How powerful is the Kalibr Cruise Missile?

The Kalibr missile is a family of Russian cruise missiles developed by the Novator Design Bureau.
The Kalibr missile family includes well over a dozen different variants, each with its own launch platform, range, target profile, and speed, as well as a length ranging from six to nine metres and a 990-pound warhead or nuclear payload.
Russia intends to install KALIBR missiles on all new nuclear and non-nuclear submarines, corvettes, frigates, and larger surface ships.
KALIBR provides even modest platforms, such as corvettes, with significant offensive capability and, with the use of the land attack missile, all platforms have a significant ability to hold distant fixed ground targets at risk using conventional warheads.
