you are mis-citing Arleigh Burke's nickname. You are TECHNICALLY correct but quite misleading. The nickname was actually deeply sarcastic (at least initially).

you are mis-citing Arleigh Burke's nickname. You are TECHNICALLY correct but quite misleading. The nickname was actually deeply sarcastic (at least initially). The design speed for the Fletcher class was THIRTY FIVE knots not 31. He was limited to 31 because of I think mechanical issues was the USS SPENCE. He was initially called 31 knots as a way of calling him tardy and slow.. from arleigh burke wikipedia "He usually pushed his destroyers to just under boiler-bursting speed, but while en route to a rendezvous prior to the Battle of Cape St. George, a boiler casualty to USS Spence (DD-512) (a jammed boiler tube brush used for cleaning) limited his squadron to 31 knots, rather than the 34+ they were otherwise capable of. Thereafter, his nickname was "31-knot Burke," originally a taunt, later a popular symbol of his hard-charging nature.[2]"
