Serving officers and World War II veterans attended the ceremony at the Red Banner Submarine Training College last week.
The college was founded on March 27, 1906, which has been adopted as the official birthday of the submarine fleet.
Founded in Liepaya (Latvia), the college changed location several times -- from Tallinn (Estonia) in 1914 to Petrograd in 1915.
It finally established its home at Bolshoy Prospect, Vasilyevsky Island, in 1944. The college numbers 40 Heroes of the Soviet Union among its graduates.
Their feats of courage have become legendary: Captain Kolyshkin alone destroyed 30 enemy vessels; Captain Gadzhiyev not only sank his target which was guarded by a special convoy, but succeeded in torpedoing three ships in the convoy as well.
It is thought the first submarine appeared in Russia back in 1718.
Its inventor, Yefim Nikonov, a carpenter from the village of Pokrovskoye, near Moscow, dubbed his creation "a secret vessel" designed to "shell enemy ships on calm seas."
According to the college's museum archives, Peter the Great authorized the wooden submarine to be produced under royal license on January 31, 1720. (SPP)
