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*
*The Royal Navy sent the Arc Royal to the Fleet Review in 2010. Also present was the USS Wasp, which is an amphibious Assault ship, flightdeck not withstanding.
UPDATE: Found photos of the USS Theodore Roosevelt with the USS Essex together in 2015.
ARABIAN GULF (Aug. 28, 2015) The Wasp-class amphibious assault ship USS Essex (LHD 2) transits alongside the aircraft carrier USS Theodore Roosevelt (CVN 71). Theodore Roosevelt is deployed in the U.S. 5th Fleet area of operations supporting Operation Inherent Resolve, strike operations in Iraq and Syria as directed, maritime security operations and theater security cooperation efforts in the region.
