MOSCOW, August 14. /TASS/. Russia’s Navy will receive another two of the project 636.6 Varshavyanka-class submarines by the end of 2020, the Russian Defense Ministry said in a statement on Monday.
"Two project 636.6 Varshavyanka-class diesel-electric submarines named Petropavlovsk-Kanchatsky and Volkhov will be added to the Russian navy by the end of 2020, provided that their in-plant and state tests go well," the statement reads. The ministry pointed out that the two submarines had been laid down in Russia’s St. Petersburg before the Navy Day.
Project 636.6 Varshavyanka is the third-generation diesel-electric submarine with a maximum surface speed of 20 knots. These submarines are capable of submerging to a depth of 300 meters, the period of their autonomous navigation is 45 days. The crew comprises 52 men.
The Project 636 submarines are considered to be the quietest of the Russian-made submarines, this being the reason why NATO gave them the reporting name of Black Holes. These submarines are equipped with modern radar systems, communications tools, hydroacoustic stations, 533 mm torpedo launchers and the Kalibr cruise missiles.
In the past several years, Russia’s Navy has already received six Project 636.6 Varshavyanka-class submarines, which were added to the Black Sea Fleet.
In May and June 2017, a Varshavyanka-class submarine named Krasnodar, traveling in the Mediterranean Sea, fired the Kalibr cruise missiles on the ground facilities of the Islamic State terrorist Group (outlawed in Russia), located in Syria.
