I love their claim that they are "sonar proof"

The Russian Kilo Class submarine first entered into service in the early 1980s. It was designed by the Rubin Central Maritime Design Bureau, St Petersburg. Subsequent developments have led to the current production versions, the Type 877EKM and most recently, the Type 636. The submarines are constructed at the Admiralty Shipyard in St Petersburg.
24 Kilo Class submarines are in service in the Russian Navy (most of the older designs).
Kilo Class submarines have also been exported to Iran, China, India, Poland, Romania and Algeria. China has two Type 877EKMs, Iran has three Type 877EKM and India has ten Type 877EKM (Sindughosh Class). The Type 877EKM is designed for anti-submarine (ASW) and anti-surface ship (ASuW) warfare.
Submarine design
The submarine is a single-shaft vessel with a double hull. The bow planes are positioned close to the midship to improve the performance of the sonar. To reduce the submarine's acoustic signature, the flooding ports have been removed from the forebody. It also has a new gas-freeing system and the hull is covered with rubber anti-sonar protection tiles to reduce the risk of detection.
Type 877EKM has a displacement of 2,300t surfaced and 3,950t submerged. Maximum diving depth is 300m. Speed is 10kt when surfaced and 17kt when submerged. Range is 6,000 miles when snorting at 7kt and 400 miles when submerged at 3kt.
Propulsion
The Type 877EKM submarine is powered by diesel-electric propulsion with two 1,000kW diesel generators and one 5,500hp propulsion motor. These are produced by Elektrosila and Kolomensky Zavod of Russia. It also has 190hp motor for economic running and two 102hp standby propulsion systems. It has a seven-blade fixed-pitch propeller.
