Ship was rumored to have been loaded with a batch of Iranian Shaheed drones or some other ordnance which would explain the big bavovna. Whatever weapons it was carrying, they won’t be used against Ukraine.

Sorry for the X link but I pulled this from dKos and it shows the explosion:

🚨 BREAKING: Mykola Oleshchuk, Commander of the Air Force of Ukraine reports Russia’s Black Sea Fleet Large Landing Ship Novocherkassk (BDK-46) has been SUNK at the Feodosia port in Crimea as a result of this night’s strike.
