New Improved Kilo-Class Submarine Joined Black Sea Fleet, Last in Six-Sub Series
The solemn flag-hoisting ceremony took place on board the new submarine named Kolpino (Project 636.3 Varshavyanka, NATO classification – Improved Kilo) at the Admiralteyskie Verfi shipyard in Saint Petersburg on Thursday, November 24.
The Black Sea Fleet has already commissioned five submarines of this class: Novorossiysk, Rostov-on-Don, Stary Oskol, Krasnodar and Veliky Novgorod. The latest one was handed over to the Russian Navy less than a month ago, on October 26.
As was instructed by the defense ministry, the Rubin Central Design Bureau has upgraded key systems of the basic project 636 submarine, namely, torpedo/missile system, command information system, radar and sonar systems. General shipborne equipment faced a number of innovations as well, in order to reduce noise signature and improve crew living conditions.
Improved Kilo-class submarines were designed for anti-surface and anti-submarine warfare, defense of naval bases, sea and littoral lanes. A submarine of this class is 73 meters long, 10 meters wide, has max diving depth of 350 meters, submerged speed of 20 knots and sea endurance of 45 days. These subs are equipped with six 533-mm torpedoes, depth charges and attack missile systems Caliber.
