I believe Klub is subsonic missile.It only has a terminal warhead which flies at high supersonic speed for only 30-40 kms max.
A bit of history is needed... in the 1980s the Soviets had two subsonic nuclear armed cruise missiles... one was the Kh-55 and Kh-55SM land attack cruise missile used by the Russian air force... the latter with extended range using saddle fuel tanks to extend range.
The other was the SS-N-21 Granat, which was a different missile but basically of the same performance and use... subsonic all the way with accuracy of about 200-250m CEP which meant nuclear warhead was manditory.
During the 1990s they improved guidance and other parameters and by 2000 they were testing the Kh-101 and Kh-102 which were much longer ranged (5,000km) and much more accurate (less than 20m CEP) which allowed the two models... one nuclear armed and one conventionally armed.
The terminal guidance systems were accurate enough to allow conventional payloads to be effectively used so the guidance system was applied to the older Kh-55 to create the Kh-555 conventional cruise missile.
In the case of the naval missile the problems were multiplied because subsonic all the way just wouldn't cut it any more so they adapted the design of a failed cruise missile called Alpha that was supposed to fly most of the way at subsonic speed and then fly the last few hundred kms at high altitude at high speed... this was genius because a missile able to fly thousands of kms at supersonic speeds would be enormous... the size of a fighter aircraft or bigger. By having a subsonic carrier and supersonic terminal phase it was like the missile was an aircraft and the payload was a missile on that aircraft... but that aircraft could be launched from a sub or ship.
The result was Kalibr... the domestic name for the export Klub.
Kalibr in the subsonic all the way version is just an upgraded Granat long range subsonic cruise missile (not to be confused with the 7 ton supersonic Granit), the Kalibr with the mach 2.9 terminal model is also Kalibr, and both have much longer flight ranges than their export Klub models.
The subsonic Kalibr likely has a flight range of 2,500km, while the supersonic model probably flys 1,350km or so at subsonic speeds with the last 100-150km at supersonic speeds, or at low level the last 50km at supersonic speeds.
Klub is the same family of weapons but with flight range severely reduced to meet export restrictions.
There are also two other missiles in the family... both ballistic rockets that deliver torpedoes at mach 2.5 to distant submarines... one is for sub launch and the other is for surface ship launch.
The kalibre is high supersonic throughtout its trajectory.That is it flies thousands of kms upto 2500 KMs in high supersonic mode.
It may be 1 km/sec or 2.8 mach.
Thats why there is some confsuion as what constitues klub or Kalibre.
Kalibre is presently not given fro export.It s range is beyond MTCR regulations.
What propulsion allows this missile to fly thousands of kms at mach 3?
Granit weighs 7 tons and is rather large and can only manage about 600km at mach 2.5...
The 3M-80 MOSKIT is high supersonic , quick reaction missile.It is now deployed in all Russian missile ships whether small or big.
No it isn't deployed widely. It was on the Sovremmeny class destroyers and a few light patrol missile boats. In its original version its range was 120km, though its max height was 300m and for the rest of the flight it flew at less than 7m above the water. In the improved upgraded model it had a range of about 300km. The original model weighed about 4.5 tons.
It is being replaced by Onyx.
The other thing is UKSK is now basically promoted as export launcher because Russian Navy is NOT showing interest in it.
The reasons have been discussed here.
Name one new Russian surface ship without UKSK.
All the Corvettes and Frigates will have them and the destroyers too.
It is part of the upgrade for the Kirov class ships with the 20 vertical Granit launchers being replaced with 10 UKSK launcher bins (ie 80 tubes).
The Oscar class vessels are having their Granit tubes refitted for UKSK tubes, and I suspect the Slava upgrade will result in the Vulkan tubes being removed and replaced with angled UKSK launchers.
i THINK uksk is alllowed to be deployed only from Pr 885 first submarine but it may be deployed in various corvettes under construction now.
Onyx outperforms Moskit in every parameter, Granit is out of production, Vulkan is not standard and old... the only option is UKSK launcher bins.
For now with Kalibr and Onyx, but later to add the Zirconium hypersonic missile.
UKSK is being exported because it is the only new cruise missile launcher they will have in service soon.
