MOSCOW (Sputnik) – Amid the celebration of the 320th anniversary of the Russian Navy, Korolev said:
"In late November, the construction of the series of six new Project 636.3 diesel-electric submarines for the Black Sea Fleet will be marked with raising of the Navy flag on submarine 'Kolpino'."
Korolev added that Project 1135.6 frigate Admiral Makarov, which is the third in a series of six Admiral Grigorovich-class vessels being built for the Black Sea Fleet, will join the Russian Navy in December.
The Varshavyanka-class (Project 636.3) is an improved version of Kilo-class submarines that features advanced stealth technology, extended combat range and the ability to strike land, surface and underwater targets.
The submarines are mainly intended for anti-ship and anti-submarine missions in relatively shallow waters.
