Awww... the Fletcher Class Destroyers!!
I literally started playing World of Warships for the Fletcher and Gearing, however all the US destroyers are awesome to playing with in my opinion. Getting there, I'm at level 9 at the moment. I can paint my ships all kinds of camouflage now.
The Fletcher was just an awesome destroyer at the time and it really was a "tin-can" that packed a punch. It was fast, it had radar, it could throw a wall of steal in the air.
The Gearing class added the two 5 inch gun turrets and the Allen M. Sumner-class destroyers extended the mid-ship by like 14 feet. My father served on an Allen M. Sumner-class destroyer when he was in the Navy. Those old ships really rocked in the water and your were definitely getting wet. Water was constantly flowing down the decks and p-ways.
The old destroyers was literally the reason why I chose a Guided-Missile Frigate when I was in the Navy, I wanted a small boy. They are about the same size, same size crew and packed a pretty good punch. The Arleigh Burke class destroyer are awesome, but they are really a platform for the Aegis radar system and they are a much bigger ship. You get to know everyone on a Frigate, it's a family. Plus, we were faster than the Destroyers and a lot more maneuverable.
