The Stěreguščij-class Bojkij corvette was in dry dock at the time of the attack on Wednesday night, where it was being repaired, the Schemi server reported on its Telegram account.
The Ukrainians hit the vessel, which in 2025 escorted ships of the Russian shadow fleet across the English Channel, in the middle of the hull, near the bridge and the structure of the tower and mast. According to the Defense Express portal, the key electronic equipment of the corvette is located in these places, namely the surveillance radar, radar for targeting missiles, navigation radars, the electronic warfare system and the artillery control station.

After the intervention, the roof of the bridge probably collapsed. Defense Express attributes this to impact and fire – the ship’s structure was made of composite materials. The portal reveals that the greatest damage to the corvette equipped with anti-ship missiles, anti-aircraft systems and torpedoes was caused by the flames. “Fires on ships are extremely destructive as flames spread through cables, ventilation ducts and inter-deck spaces,” Defense Express explained.
