The S1000, a 1,000-ton diesel submarine, is a joint project of Russian submarine-builder Rubin and Italian Fincantieri launched in 2004.

The sub is designed for anti-submarine and anti-ship warfare, reconnaissance missions, and transportation of up to 12 troops. It is 56.2 meters long, has a top speed of 14 knots and is equipped with a new fuel cell-powered Air Independent Propulsion (AIP) system developed by the Italian firm.

Designed primarily for exports to third countries, the new submarine will feature an impressive array of weaponry, including Italian heavyweight, wire-guided Black Shark torpedoes and the Russian Club-S cruise missile system capable of hitting underwater, surface and land targets.

The 20th International Naval Defense and Maritime Exhibition and Conference is being held at the Paris-Le-Bourget exhibition center on October 23-27.
