The Russian Navy has received a new diesel-electric submarine, Stary Oskol, strengthening its Black Sea Fleet.
Constructed at the Admiralty Shipyard in Saint Petersburg, the submarine was floated out last year.
The new submarine represents the third in a series of vessels being built under Project 636.3 as part of the navy’s fleet modernisation programme.
Under the programme, the Russian Navy will receive six submarines, which will be deployed to serve the Black Sea Fleet following the successful completion of sea trials.
Features of these submarines include advanced stealth technology, extended combat range, latest inertial navigation system and the potential to strike land, surface, and underwater targets.
With an underwater speed of 20k and a cruising range of 400m, the improved variant of the Kilo-class diesel-electric submarines can patrol for 45 days with 52 on-board submariners.
In a separate development, the navy has commissioned its new corvette at the Amur Shipyards.
The Project 20380 corvette, which is named in honour of Aldar Tsydenzhapov, is the third vessel built for the Pacific fleet, KRET reported.
Constructed in collaboration with JSC Severnaya Verf shipyard, Project 20380 Steregushchy-class corvettes are the new multirole vessels, which are intended to replace the Grisha-class corvettes.
Steregushchy-class can be deployed in coastal patrol, escort and anti-submarine warfare (ASW) operations. The vessels can engage surface ships, submarines, aircraft, and shore-based targets.
