Naval Surface Group 4 is based out of Newport, Rhode Island and consists of 1 DD, 5 FFG and 5 FF, but their task is the Atlantic ASW mission.

Cruiser-Destroyer Group 2 is based out of Charleston, South Carolina and consists of 2 CG, 6 DDG, 7 DD, 10 FFG, 8 FF, this is slated for the Atlantic ASW/convoy escort mission.

Cruiser-Destroyer Group 8 is based out of Norfolk, Virginia and consists of 1 BB, 5 CGN, 6 CG, 13 DDG, 9 DD, 1 FFG, and 9 FF, but this is slated for carrier/convey escorts.

2nd Fleet also has a sizable submarine force:
Submarine Group 2 out of Portsmouth, New Hampshire has 7 SSBN and 2 SSN

Submarine Squadron 2 out of Groton, Conn. has 10 SSN, Submarine Development Squadron 12 is also based there and adds another 6 SSN.

Submarine Squadron 10 in New London, Conn. has 5 SSN.

Submarine Squadron 14 is based at Holy Loch, Scotland with 9 SSBN

Submarine Group 6 is based out of Charleston, South Carolina with 9 SSBN
Submarine Squadron 4 is also at Charleston with 10 SSN and 1 SS
Submarine Squadon 18 is also at Charleston with 2 SSBN

Submarine Squadron 6 and 9 are at Norfolk, Virginia with 17 SSN

Submarine Squadron 16 is at Kings bay, Georgia with 7 SSBN

The problem with the subs are that they charged with the Atlantic ASW mission and are also forward based at Holy Loch, Scotland and La Maddalena, Sardinia (6th Fleet)

Marine Support for the Caribbean is provided by the 2nd Marine Division (typically through the 4th and 6th Marine Amphibious Brigades). But the
4th MAB is assigned to reinforce Norway while the 6th MAB is slatted for duty with the Maritime Prepositioning Ships-Atlantic. 2nd Marine Division also supports the 22nd, 24th and 26th MAUs (battalion-sized) that operate in the Mediterranean with the 6th Fleet.

As you can see, the 2nd Fleet does support limited operations in the Caribbean, but its focus is on the Atlantic, especially the ASW and convoy escort missions. With the onset of warfare with the Soviet Union, I would expect the Navy to actually strip ships from the area, especially as the Soviet submarines start surging into the Atlantic. With the invasion of Mexico, I could see a handful of frigates, and Coast Guard cutters doing the main work, with the occassional cruiser and 2-3 destroyers entering the area for specific operations, and then being withdrawn back into the Atlantic.
