Russian Nuclear-powered Cruise Missile Submarine Krasnoyarsk (K-571) Conducts Sea Trials
The Russian Navy Yasen-class nuclear-powered cruise missile submarine Krasnoyarsk (Okay-571) is present process trials at sea. It’s the third boat of the undertaking Yasen-M. The submarine is called after the town of Krasnoyarsk. Appreciable adjustments had been made to the preliminary Yasen design. After that, the Krasnoyarsk submarine will bear state checks the place all of its weapons will probably be checked in observe. On 30 July 2021, Krasnoyarsk was rolled out of the development corridor and subsequently launched on the water. The submarine’s future commander Captain 2nd Rank Ivan Artyushin historically smashed a bottle in opposition to the ship’s board. In February 2022, Krasnoyarsk began the mooring trials. Sea trials began on 26 June
Variations within the undertaking have appeared enough to contemplate it as a brand new upgraded model Yasen-M (Russian: ?????-?). The submarine undertaking was developed within the Malachite Design Bureau in Saint Petersburg. The Russian navy declared that the submarine will probably be improved compared to Severodvinsk, the primary of the category. In comparison with the first-of-class Severodvinsk, Kazan, Novosibirsk and Krasnoyarsk are some 40 ft (12 m) shorter, ensuing within the deletion of a sonar array from the previous’s bow. the intention was more likely to cut back development prices with out meaningfully lowering the submarine’s capabilities. Krasnoyarsk will even embrace a nuclear reactor with a newly designed cooling system.
The Yasen-class nuclear submarines are presumed to be armed with land-attack cruise missiles, anti-ship missiles, anti-submarine missiles together with the P-800 Oniks SLCM, Kalibr household SLCM or 3M51 SLCM. Kalibr-PL has a number of variants together with the 3M54K (terminal-supersonic) and 3M54K1 (subsonic) anti-ship, 91R1 anti-submarine, and the 3M14K land-attack variant. Sooner or later, there will probably be additionally an choice to put in the hypersonic 3M22 Zircon cruise missiles on upgraded 855M boats. Every submarine can carry 32 Kalibr or 24 Oniks cruise missiles that are saved in eight (ten for 855M) vertical launchers (further missiles could also be carried within the torpedo room on the expense of torpedoes). It’ll even have ten 533 mm tubes, in addition to mines and anti-submarine missiles such because the RPK-7.
Yasen-class submarines are the primary to be geared up with a fourth-generation nuclear reactor. The reactor, constructed by Afrikantov OKBM, will allegedly have a 25-30-year core life and won’t must be refueled. Steam generators are equipped by Kaluga Turbine Works. The inclusion of latest era KTP-6 reactor on the Yasen-M boats is assumed to considerably cut back their noise degree: the reactor’s main cooling loop facilitates pure circulation of water and thus doesn’t require steady operation of the principle circulation pumps, that are the important thing noise issue on a nuclear submarine. The Yasen class has a crew of 85 on undertaking 885 and 64 on undertaking 885M, suggesting a excessive diploma of automation within the submarine’s totally different programs.
