Putin has launched a major salvage operation to the wreck of the downed Black Sea Fleet flagship to secure military secrets including coding devices, unexploded missiles, and possibly even attempt to bring the bodies of dead sailors back home, naval experts have claimed. An eight-ship salvage flotilla including Kommuna, the world's oldest active warship, and submarine has been sent to the site of the sunken Moskva 80 miles off the coast of Odessa from Sevastopol, the large naval base in Russia-annexed Crimea, according to a report by Forbes.
