Designed to destroy hostile submarines and surface ships, to protect friendly naval bases, seacoast and communications, as well as to carry out reconnaissance missions. The low noise level of the submarine’s equipment and systemic utilization of advanced acoustic protection facilities provide for reduction of the noise level produced by Amur-1650 by several times than that of other submarines of this class.

The use of a highly effective sonar system and the boat’s low noisiness ensure early detection of hostile warships, including low-noise submarines. The submarine’s armament includes multipurpose torpedoes, antisubmarine rocket-assisted torpedoes, cruise missiles and mines.

The sonar system comprises highly sensitive passive transducers and electronic equipment, which make it possible to detect even low-noise submarines and surface ships at long ranges. The submarine carries a towed transducer, which is dispensed from the top vertical tail fin.

The boat’s navigation system comprises an inertial navigation subsystem which provides for the submarine safe navigation. Moreover, it generates present position data and dynamic parameters with the accuracy sufficient for the use of weapons. The commander’s periscope has two channels: optical and TV. A multipurpose periscope (optronic mast) is of a non-penetrating type. It has a thermal imager and a laser range finder. The boat’s communications facilities provide for reliable communication, both underwater and on the surface, with shore-based installations, ships and aircraft.

The radar system is equipped with passive and active antennas arranged on the non-penetrating mast. The radar system furnishes surface situation data, detects and classifies targets, as well as generates targeting and IFF data.

The submarine is propelled by a single- shaft fully electric propulsion system. The system comprises two diesel-driven AC generators with rectifiers, a propulsion electric motor with permanent magnets, and a storage battery.

The submarine, its propulsion plant, machinery and weapons systems can be controlled either from the main control room or from separate battle stations.

The submarine design takes into account the ecological requirements. Provision is made for installing the equipment used to clean bilge water from oil products, decontamination of wastewater, briquetting of rubbish and food cans, as well as crushing of garbage.

The submarine’s machinery and other systems installed in the boat feature long service life and allow the submarine to be operated for 10 years until the first factory overhaul. The total lifetime of the boat is at least 25 years.

The submarine’s crew is accommodated in comfortable cabins. The boat has a dinette, pantry, air-conditioners, air cleaners and regenerators. The Amur-class submarine can be operated in any area of the World Ocean free of continuous ice fields.
