Russia’s latest super-sized submarine, Belgorod, has been a conundrum for interested observers. While its existence is far from secret, Moscow has gone to great pains to keep certain key details out of the public domain. While navies traditionally hide the screw, or propeller, from the cameras, in Belgorod’s case the reverse was true: the screws were on display at the 2019 launch ceremony, but no photographs of the forward section were ever published.
Belgorod’s secret is its arrangement of the primary weapon system: a new class of nuclear-tipped torpedos. Russian state media Izvestia reported on Feb. 11 that Belgorod is being prepared for tests with the new weapon called Poseidon, a massive nuclear torpedo which is shot forward out of the front of the submarine.
