ST. PETERSBURG, Russia, May 31 (UPI) -- A sixth diesel-electric submarine for Russia's Black Sea fleet was launched Tuesday at a shipyard in St. Petersburg.
The Varshavyanka-class sub, named Kolpino, is an advanced version of what NATO designates as a Kilo-class submarine.
Built under the Russian Navy's Project 636.3, the submarine is between 229 and 242 feet long and has a submerged speed of as much as 25 knots. Weaponry includes torpedoes, mines and missiles.
"The submarine launch is a national event. Admiralty Shipyard is indeed the flagship of the national shipbuilding industry. Your ships are delivered on time and with proper quality."
