Russian shipbuilder Admiralty Shipyards has launched the first two of an additional six Project 636.3 Varshavyanka-class diesel-electric submarines (NATO reporting name: improved Kilo-class).

The ceremony took place on Friday, July 28, in St. Petersburg.

The two submarines will be named Petropavlovsk-Kamchatsky and Volkhov and will join the Russian Navy Pacific Fleet once they conclude construction.

Their six predecessors are serving with the Black Sea Fleet.

These new Varshavyanka-class submarines are being built under a contract the Russian defense ministry signed with Admiralty Shipyards and Armur Shipbuilding Plant in September 2016.

Kolpino was expected to be the Russian Navy’s final Improved Kilo-class submarines, but problems and delays in the development of the Project 677 Lada-class diesel-electric attack submarine program prompted Russia to order an additional six Project 636.3 submarines.

Under the contract from 2016, the Russian Navy is to receive the first submarine in 2019 while the other five units are expected to be delivered by 2022.

Improved Kilo-class submarines are armed with 18 torpedoes and eight surface-to-air missiles. The vessels can accommodate a crew of 52 submariners and can stay at sea for 45 days.

They displace 4,000 tonnes when submerged and reach speeds of “over 17 knots”, according the Russian Navy. The submarines are also equipped with Kalibr-cruise missiles which are also being fitted on Russian nuclear-powered Oscar-class submarines.

The ceremony on Thursday was preceded by the launch of Project 20380 corvette Gromkiy and a keel-laying ceremony for the Russian Navy’s final Yasen-M submarine Ulyanovsk.
