Oh really? Then this is odd:
In 2005~06, the PLA Navy (PLAN) received six improved Project 636M (Kilo class) diesel-electric submarines which are fitted with the advanced ‘Club’ anti-ship weapon complex designed by Russian Novator Bureau. The system features the 3M-54E (NATO codename: SS-N-27 Sizzler) subsonic anti-ship cruise missile (ASCM) with a maximum range of 220~300km. The ‘Club’ weapon system is available in two versions: the surface-ship-based Club-N and the submarine-based Club-S, both of which employs unified combat assets – two types of anti-ship cruise missiles and a type of ballistic anti-submarine missile.
The ‘Club’ weapon system includes a number of different variant missiles including the anti-ship variants 3M-54 and 3M-54E1, and the anti-submarine variant 91RE1. It is still not clear which variant the PLAN is operating on its Project 636M Kilo class submarines. The 3M-54E1 is a 300km-range subsonic anti-ship cruise variant similar to the U.S. Tomahawk. The 3M-54E variant with a shorter range is based on the subsonic stage of the 3M-54E1 but use a rocket-propelled second stage which is released 20~60km from the target. This second stage then accelerates to Mach 3 to defeat ship defences. Both missiles in the ‘Club’ weapon complex use a common active radar guidance system and both fly a low-altitude sea-skimming mission profile. The missile is launched from the torpedo tubes of the submarine.
