2022. HMCS Margaret Brooke finished warm weather trials on the ships cooling systems. HMCS Harry DeWolf conducted an Op Caribbe with the USCG.

NORTHCOM’s online magazine, “The Watch” reports,

For the first time, a Royal Canadian Navy (RCN) vessel will circumnavigate South America and visit Antarctica, as the HMCS Margaret Brooke marks the debut of Operation Projection 2025. The Harry DeWolf-class vessel left Halifax, Nova Scotia, on January 10, 2025, on the historic four-month mission.

So presumably she is in or near the Antarctic now.

“…National Research Council scientists will join the ship in Punta Arenas, Chile, for a two-week tour south of the Antarctic circle…”

The US Coast Guard would consider HMCS Margaret Brooke a light icebreaker because her 12,000 HP, same as the old Wind Class, falls below their 20,000HP lower limit for a “medium icebreaker.” As an Arctic Offshore Patrol Vessel, this is not a type the US Coast Guard has identified a requirement for.

In addition to a helicopter she reportedly is equipped with a vertical take-off and landing drone.
