Kolpino (B-271, Russian: Б-271 «Колпино») is a Project 636.3 (NATO reporting name Improved Kilo II-class) diesel-electric attack submarine of the Russian Navy. It was laid down on 30 October 2014, launched on 31 May 2016, and commissioned on 24 November 2016 for the Black Sea Fleet. Kolpino became part of a submarine brigade of six Improved Kilo II boats stationed at Novorossiysk.
Kolpino was rotated through the Mediterranean Sea Task Force between 2017 and 2019, during the Russian intervention in the Syrian civil war, where it fired Kalibr cruise missiles at Islamic State positions and command centers in Syria. It was in the Black Sea at the start of the Russian invasion of Ukraine in 2022, and has periodically gone out from its base Novorossiysk to fire missiles at targets inside Ukraine. While at port in Novorossiysk on 16 December 2025, the submarine was damaged by a Ukrainian Sub Sea Baby underwater drone.
