(Business Insider) – Russia will deploy what’s been described as the deadliest nuclear weapon ever aboard mysterious submarines by 2020, Russian state media said, citing a Russian defense-industry source. The “Poseidon” nuclear-powered torpedo — reputed to carry a 100 to 200 megaton nuclear warhead and meant to erupt underwater for maximum effect — will reportedly deploy aboard the Project 09852 sub Belgorod,

which is a converted nuclear-powered cruise-missile sub expected to go on combat duty in 2020. The Russian state news agency TASS said the new Belgorod subs could carry six of the Poseidon nuclear torpedoes, which are sometimes described as drones. But Russia will reportedly not operate the mysterious submarine alongside its regular armed forces or other nuclear-powered subs. The Main Directorate of Deep-Sea Research will run the ship, according to H.I. Sutton, who said the Belgorod would conduct covert missions with a smaller submarine in tow. READ MORE
