It should be noted that on the submarines of the 636.3 project diesel generators are used, produced at OJSC Kolomensky Zavod.
The diesel-electric submarine B-237 Rostov-on-Don is the second submarine of this project built for the Black Sea fleet RF (the first - DEPL "Novorossiysk). It was officially commissioned on December 30, 2014. After the inter-naval transition, the submarine was to become a full-fledged element of the submarine fleet of the Russian Federation on the Black Sea. Now, specialists from the Kolomensky Zavod and the Admiralty Shipyards company, where the construction of a submarine for the Black Sea Fleet of the Russian Federation was involved, are involved in identifying technical problems.
