Project 971 has a double-hull design. The robust body is made of high quality alloy steel with σт = 1 GPa (10,000 kgf / cm²). To simplify the installation of equipment, the boat was designed using zonal blocks, which made it possible to transfer a significant amount of work from the cramped conditions of the sub's compartments directly to the workshop. After completion of the installation, the zonal unit is “rolled” into the hull of the boat and connected to the main cables and pipelines of the ship's systems.[6] A two-stage damping system is used: all mechanisms are placed on damped foundations, in addition, each zone unit is isolated from the body by rubber-cord pneumatic shock absorbers.[6] In addition to reducing the overall noise level of nuclear submarines, such a scheme can reduce the impact of underwater explosions on equipment and crew.[7][6] The boat has a developed vertical tail unit with a streamlined boule, in which the towed antenna is located. Also on the submarine are two reclining thrusters and retractable bow horizontal rudders with flaps. A feature of the project is the smoothly mated connection of the tail unit to the hull. This is done to reduce noise-generating hydrodynamic eddies.
Power supply is carried out by a nuclear power plant. The lead boat, K-284 Akula, is equipped with an OK-650M.01 pressurized water-cooled nuclear reactor. On later orders, the AEU has minor improvements. Some sources report that subsequent boats are equipped with OK-9VM reactors.[8] The thermal power of the reactor is 190 MW, the shaft power is 50,000 liters. with. Two auxiliary electric motors in the hinged outboard columns have a capacity of 410hp. with., there is one diesel generator ASDG-1000.
On 10 July 1993, a boat under the command of Captain 1st Rank A.A. Appolonov with a marching headquarters on board, arrived at a permanent base in Krasheninnikov Bay in Kamchatka. On August 11, the first practical shooting was performed with the PLAC with excellent marks. On 13 April 1993 the boat was named Morzh.
From October to December 1995, the tasks of the first combat service off the western shores of the United States were completed in a tough anti-submarine warfare system by the US PLC.
From May to July 1996, the tasks of the second combat service were completed.
From July to August 1997, the tasks of the third combat service were completed.
On 27 February 1998, by order of the Navy General Committee of 29 January 1998, he was rename Kuzbass, after which the combat patrol missions were successfully completed.
On 1 May 1998, after the 45th DPL was disbanded, Kuzbass was transferred to the 10th DPL of the 2nd FLPL. On 1 September 1998, he was transferred to the 16th OpEskPL KTOF.
On 1 June 2003, Kuzbass was transferred to the 16th ESCPL KTOF, then until 2005 it was used to practice combat training tasks by the 78th crew, the 622nd crew and the crew of the Guards K-295 Samara.
In 2007, Kuzbass took part in providing sea trials for the K-152 Nerpa.

In July 2008, the boat took part in the KTOF Naval Parade in the Amur Bay dedicated to the Day of the Navy. From September to December, emergency repairs took place in the city of Bolshoy Kamen.
Since 2009, the nuclear submarine has been undergoing repairs at the Zvezda shipyard in Bolshoy Kamen, which was scheduled to be completed by the end of 2013.[10] In January 2010, preparations began for loading nuclear fuel.[11] Repairs and modernization lasted until December 2015. On 18 December, the Russian Prime MinisterDmitry Medvedev and the Governor of the Primorsky Territory Vladimir Miklushevsky were shown a modernized boat.[12] On 22 December 2015, the boat was ready for a checkout to the sea with the subsequent transfer to the main basing point until the end of March 2016.[13][14][15] On 19 March 2016, the submarine was handed over to the Navy after a lengthy repair.[16]
At the beginning of September 2017, the boat successfully carried out a complex of torpedo firing from a submerged position at the ships of the imaginary enemy, the role of which was played by small anti-submarine ships of the Kamchatka group of the Pacific Fleet.[17]
As of September 2017, he is part of the 10th Submarine Division of the 16th submarine squadron of the Pacific Fleet based at Vilyuchinsk (Krasheninnikov Bay). In 2017, following the results of the championship for the challenge prize of the Commander-in-Chief of the Navy, the boat's crew won the Commander-in-Chief of the Navy prize in the individual championship of the crews of all fleets, and also received first place for performing a torpedo attack.[18]
On 15 July 2022, Kuzbass (along with Omsk and Tomsk) returned from three month deployment.[19]
The Typhoon class, Soviet designation Project 941 Akula, was a class of nuclear-powered ballistic missile submarines designed and built by the Soviet Union for the Soviet Navy. With a submerged displacement of 48,000 tonnes, the Typhoons are the largest submarines ever built, able to accommodate comfortable living facilities for the crew of 160 when submerged for months on end. The source of the NATO reporting name remains unclear, although it is often claimed to be related to the use of the word "typhoon" ("тайфун") by General Secretary Leonid Brezhnev of the Communist Party in a 1974 speech while describing a new type of nuclear ballistic missile submarine, as a reaction to the United States Navy's new Ohio-class submarine.
The Akula class, Soviet designation Project 971 Shchuka-B is a series of fourth generation nuclear-powered attack submarines (SSNs) first deployed by the Soviet Navy in 1986. There are four sub-classes or flights of Shchuka-B, consisting of the original seven Project 971 boats, commissioned between 1984 and 1990; six Project 971Is, commissioned between 1991 and 2009; one Project 971U, commissioned in 1995; and one Project 971M, commissioned in 2001. The Russians call all of the submarines Shchuka-B, regardless of modifications.
The Kilo-class submarines are a group of diesel-electric attack submarines designed by the Rubin Design Bureau in the Soviet Union in the 1970s and built originally for the Soviet Navy.
The Sierra class, Soviet designations Project 945 Barrakuda and Project 945A Kondor,, are a series of nuclear-powered attack submarines intended for the Soviet Navy and currently in service with the Russian Navy.
The Yasen class, Russian designations Project 885 Yasen and Project 885M Yasen-M, 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 a modified Yasen-M design were commissioned in 2021 and six more are under construction. Based on the Akula class and Alfa class 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).
