The European Union had three major fleets.
They were the Black Sea Fleet, the Mediterranean Fleet and the North Atlantic Fleet.
These fleets were of different sizes based on the area they covered. The Black Sea Fleet was the smallest while the North Atlantic Fleet was the largest. The Black Sea Fleet had three destroyers and half a dozen corvettes.
The main military function of the Black Sea Fleet was to chock Russia's sea route in the Black Sea. Therefore, it wasn't designed for real combat and it had never been deployed for that purpose. When the situation suddenly escalated, the commanders of the ship were unsure about what to do.
"Boom!"
A destroyer that had a tonnage of over seven thousand was hacked in two by Chen Fan.
In less than ten minutes, Chen Fan had decommissioned two destroyers and four corvettes, annihilating nearly half of the Black Sea Fleet. Each of the destroyed warships was worth billions of US dollars.
