I have been having great sucsess with the 88 against Merchants, Patrol Boats, and even Destroyers.
I engadged a Class C destroyer at night about 20,000 leagues of Gibralter. I opened up with my deck gun at 5000 k. I scored several good hits before the destroyer returned fire. I kept my distance more than 3000k and used all my AP shells before switching to HE.
The Destroyer tried despratley to fire back but was never able to get a good fix on me. I took one hit to the aft torpedo room, but no major damage.
The destroyer circled in the dark fireing fevorishly in the direction of my fire as I haplessly took my time and picked him apart, piece by piece.
I wonder if that is a realistic senario or just a glitch in the games Destoyer AI.
A U-boat would be a hard target to hit from 5,000m's away.
A real life scenario such as that would be disastrous. A U-boat could never hope to win a surface battle with a destroyer. Even though you have the advantage of sitting very low in the water, he will close the range so quickly that it won't really matter.
