IMO, to give enough maneuver speed;
2kts are short
3kts are the minimum
4kts are better

snip · September 22, 2014, 04:55:45 PM

The USN really does not have the combat experience to show how necessary the additional speed is. Or the engines for that matter.

The Rock Doctor · September 22, 2014, 06:07:20 PM

Can you tweak the belt length, Snip?
