The Amur-class submarine (named for the Amur River), is one of the latest Russian submarine designs. It is advertised as an export version of the Lada class, a modernized version of the Kilo-class submarine with improved acoustic stealth, new combat systems, and an option for air-independent propulsion (AIP).

The new vessels are the fourth generation of the Kilo submarine family, with two models developed.

As advertised, the Amur-1650 is larger and intended for longer missions. The Amur-950 is armed with a VLS missile system capable of salvo-fire at multiple predesignated targets. Sonar signatures of these submarines are several times lower than the older Kilo-class submarines.[1] Both designs are equipped with electronic warfare armament of the newer generation created on the basis of the latest science and technology. They can be outfitted with AIP fuel cells, considerably improving submerged endurance and range. AIP capability can be added in a hull extension plug either during new build construction, or as a refit to existing boats.

The builder said these vessels can operate in all areas of the world except areas with solid ice cover, in all weather conditions, and in shallow and deep water.
