On 12 December
2025, the third Project 677 Lada conventional submarine named after town
Velikiye Luki joined the Russian Navy. It has been 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.

Rubin Design Bureau is among the global leaders in
design of nuclear and conventional submarines and the largest marine
engineering company offering design services in Russia. More than 1000
submarines in 124 years of our work have been built to Rubin designs, including
more than 900 submarines commissioned by the Russian Navy. Totally 116
submarines designed by Rubin have been exported to 16 countries. Rubin also
develops marine robotic systems and designs the facilities for offshore oil and
gas field development. The company is a subsidiary of the state-owned United
Shipbuilding Corporation.
