If he's armed with Zircon it's quite possible. A volley of several Zircon can sink an aircraft carrier and some destroyers. Currently, the aircraft carrier group is unable to defend itself against this missile. Zircon completely changes the rules of the game.
The point is though that he wont, because the direct result of a ship sinking a US carrier battle group will be the start of WWIII, which he can't do much about and really does not benefit from at all.
It is like saying I can stab you in the eye and kill you... so what... I am not going to...
Well perhaps I would not be suggesting a longer ranged ASHM if the tomahawk did not outrange the Zirkon the tomahawk last time I checked had more than twice the Zircons range meaning that a Russian ship would get overwhelmed by them before it could get in range to fire its zircons.
Please tell me at what range a Tomahawk cruise missile can sink and Oscar Class SSGN?
You don't think Russian carrier groups or frigates are going to be hunting US carrier groups do you?
Why do you think Oscar and Oscar II and Yasen class subs exist for?
Obviously a Russian carrier group will be equipped with weapons to allow it to fight carrier groups, but why do you think they would go out of their way to do so?
It is like saying the BMP is a tank killer... they carry anti tank missiles to defend themselves but it is only a defensive thing... most of the time the wont take on enemy MBTs if they can help it... Russian tanks are better equipped for that job... and anti tank units with ATGM missile vehicles like Shturm and Kornet and Krisantema are intended for that job... usually in conjunction with a minefield and other preparation.
How clear do I need to make this?
You are not doing very well... why does Russia need longer ranged anti ship missiles so a small missile corvette can defeat the entire US Navy.
Will you keep the Russian Army and Air Force to the same standard... one tank to take out all of HATO and one fighter plane to shoot down every western fighter ever made?
Russian corvettes wont be sailing the worlds oceans... especially in times of tension... they will have an umbrella of protection from land base air power and missiles stretching out about 2,000km thanks to MiG-31s and Kinzhal.
Kinzhal is a simple basic solid fuelled rocket launched from the high ground at high speed from a MiG-31... so a scramjet powered upgraded model should be orders of magnitude better in terms of speed and range.... and in 5 years time when the first MiG-41s are entering service with a flight speed of mach 4.2 these new long range missiles... perhaps based on a ground launched missile that would have been banned under the INF treaty but will be perfectly legal will have even better performance...
The Buyan M cannot provide area air defence, it would either be used as a missile boat with the help of reconisance assets or as a sea mobile Kalibr launcher.
Soldiers armed only with Makarov Pistols are not normally tasked with providing squad support fire power... that is why soldiers with RPK-74s and SVDs and PKMs are in the group for.
Name a single HATO corvette that could provide area air defence?
USA needs to throw at least ten tomahawak against each Buyan corvett to have slight chance, most likelly the optimal number is closer to 20 .
And that is important because it puts their capacity to carry large numbers of anti ship missiles in to perspective.
It is also important to point out that a single Buyan could engage quite a few subsonic low flying missiles... its jammers and decoys could deflect the attention of quite a few more, but if it is near other Russian ships they can actually work together so the sensors on the Buyan will be able to detect and track vastly more targets than its air defence systems will be able to engage at one time... but 40km away there could be a bigger ship with Redut and 150km range 9M96 missiles that can be fired in large numbers to help out... a quick satellite link could communicate to nearby Russian naval vessels and aircraft that an attack was in progress and information from land based over the horizon radars might identify the exact moment the attack was launched so the Buyan could start moving closer to other Russian vessels so that mutual support is more effective... meanwhile a dozen MiG-31s are launched with a single Zircon each to sink the ships that launched the unprovoked attack...
Zircon was listed at over 1000km range according to what Putin quoted.
I would suggest that is most likely the range of the model with a conventional warhead.... a nuclear armed model might reach 1,500km which is still very good for a surface launched missile...
Russia could atleast develop a land based version similar to the Chinese anti ship HGV in order to nullify ant attempt at standoff attacks by enemy surface vessels without the need to rely on thier tu22s and 160s.
What makes you think an SSBN couldn't enter the coordinates of a patch of sea and launch an SLBM at a group of ships?
Western ships are no longer the problem they used to be because of their vulnerability to even just Onyx... which is an excellent missile... or the supersonic Sizzler anti ship missile...
