Russian Navy may finally receive Project 677M Velikiye Luki submarine before year end

On November 25, 2025, the Russian netizen Curious indicated that the Admiralty Shipyards wants to deliver the diesel-electric submarine B-587 Velikiye Luki, a Project 677M Lada-class unit, which remains in trials for now, to the Russian Navy before the New Year. The submarine has been undergoing its final sequence of trials in the Baltic, completing multiple diving phases and returning periodically to the yard for adjustments. This could finally close a program marked by several shifts in planned handover dates, initially set for 2019 and later adjusted to 2021, 2022, 2024, and now late 2025. Read full defense news at this link...

The B-587 Velikiye Luki was launched on December 23, 2022, participated in the Main Naval Parade in July 2023, and commenced sea trials on December 21, 2023, which have repeatedly continued throughout 2024 and 2025. (Picture source: Curious)
