QuoteA escort cruiser for the battleline. The 2knt advantage is felt to give enough speed to maneuver around the battleships.
IMO, to give enough maneuver speed;
2kts are short
3kts are the minimum
4kts are better
The USN really does not have the combat experience to show how necessary the additional speed is. Or the engines for that matter.
Can you tweak the belt length, Snip?
I must have just missed a tweek. Will fix

Alternative proposal. Larger, faster, more modern gun layout, thicker protected deck. Honestly, I like this one better, but its more expensive. Thoughts?

Personaly I would add 20 tons to the larger one, just so it came out to an even BP ammount and call it a day. Much more capable ship IMHO.
