to one) in their boots from Vladimir Putin’s address, where he demonstrated, among many things, new RS-28 Sarmat ballistic missile, behind that revolutionary weapon system, one was almost completely ignored by media. Again, “education” based on catch phrases (such a “nuclear weapon) will do this to one. By far most shocking (albeit inevitable) revelation was deployment of a new hyper-sonic missile Kinzhal (Dagger) to regular service with front line Air Force units in Southern Military District. Mig-31 carries this weapon, I am positive any SU-35 or SU-30SM or SU-34 will be able to do it too. Here is a video and CGI simulation. 
The missile is… well, for the lack of better word, is stunning–it is M=10+ highly maneuverable missile with the range of 2000 kilometers. The naval warfare as we know it is over. Without any overly-dramatic emphasis–we are officially in new era. No, I repeat, NO, modern or perspective air-defense system deployed today by any NATO fleet can intercept even a single missile with such characteristics. The salvo of 5-6 of such missiles is a guaranteed destruction of any Carrier Battle Group. 
The mode of use of such weapon, especially since we know now that it is deployed (for now) in Southern Military District is very simple–the most likely missile drop spot by MiG-31s will be international waters of the Black Sea, thus closing off whole Eastern Mediterranean to any surface ship or group of ships. It also creates a massive no-go zone in the Pacific, where MiG-31s from Yelizovo will be able to patrol vast distances over the ocean. It is, though, remarkable that the current platform for Kinzhal is MiG-31–arguably the best interceptor in the history. Obviously, MiG-31’s ability to reach very high supersonic speeds (in excess of M=3) is a key factor in the launch. But no matter what are the procedures for the launch of this terrifying weapon, the conclusions are simple:
1. It moves aircraft carriers into the niche of pure power projection against weak and defenseless adversaries;
2. It makes classic CBGs as main strike force against peer completely obsolete and useless, it also makes any surface combat ship defenseless regardless its air-defense capabilities. 
3. Sea Control and Sea Denial change their nature and merge. Those who have such weapon, or weapons, simply own vast spaces of the sea limited by the ranges of Kinzhal and its carriers. 
I don’t want to sound dramatic and I knew that there were and are always surprises in Soviet/Russian weapons but today’s revelations from the highest podium in Russia about Kinzhal were shocking. The balance of power just shifted dramatically, with it the naval warfare as we knew it is no more. It is OVER! 
I can only add that I fully concur with him.  It is indeed set, match and game over for the Empire: there is no more military option against Russia.
