The Varshavyanka-class (Project 636.3) is an improved version of Kilo-class submarines that features advanced stealth technology, extended combat range and the ability to strike land, surface and underwater targets.
Russia currently has 6 Project 636.3 vessels commissioned into service with the Black Sea Fleet and this package is being built for the Passific Fleet.
“The [production] cycle of a submarine is decreasing, becomes less than three years. That is why we will look forward to the new submarines and we will run up a flag of the Russian Navy when in 2019 you hand over first two submarines to us” Deputy Defense Minister Yuriy Borisov said in the keel lying ceremony.
The diesel-electric submarine has a maximum speed of 10–12 knots surfaced (18–22 km/h) and 17–25 knots submerged (31–46 km/h). A submerged displacement is around 4,000 tons. Fifty-two sailors are needed to operate the sub, which displaces 3,100 tons and can maintain continuous patrol for 45 days.
The first of the six diesel-electric submarines of project 636.3 Varshavyanka-class (improved Kilo-class) for the Pacific fleet – the Petropavlovsk-Kamchatsky – will be handed over to the Russian Navy in November 2019, Admiralty Shipyard Director General Alexander Buzakov said during the keel-laying ceremony. The last if six SSK is set to be delivered in 2022. Project 636.3 submarines are fitted with Kalibr missiles for strike at surface (anti-ship 3M-54 and 3M-541 missiles) and ground targets (cruise missiles 3M-14) and have upgraded radio-electronic equipment.
After years of inattention, Russia has embarked on an ambitious submarine-building program as part of its larger military modernization.
