ST. PETERSBURG. July 24 (Interfax-AVN) - The third diesel-electric submarine of modernized Project 636.3 the Admiralty Shipyards is building for the Black Sea Fleet will be launched on August 27, a source in the Russian shipbuilding industry told Interfax-AVN on Thursday.
"The Stary Oskol submarine will float out on August 27," he said.
Senior executives of the United Shipbuilding Corporation (USC), commanders of the Russian Navy and the Black Sea Fleet and Rostov-on-Don officials will attend the launch ceremony.
The lead submarine of the series, the Novorossiysk, had its keel laid in August 2010 and was launched on November 28, 2013. The second sub, the Rostov-on-Don, was launched on June 26, 2014, the construction of the third sub, the Stary Oskol, began on August 17, 2012, and the shipyard started building the fourth sub, the Krasnodar, on February 20, 2014.
In all, six submarines of the project will be built for the Black Sea Fleet within the next two years. The first submarine, the Novorossiysk, which was launched in November 2013, has practically passed sea trials.
The Admiralty Shipyards said it would lay the keels of another two submarines, the Veliky Novgorod and the Kolpino, this October.
Submarines of Project 636 have brand new navigation and automated control systems. They have an undersea speed of 20 knots, a diving limit of 300 meters, endurance of 45 days, a crew of 52 men and a displacement of 4,000. They are armed with six torpedo tubes.
Submarines of modernized Project 636 are more efficient than subs of the previous projects. They are the least noisy submarines in Russia and can detect targets on distances, which three to four times exceed the distance on which the sub can be traced by the enemy.
