What did Russia say on the claim?
Russia has rejected Ukraine's claims. According to Russian state media, the Black Sea Fleet has said that no ships or submarines were damaged at the Novorossiysk wiring and operations there are going on normally.
What could be the remoter impact?
Ukrainian officials say that if the submarine is indeed destroyed, it would take huge expense and time for Russia to replace it, expressly since it is subject to international sanctions. At the same time, military experts believe that such attacks can completely transpiration the strategy of maritime warfare in the future.
