Yasen-class submarine explained

The Yasen class, Russian designations Project 885 Yasen and Project 885M Yasen-M (Russian: Ясень||[[Fraxinus|ash tree]], NATO reporting name: Severodvinsk), also referred to as the Graney class, are a series of nuclear-powered cruise missile submarines designed by the Malakhit Marine Engineering Bureau and built by Sevmash for the Russian Navy. Design work commenced in earnest in the 1980s with the first submarine built in the 1990s–early 2010s with commissioning in 2013. Two additional boats to an upgraded (and slightly shorter overall) Yasen-M design were commissioned in 2021 and six more are under construction.[1] [2] Based on the and designs, the Yasen class is projected to replace the Russian Navy's current Soviet-era nuclear attack submarines. The Akula class is optimised for a hunter-killer role, whereas the Yasen class concept uses the platform as a nuclear guided missile submarine (SSGN).[3]

History

The Yasen-class submarines were designed by Malakhit, which was formed through the late 1950s merger of the SKB-143 and TsKB-16 design bureaus. Work on the initial design was scheduled to start in 1977 and be completed in 1985.[4] Malakhit is one of the three Soviet/Russian submarine design centers, along with Rubin Design Bureau and Lazurit Central Design Bureau.

Construction on the first submarine started on 21 December 1993, with its launch slated for 1995 and its commissioning for 1998.[5] However, the project was delayed due to financial problems and it appeared during 1996 that work on the submarine had stopped completely. Some reports suggested that as of 1999 the submarine was less than 10 percent complete. In 2003 the project received additional funding and the work of finishing the submarine restarted.

In 2004 it was reported that the work on the submarine was moving forward, but, due to the priority given to the new Borei-class SSBNs, the lead unit of the class (Severodvinsk) would not be ready before 2010. In July 2006 the deputy chairman of the Military-Industrial Commission, Vladislav Putilin, stated that two Yasen-class submarines were to join the Russian Navy before 2015.[6]

On 24 July 2009, work commenced on a second submarine, named Kazan. On 26 July, the Russian navy command announced that starting in 2011, one multipurpose submarine would be laid down every year, although not necessarily of this class.

An August 2009 report from the U.S. Office of Naval Intelligence estimated the Yasen-class submarines to be the quietest, or least detectable, of seagoing Russian and Chinese nuclear submarines, but said they were still not as quiet as first-line U.S. Navy submarines (i.e. Seawolf and Virginia classes).[7] [8]

In April 2010, it was reported that the 7 May launch of the first boat had been postponed due to "technical reasons".[9] Then, the launch of the first submarine and the beginning of sea trials were scheduled for September 2011.

On 26 July 2013 the third submarine, named Novosibirsk, was laid down.

On 30 December 2013, Severodvinsk was handed over to the Russian Navy. The flag-raising ceremony was held on 17 June 2014 marking its introduction into the Russian Navy.[10]

In October 2014, one of the U.S. Navy's top submarine officers, Rear Admiral Dave Johnson, the Naval Sea Systems Command's program executive officer (PEO) for submarines, said "We'll be facing tough potential opponents. One only has to look at the Severodvinsk, Russia's version of a nuclear guided missile submarine (SSGN). I am so impressed with this ship that I had Carderock build a model from unclassified data".[11]

According to 60 Minutes, unnamed Pentagon officials claimed that Severodvinsk on her maiden deployment[12] "slipped into the Atlantic Ocean and for weeks evaded all of the attempts to find her" in the summer 2018.[13]

Kazan was rumoured to be active, along with five other nuclear submarines, in the northern Atlantic in spring 2020.[14] However, she may actually have been on sea trials since she was reported commissioned in May 2021.[15]

On 4 October 2021, Severodvinsk performed two test launches of Zircon missile, from surfaced and underwater position.[16] The launches were performed from White to Barents Sea and were successful.

Design

The vessel's design is said to be state-of-the-art. The Yasen-class nuclear submarines are presumed to be armed with land-attack cruise missiles, anti-ship missiles, anti-submarine missiles including the P-800 Oniks SLCM, Kalibr family SLCM or 3M51 SLCM. Kalibr-PL has several variants including the 3M54K (terminal-supersonic) and 3M54K1 (subsonic) anti-ship, 91R1 anti-submarine, and the 3M14K land-attack variant. In the future, there will be also an option to install the hypersonic 3M22 Zircon cruise missiles on upgraded 885M boats.[17] Each submarine can carry 32 Kalibr or 24 Oniks (other sources claim 40 Kalibr and 32 Oniks)[18] cruise missiles which are stored in eight (ten for 885M) vertical launchers (additional missiles may be carried in the torpedo room at the expense of torpedoes).[19] [20] [21] It will also have ten 533 mm tubes, as well as mines and anti-submarine missiles such as the RPK-7.[22]

It is the first Russian submarine class to be equipped with a spherical sonar, designated as MGK-600 Irtysh-Amfora.[23] The device (allegedly the Irtysh/Amfora sonar system) was tested on a modified Yankee-class submarine.[24] The sonar system consists of a spherical bow array, flank arrays and a towed array. Due to the large size of this spherical array, the torpedo tubes are slanted.[4] In other words, the torpedo tube outer doors are not located in the immediate bow as in the previous Akula class[25] but moved aft.[26] The hull is constructed from low-magnetic steel.[27] Unlike previous Russian submarines which have a double hull, Yasen-class submarines mostly have a single hull.[28] The Yasen class has a crew of 85 on project 885 and 64 on project 885M,[29] suggesting a high degree of automation in the submarine's different systems. The newest U.S. s, has a crew of 134 in comparison.[27]

Yasen-class submarines are the first to be equipped with a fourth-generation nuclear reactor.[30] [31] The reactor, built by Afrikantov OKBM,[32] [33] will allegedly have a 25-30-year core life and will not have to be refueled.[34] Steam turbines are supplied by Kaluga Turbine Works.[35] The inclusion of new generation KTP-6 reactor on the Yasen-M boats is thought to significantly reduce their noise level: the reactor's primary cooling loop facilitates natural circulation of water and thus doesn't require continuous operation of the main circulation pumps, which are the key noise factor on a nuclear submarine.

A VSK rescue pod is carried in the sail.

According to Admiral Foggo, the commander of the US Naval Forces Europe, the Yasen class submarines are "very quiet, which is the most important thing in submarine warfare".[13] It's claimed that Severodvinsk is far quieter than previous Russian SSNs, capable of 20 knots while running quiet, which is equal to the Seawolf class[36] and inferior only to the Virginia class (25 knots).[37] [38] Other sources claim that Severodvinsk is capable of even 28 knots in silent mode.[39]

Costs

Initial estimates regarding the cost of the first Yasen-class submarine ranged from US$1 billion to US$2 billion.[40] In 2011, it was reported that the cost of first-of-class, Severodvinsk, was 50 billion rubles (roughly US$1.6 billion)[41] while the second unit, Kazan, will cost an estimated 47 billion rubles (US$725 million, in 2019 RUB/USD exchange rate). In 2011, then Defense Minister Anatoliy Serdyukov criticized the ever increasing cost of the Borei and Yasen classes. The Minister described the massive increase in cost between the first and the second Yasen-class submarine as "incomprehensible". However, he insisted that the Russian Defence Ministry and Sevmash would resolve the issue. Officials from the United Shipbuilding Corporation replied that work done in Sevmash accounts for only 30% of the submarine's completion cost, the remaining 70% being linked to suppliers/contractors.[42]

Successor/supplement

See main article: Laika-class submarine.

Due to the high cost of each Yasen class submarine, some sources believe that a next generation of SSNs would be of smaller dimensions[43] [44] with a reduced armament/payload could be built.[45] The successor/supplement to the Yasen class was in early development by 2015[46] [47] [48] and dubbed "Husky class" by media.[49] The final design of the submarine is yet to be completed and may feature a more conventional layout with bow-mounted torpedo tubes (as opposed to the midship torpedo tubes on Yasen class) and a smaller chin-mounted sonar, i.e. the sonar will be mounted below the torpedo tubes (as opposed to a large spherical sonar on Yasen class).[50] The first submarine is expected to be delivered to the Russian Navy by 2027.[51]
