Project 677

IOC: Monday, October 23, 2006
Total Production: 2

Amur 950

Origin:Russia

Contractor/s: Rubin

Description: The Project 677 or Lada-class submarines have been designed to engage surface ships and submarines as well as to perform surveillance, mine laying, and special operations forces deployment missions. Long range anti-ship missiles, rockets, torpedoes and mines can be fired from the torpedo tubes at the bow. In addition, a highly efficient sonar system and reduced acoustic (noise) emissions will provide improved attack and survivability characteristics over preceding conventionally powered Russian/Soviet submarine classes.

The Project 677 is deemed as the follow-on to successful Project 877 and 636 (Kilo-class) submarines. Acoustic stealthiness has been a major concern in the design of the project 677. According to Rubin, the ship features a new efficient antisonar coating of the hull. The capability to engage multiple targets simultaneously using advanced missiles rather than torpedoes, its large endurance and cruising range, and its suitability for open ocean and shallow waters make the more lethal conventional submarines ever built.

The entire ship has been automated to facilitate operations managing them from submarine's main control room. An Air Independent Propulsion (AIP) system based on oxygen-hydrogen fuel cells is being offered for Amur-class submarines as option to achieve extended immersion endurance. The new diesel-electric propulsion system is arranged in a modular compartment which can be plugged into the basic submarine. A radio electronic equipment of a new generation, variable-speed permanent-magnet propulsion motor and storage battery with increased service life are provided to the 4th generation Russian non-nuclear submarine.

The Amur designation is applied for boats of the same class intended for the export market. The sonar complex is outfitted with a highly sensitive passive array, the area of which exceeds the area of array on the previous generation submarines by several times. The 4th generation Amur-class submarines can differ in customer requirements and operational conditions. Therefore, this means some changes in the submarine equipment and machinery such as propulsion system, sonar, etc depending on customer requests.

The Amur 950 submarine is the smallest variant of Project 677 and has been designed to operate in the littoral environment, in deep and shallow waters. In accordance with its size, its overall capabilities are slightly shrank compared to those of bigger Amur 1650. The weapon system consists of four 533mm torpedo tubes with 12 weapons between torpedoes, mines, missiles and rockets at the bow compartment. These submarines can be tailored following customer needs.
