The sum of the deal may be €300 million ($342 million), Afrik.com reported.
During the DSA-2014 international arms forum in Malaysia, the Malaysian navy also expressed interest for the submarine.
"Malaysian navy commander visited our display and expressed interest in our Amur-1650 submarines," a Rosoboronexport spokesman told Rossiskaya Gazeta.
The Amur-1650 diesel-electric powered submarine was developed by the Rubin design bureau. In addition to an air-independent power plant, the submarine is equipped with a regular diesel generator and a set of accumulator plants. While surfaced it is propelled by the diesel-electric power plant, and by the accumulators and the air-independent power plant while submerged. Thus, the submarine has the technical specs close to a nuclear-powered one.
The main feature of the Amur-1650 is its extreme quietness. According to experts, the new submarine outperforms the submarines of Varshavyanka (project 636) class which are now believed to be the most silent submarines in the world.
The Amur-1650 has a length of 66.8 meters and a beam of 7.1 meters. While submerged, the submarine can reach speed of 21 knots (39 kmh) at a distance of 650 miles. The submarine can submerge at a depth of 250 meters. The armament includes 18 torpedoes and 10 vertical silo-based missiles.
