The Oscar's crew of 107 contains 48 officers. These anti-ship missiles have a range of 550 kilometers, a speed of 1600 kilometers an hour, and a 750 kg (1,650-pound) high-explosive warhead (or a nuclear warhead of 350 or 500 kilotons as an option). They have eight torpedo tubes (four 650mm, four 533mm), and 24 SS-N-19/P-700 Shipwreck missiles. The Oscar II class boats have a surface displacement of 14,000 tons. The original Oscars were designed as "carrier destroyers" with long-range cruise missiles that could, in theory, take out an American aircraft carrier. This time there would be some major revisions that turned Belgorod into something more than an SSGN. Then in 2012 it was announced that the Belgorod, which had not been scrapped but put in “storage”, was once more scheduled for completion. That did not last long because the money was not there and not likely to be in the immediate future. Seven Oscar IIs remain in service, as the Kursk was lost in 2000, to a well-publicized accident. Another $100 million was needed to complete Belgorod and the government (although not the navy) felt it wasn't worth it. But, at that point the navy had run out of the money, with the Belgorod not quite complete. Construction continued on six more, and by 1997, eight were in service. Three were in commission when the Soviet Union disintegrated in 1991. Known in the West as the Oscar II class, these boats began entering service just as the Cold War ended. In 2006 Russia announced it would not finish construction of the Belgorod, the last of nine Type 949A SSGNs. At one point the sub was canceled while still under construction. Belgorod won’t work for the navy like other subs, but for the GUGI (Main Department of Deep-Water Researches) which works for the intelligence services and is attached to the Navy for ship and crew support.īelgorod has come a long way since construction began in 1982. Between 20 Belgorod had special equipment installed and tested before this modified Oscar class SSGN (nuclear-powered cruise missile submarine) was ready for service. After that, nothing (that could be detected). The actual Poseidon torpedoes, which are described as a doomsday weapon, are being built and not expected to be ready for another year or two.īelgorod was launched in 2019 and entered service in mid-2022. The size and weight of the Poseidon attached to the bottom of the Belgorod changes the performance characteristics of the Belgorod and tests were done to note and fix any problems. The dummy Poseidon is the same size and weight of the real one. The Poseidon torpedo is too large to be carried inside Belgorod and launched from a torpedo tube, and are instead affixed to the underside of the sub and released by the sub commander. Belgorod is a larger and heavier Oscar class sub but it still uses the same power plant as the other Oscars. These tests also confirmed that the nuclear propulsion system worked as expected. Russia reported in early January that Belgorod was testing mockups of its primary weapon, the Poseidon torpedo, to make sure they could be carried and launched by Belgorod. Commercial satellite photos showed the Belgorod on the surface off the northeastern Russian coast, where several ports used by the Northern Fleet are located. H I Sutton, a naval analyst who has researched Russia's submarines, told The Barents Observer in 2018 that Moscow had "invested heavily in this secretive fleet, even in times of economic hardship.Russia’s mysterious special purpose 14,000/24,000 ton (on the surface/submerged) nuclear submarine Belgorod (K-329) has shown up again. Yantar also appears to host a number of other manned and unmanned submersibles and to be able to map underwater pipelines and cables. The ship is believed to be able to carry a manned deep-sea submersible that can dive up to 6,000 meters. GUGI has a number of surface vessels, notable among them the special-purpose survey ship Yantar.

GUGI also operates the nuclear-powered special-mission vessel Belgorod, the world's longest submarine, which can carry the smaller Losharik. However, the small size of these specialized undersea vessels limits their range, so GUGI's fleet also includes two nuclear-powered submarines that previously carried ballistic missiles but have been converted to carry other GUGI subs under their hull and covertly deploy them close to their target.

To allow them to sabotage underwater infrastructure, these submarines carry a complement of tools, including manipulator arms and lock-out compartments that allow divers to exit into the ocean. Account icon An icon in the shape of a person's head and shoulders.
