Rubin Design Bureau’s 3rd Lada submarine joins the Russian Navy

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.
