Club-K - Container Cruise Missile

"Barabanov said the Club-K used proven missiles from Novator, an established Russian maker of weaponry including anti-submarine, surface-to-air and submarine-launched missiles.

One of the missiles on offer is a special anti-ship variant with a second stage which splits off after launch and accelerates to supersonic speeds of up to Mach 3.

“It’s a carrier-killer,” said Hewson of Jane’s. "If you are hit by one or two of them, the kinetic impact is vast…it’s horrendous. "
