Rostov-na-Donu (B-237) (Russian: Б-237 «Ростов-на-Дону») 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 21 November 2011, launched on 26 June 2014, and commissioned on 26 December 2014, becoming part of Russia's Black Sea Fleet.
In 2015 it was deployed as part of the Mediterranean Sea Task Force during the Russian intervention in the Syrian civil war. Rostov-na-Donu fired Kalibr cruise missiles at Islamic State targets in Raqqa Governorate, Syria, on 8 December 2015, becoming the first Russian submarine to fire shots in combat since World War II. Rostov-na-Donu was later in a drydock in Sevastopol when it was heavily damaged in a Ukrainian attack on 13 September 2023. It was later restored, but was reportedly hit again and allegedly sunk on 2 August 2024. Later on 22 September 2025, it was reported that the submarine was docked in Sevastopol but out of service due to damages suffered from the strikes in 2024.
