Submariners conducted torpedo firings during a transit to a combat training area after conducting preparatory exercises. All torpedoes were subsequently recovered by a torpedo recovery boat from the water. Torpedo firings are a mandatory element of submariners’ combat training and are conducted in accordance with the approved plan.

Project 636.3

The Project 636.3 submarines, which are 74 meters long and displace more than 3,900 tons, are known for their strong hull and operational depth of up to 240 meters, with a maximum depth of 300 meters.

They have a diesel-electric propulsion system that includes two 1,000 kW diesel generators, a 5,500-6,800 shp propulsion motor, and a fixed-pitch 6 or 7-bladed propeller.

These submarines have an operational range of up to 7,500 miles and are armed with Kalibr-PL cruise missiles that can be launched from torpedo tubes from the sub’s submerged position.

They are considered among the world’s quietest submarine cruisers and can accelerate to 20 knots with a sea endurance of 45 days and a crew of 52 men.

Several Project 636.3 submarines, including the Veliky Novgorod, the Kolpino, and the Rostov-on-Don, have been used to deliver strikes with Kalibr-PL cruise missiles against terrorist targets in Syria.
