A recent missile attack carried out by Ukraine on the Sevastopol Shipyard in Russian-annexed Crimea has resulted in significant damage to a large Russian landing ship and submarine, according to commercial satellite imagery.

The Ukrainian government announced that the two vessels, based in the port city of Sevastopol, are unlikely to be repairable following the pre-dawn attack. The Russian defense ministry confirmed the missile strike but claimed that the vessels would be fully repaired and return to service.

Black Sky, a company specializing in satellite imagery, captured overhead images of the shipyard showing the visible damage to the two vessels in dry dock. The affected ships were identified as the Minsk Project 775 Ropucha-class landing ship and the Rostov-on-Don Kilo-class submarine.

Military analysts consider this attack to be the most significant offensive against Sevastopol since the war began. The city is home to the Russian navy’s Black Sea Fleet. Russian forces annexed the Crimean peninsula in 2014 after seizing it from Ukraine.

The extent of the damage inflicted on the vessels suggests that they may be rendered permanently inoperable. However, Russia’s defense ministry remains optimistic about restoring them to full functionality. The incident marks a significant escalation of tensions between Ukraine and Russia in the region.

Further updates on the situation and any potential repercussions are yet to be disclosed.
