Buzakov added that the submarines would be delivered to the customer within the time frame established by the contract and would join the Pacific Fleet.
The shipyard’s press office also said that the modified Project 636 submarines have higher combat effectiveness than previous projects. The submarine’s low acoustic signature, long target detection range, advanced inertial navigation system, modern automated information management system, powerful torpedo and high-speed missile armament give it priority in the field of conventional underwater shipbuilding.
The Admiralty Wharves shipyard is a leader in the construction of submarines of this type. The company provides their warranty and after-sales service.
The Project 636.3 submarine has a submerged speed of 18 knots, an immersion depth of 300 m, a cruising capacity of 45 days, a range of up to 7,500 miles. It has a crew of 52 men.
Upgraded submarines are superior to previous representatives of the project in terms of diesel generator power, full submerged speed; they have a much lower underwater noise level.
They have an optimal combination of target detection range and acoustic stealth; it is equipped with an automated information and control system and a modern inertial navigation system, which ensures the best characteristics among similar submarines.
On November 16, the Ufa project 636.3 diesel-electric submarine built by the Admiralty Wharves shipyard joined the Navy. The Pacific Fleet is expected to receive the project’s six submarines armed with Kalibr missiles by 2024.
