Re(3): The Navy is resurrecting a fleet to protect the East Coast and North Atlantic from Russia Posted on 5/6/2018 at 12:36:41 by Bill Crawford, (14)
Being in the Atlantic Fleet for all of my at-sea time in the Navy,
I seem to recall (maybe incorrectly) always being assigned to either the Sixth Fleet or the Second Fleet (except for the time I was the skipper of the Sagamore (ATA 208), when I was assigned to the Commandant of the Fifth Naval District).
In any event, the below-linked article describes the activities of the Second Fleet, over the years. Ditto, below, for the Fleet Forces, Atlantic. (https://en.wikipedia.org/wiki/United_States_Fleet_Forces_Command)
