Russia’s "Black Hole" at Tests 21 August, 2019

Russian newest diesel-electric submarine Project 636.3 Petropavlovsk-Kamchatsky (Kilo-class submarine B-274) arrived at Baltic Sea for Trials. Built for Russia's Pacific Fleet, the submarine began sea tests. 

“During the shipbuilders’ sea trials, some of the submarine Petropavlovsk-Kamchatsky’s shipboard systems will be checked, including communications and hydro-acoustics,” Navy Spokesman said. Russian Deputy Defence Minister Alexei Krivoruchko earlier stated

that the Navy would get the submarine Petropavlovsk-Kamchatsky in the fourth quarter of this year.

 

The Project 636.3 is referred to the third generation of diesel-electric submarines. The submarines of this type have been designed by the Rubin Central Design Bureau. They can develop a speed of up to 20 knots, have sea endurance of 45 days and a crew of 52 men. They can dive to a depth of about 300 meters. The submarines of this class displace over 2,000 tonnes. These submarines are based on Project 877 and 636 designs. They are considered to be the most silent among Russian conventional subs. They have been dubbed the ‘Black Hole’ for their quietness. The submarine is equipped with the newest Kalibr-PL cruise missiles with an effective range of up to 2,500 kilometres (1,550 miles).

The contract for the construction of six Project 636.3 submarines for the Pacific Fleet was signed on September 7, 2016. The construction of the entire series is scheduled for completion in 2022.

There are two different Petropavlovsk-Kamchatskiy type of submarine class. K-211 Petropavlovsk-Kamchatskiy is a Project 667BDR Kalmar class (NATO reporting name: Delta III) Russian nuclear ballistic missile submarine. The submarine was built in the late 1970s and joined the Soviet fleet in 1980. She was decommissioned in 2010. Her role and those of the other boats of her class is being taken by the new Borei-class submarines. On 28 July 2017 the name Petropavlovsk-Kamchatskiy was assigned to the Kilo-class submarine B-274.
