The Oscar class, Soviet designations Project 949 Granit and Project 949A Antey, (NATO reporting names Oscar I and Oscar II respectively), are cruise missile submarines (SSGNs) designed in the Soviet Union for the Soviet Navy. They are currently in service with the Russian Navy with some of the vessels planned to be modernized into the Project 949AM to extend their servicelife and increase combat capabilities.

The Project 949 submarines were the largest cruise missile submarines in service until the Ohio-class ballistic missile submarines were converted to carry cruise missiles in 2007. They are the fourth largest class of submarines in displacement and length. Only the Soviet Typhoon-class, Russian Borei-class and the American Ohio-class ballistic missile submarines (SSBNs) are larger.

HistoryEdit

The first submarine of Project 949 was laid down in the mid-1970s and was commissioned in 1980. In 1982 an updated and larger version (Project 949A) replaced the earlier version. In total thirteen submarines were constructed. The Oscar class was designed to attack NATO carrier battle groups using long-range SS-N-19 "Shipwreck" anti-ship missiles and targeting data provided by the EORSAT satellite system (via the submarine's "Punch Bowl" antenna).[4][5][6] In the financial problems that followed the fall of the Soviet Union the Oscar class was prioritized by the Russian Navy and when many older submarine classes were retired the Oscar class remained active in both the Northern and Pacific Fleets. As of 2011, five submarines are currently active with several more in reserve or waiting for repairs.

ModernizationEdit

In 2011, it became known the Rubin Design Bureau is working on a new modernization variant, that will primarily include replacement of the P-700 Granit missile system with the newer P-800 Oniks or Kalibr anti-ship/cruise missiles. The modernization is to be carried out by the Zvezdochka and Zvezda shipyards.[7] In September 2015, during a visit to the Zvezda shipyard at Bolshoy Kamen, Russian Defence Minister Sergey Shoygu announced that at least three Oscar-class submarines will undergo repair and modernization to extend their service life by 20 years.[8] The upgraded submarines will be known as "Project 949AM", according to the Russian officials. The cost of the modernization is estimated at RUB12 billion (US182 million) per a submarine.[9]

In September 2016, it was reported submarines K-132 Irkutsk and K-442 Chelyabinsk are undergoing modernization to the Project 949AM.[10] According to the Deputy Prime Minister of Russia Yury Borisov, Russia's Pacific Fleet may get four upgraded Oscar-class submarines armed with Kalibr cruise missiles by 2021.[11]

Project 949 Granit (Oscar I)Edit

 
Project 949

Two Project 949 Granit submarines were built at Severodvinsk between 1975 and 1982 and assigned to the Soviet Northern Fleet. K-525 was laid down in 1975 and K-206 was laid down in 1979. After the construction of the first two submarines, production continued with the improved project 949A Antey. Both submarines of the Project 949 were decommissioned in 1996[12] and scrapped in 2004.[13]

Project 949A Antey (Oscar II)Edit

 
Project 949A

Eleven Project 949A Antey submarines were completed at Severodvinsk, of which five were assigned to the Soviet Northern Fleet. At one stage it had been planned to develop a new fourth-generation follow-on to the Project 949A, but this plan was later dropped. The external differences between the two classes were that the 949A class is about 10 metres (33 ft) longer than its predecessor (~154 metres (505 ft) rather than 143 m (469 ft)), providing space for improved electronics and possibly quieter propulsion.

Some sources speculate that the acoustic performance of the Oscar II class is superior to early Akula class but inferior to the Akula II class as well as subsequent (4th generation) designs.[14] It also has a larger fin, and a seven-bladed propeller instead of a four-bladed one.[15] Like all post-World War II Soviet designs, they are of double hull construction.[16] Similarly, like other Soviet submarine designs, Project 949 not only has a bridge open to the elements on top of the sail but, for use in inclement weather, there is an enclosed bridge forward and slightly below this station in the fin/sail. A distinguishing mark is a slight bulge at the top of the fin. A large door on either side of the fin reaches this bulge. These are wider at the top than on the bottom, and are hinged on the bottom. The Federation of American Scientists[15] reports that this submarine carries an emergency crew escape capsule; it is possible that these doors cover it. The VSK escape capsule can accommodate 110 people.[17]

Project 949AMEdit

New modernization variant first announced by the Russian Defence Ministry in 2011.[7] The modernization includes replacement of the 24 P-700 Granit anti-ship missiles with 72 newer P-800 Oniks or Kalibr anti-ship/cruise missiles. No design changes to the hull will be required as the missiles will fit into the existing launchers outside the pressure hull. The modernized boats will also get upgraded Omnibus-M combat information and Simfoniya-3.2 navigation systems, as well as new fire-control system, communications, sonar, radar, and electronic intercept equipment.[9] The modernization aims to bring the submarines up to the same technological level as the Russia's next-generation Yasen-class nuclear-powered cruise missile submarines.[8]

Project 09852Edit

In December 2012, construction began on a special purpose research and rescue submarine, designated Project 09852, and based on the incomplete Project 949A (Oscar II class) submarine Belgorod.[18][19][20] The submarine is reportedly designed to carry both manned (e.g. Project 18511 midget submarine) as well as unmanned (e.g. Klavesin-1R) underwater vessels.[19][21] However, while carrying smaller unmanned underwater vehicles (UUVs) would be possible as-is on an Oscar-class hull, the accommodation of a midget submarine such as Project 18511 Paltus or the even larger Project 10831 Losharik,[22] would probably require a major hull extension in order to accommodate a docking compartment. For example, the length of the submarine BS-64 Podmoskovye was increased by 9 metres (30 ft) even though the SLBM missile compartment was completely removed.[23][24]

Belgorod will be reportedly used as a carrier of the rumored Poseidon (NATO reporting name Kanyon) nuclear-powered, nuclear armed unmanned underwater device capable to carry a 100 Mt nuclear warhead, with six such devices being carried horizontally (on each side of the submarine) in place of the 24 P-700 Granit (SS-N-19 Shipwreck) launchers for a total yield of 600 megatonnes.[21][25][26][27]

It is estimated that Belgorod will be 184 metres (604 ft) long which would make it the longest submarine in the world.[21][28][29]

On 23 April 2019, Belgorod was floated out of a slipway during a ceremony at the Sevmash shipyard, watched by the Russian President Vladimir Putin via a TV-link. Further work will be completed afloat and the submarine is scheduled to start its factory and state trials in 2020 after it will be delivered to the Russian Navy.[30][31]
