Today, the third Project 677 Lada conventional submarine named after town Velikiye Luki has joined the Russian Navy. It was designed by Rubin Design Bureau and built at the Admiralty Shipyard (both the entities are under the United Shipbuilding Corporation).

The ship successfully underwent Shipyard's Sea Trials and State Trials in the Baltic Sea. During the trials, all ship systems including electric power system, radio electronics and torpedo-missile armament were subjected to checks. Based on the results of trials, high tactical and technical characteristics of the non-nuclear submarine were proven.

Rubin's designers supported the construction of submarine Velikiye Luki at all stages - from Project development to participation in the State Trials. At present, Rubin Design Bureau is rendering assistance in further construction of Project 677 boats.

Project 677 submarines are the most state-of-the-art and advanced Russian non-nuclear underwater ships. Low noise characteristics, means of acoustic protection and extremely powerful sonar system ensure Lada's advantage over similar foreign ships. Lada is equipped with torpedo-missile armament capable of firing at marine and shore targets.
