The Club is already in service with the Indian and Chinese navies-in submarine and shiplaunched variants.
I did some googling. No footage or photos of an actual Club-K missile. If it has existed awhile in ship-sub-launched versions then it must have another name as well. Is it a new version of the existing SS-N-19/P-700 missile, as carried on the Kirov class surface ships and Oscar class submarines?
