The Russian 3M-54 Klub is a multi-role missile system developed by the Novator Design Bureau(OKB-8). Its NATO reporting name is SS-N-27. Both submarine- and surface ship-launched versions exist. The system is designed to accept various warheads, allowing its use against surface and subsurface naval combatants along with static land targets. In one variant, the 3M-54E (Sizzler), the final stage makes a supersonic 'sprint' to its target, reducing the time the target's defense systems have to react. The 3M-54E1 subsonic missile is roughly comparable to both the American Tomahawk cruise missile and the ASROC missile but is smaller and has a shorter range.
The missile is a modular system with 5 different variants: two anti-shipping variants, one land attack variant, and two anti-submarine variants. The missile is designed to share common components between the surface and sub-launched variants with the only difference being the design of the missile launchers and the containers. An air-launched version is believed to be in development.
'Sizzler' flight 
The Sizzler variant (3M-54E) flies at subsonic speeds while going supersonic as it nears its target. It is also believed to be able to perform very high angled defensive maneuvers in contrast to the common linear flight path of other anti-ship cruise missiles.
There are two major launching vehicles: the Klub-S, designed for launch from submarines, and the Klub-N, designed for launch from surface ships. These two launchers can be equipped by the following warhead and guidance combinations:
3M-54E - Anti-shipping variant, Basic length 8.22 m, with a 200 kg warhead. Range is 200 km. Sea-skimmer with supersonic terminal speed and flight altitude of 15 feet (4.6 m) at final stage(2.9 mach).
3M-54E1 - Anti-shipping variant, Basic length 6.2 m, with a 400 kg warhead. Range is 300 km. Sea-skimmer with subsonic terminal speed(0.8 mach). Allegedly capable of disabling or even sinking an aircraft carrier.
3M-14E - Inertial guidance land attack variant. Basic length 6.2 m, with a 400 kg warhead. Range is 275 km. Subsonic terminal speed(0.8 mach).
91RE1 - Submarine-launched anti-submarine variant, with an anti-submarine torpedo. Basic length 8.0 m, with a range of 50 km. Supersonic speed. The torpedo has a warhead weight of 76 kg. This, along with the 91RE2, are similar to the American ASROC/SUBROC missile/torpedo system. Follows a ballistic path into the surface, speed is Mach 2.5.
91RE2 - Ballistically launched anti-submarine variant, with an anti-submarine torpedo. Basic length 6.5 m, with a range of 40 km Supersonic speed. The torpedo has a warhead weight of 76 kg. For surface ship use only. The lightest of all variants, with a launch weight of 1300 kg. Speed is Mach 2.
Launch Platforms 
The Russian Kilo class submarine is the primary launch platform for the missile. The future Russian Lada class submarine and its variants should also be able to launch the missile. The Indian Talwar class frigate is another primary shipborne launch platform for the missile. The Akula class submarine and the new Yasen class can also launch this missile. The new Russian Admiral Sergei Gorshkov class frigates and the second batch of Steregushchy class corvettes use the same UKSK VLS as Talwar class frigates, and thus would be able to carry these missiles as well.
It is also believed by some analysts that an air-launched variant will be developed to arm the Tu-142s currently in service with both the Russian and Indian Navy, and it is also anticipated that the Tu-22M3 operated by the Indian Navy will also be equipped with the missile. A truck mounted version is also planned for development by the Novator Design Bureau.
A Klub-K variant, which launches from commercial-appearing shipping container mounted on a truck, train, or merchant vessel, was advertised in 2010  and was shown for the first time at the MAKS 2011 airshow 
- Russia: The Russian Navy uses the Klub-S variant for the Kilo class submarine, the Lada class submarine, the Akula class submarine and the Yasen class submarine. Klub-N for the Gremyashchy class corvette, the Buyan-M class corvette, the Gorshkov class frigate and the Grigorovich class frigate.
- Algeria: The Algerian National Navy uses the Klub-S variant for their 4 Kilo class submarines.
- India: The Indian Navy uses both Klub-S and Klub-N variants for the Kilo class submarines (known as the Sindhughosh Class in Indian service), the Shivalik class frigate and the Talwar class frigate respectively.
- Vietnam: The Vietnam People's navy uses the Klub-S variant for the 6 Kilo class submarines.
- China: The People's Liberation Army Navy uses the Klub-S variant for its Kilo class submarines.
- Iran: Contradictory sources indicate that the Iranian Navy is thought to have purchased or is in the process to purchase Klub-S missiles for its 3 Kilo class submarines.
