I have heard a few rumblings that the US Navy is sending an Aircraft carrier to Halifax at the end of the month. The most Detailed claim i have heard is that it is the USS Dwight D. Eisenhower, and She will anchor in Anchorage 1.
Aircraft carriers never travel alone, and the Eisenhower Carrier Strike Group Currently consists of the Ticonderoga Class Cruiser USS Normandy, and Destroyer Squadron 26; USS Stout, USS Mcfaul, USS Oscar Austin, USS Roosevelt, USS Mason, and USS Nitze. These are AEGIS and Arliegh Burke class Destroyers, though the entire squadron doesn’t always travel with the carrier.
I am unsure when the last carrier was in Halifax, but there hasen’t been one Since at least 2008*
UPDATE: Found photos of the USS Theodore Roosevelt with the USS Essex together in 2015.
