Its a Shkval-E, clearly visible from the pictures. In the report it was also said that the Torpedo will be launched from stealthy platforms which have to get close to the target (likely about 10km). Other than the "multiple warhead" missile, this one was not said to be an indigenous achievement.
Maybe a new license production of the Shkval-E.
