On August 8, 2022, the Admiralty Shipyards began the final stage of sea trials of the first production non-nuclear submarine (nNS) of Project 677D – B-586 Kronstadt.
The boats of the project are the most modern non-nuclear boats of modern Russia: one and a half hull design, the latest electronics, a powerful sonar system and a single low-noise electric motor. Plus the traditional Caliber-PL.
The project had a very difficult start, but probably everything will be fine in the 2020s.
