HALIFAX, Nova Scotia – On May 9, 2025, His Majesty’s Canadian Ship (HMCS) Margaret Brooke returned to its home port in Halifax, Nova Scotia, marking the triumphant conclusion of a groundbreaking four-month deployment under Operation PROJECTION 2025. The Harry DeWolf-class Arctic and Offshore Patrol Vessel (AOPV) achieved several historic milestones, including the first circumnavigation of South America by a Royal Canadian Navy (RCN) vessel in decades and the first recorded RCN visit to Antarctica. The deployment underscored Canada’s commitment to global naval presence, scientific research, and international cooperation.
A Journey of Firsts
Departing Halifax on January 10, 2025, HMCS Margaret Brooke embarked on a 119-day mission that covered over 20,500 nautical miles and included port visits to nine countries across South America, the Caribbean, and Antarctica. The deployment, part of Operation PROJECTION 2025, aimed to strengthen Canada’s diplomatic ties, support scientific research, and demonstrate the RCN’s operational capabilities in extreme environments.
Among the mission’s historic achievements were:
- Crossing the Antarctic Circle: HMCS Margaret Brooke became the first RCN vessel to cross the Antarctic Circle, showcasing the ship’s polar capabilities in one of the world’s most challenging environments.
- Supporting All-Canadian Antarctic Science Mission: The crew facilitated a pioneering Canadian scientific expedition in Antarctica, advancing research on climate change, oceanography, and environmental pollutants. This marked the first time an RCN vessel supported an all-Canadian science mission in the Antarctic region.
- Navigating Both Polar Regions in a Single Year: Having previously operated in the Arctic, HMCS Margaret Brooke achieved the rare feat of sailing in both the Arctic and Antarctic within a 12-month period, highlighting the versatility of the Harry DeWolf-class vessels.
- Circumnavigating South America: The deployment marked the first time in decades that an RCN ship completed a full circumnavigation of South America, reinforcing Canada’s naval presence in the Western Hemisphere.
Advancing Science and Diplomacy
A key component of the mission was the support provided to Canadian scientists studying the Antarctic region. Partnering with Polar Knowledge Canada, Natural Resources Canada, and the Marine Environmental Observation, Prediction and Response Network (MEOPAR), the crew of HMCS Margaret Brooke enabled researchers to collect critical data on ocean currents, glacial retreat, species distribution, and environmental pollutants such as plastics and chemicals. This research will enhance global understanding of climate change and its impacts on polar ecosystems.
The deployment also strengthened Canada’s international partnerships. HMCS Margaret Brooke conducted joint exercises with the Peruvian Navy, including operations with the Lupo-class frigate BAP Bolognesi and the 209/1200-class submarine BAP Angamos after a port visit to Callao, Peru. Additional stops in Valparaíso, Chile, and Punta Arenas, Chile, facilitated logistical resupply and operational rest, while a visit to the Chilean Air Force’s Presidente Frei Antarctic Base on King George Island underscored Canada’s commitment to regional cooperation.
A Testament to Crew and Capability
The success of Operation PROJECTION 2025 is a testament to the skill and dedication of HMCS Margaret Brooke’s crew of 65 sailors, led by Commander Teri Share. Operating in harsh polar conditions and navigating complex international waters, the crew demonstrated professionalism and adaptability. Rear-Admiral Josée Kurtz, Commander Maritime Forces Atlantic and Joint Task Force Atlantic, praised the crew, stating:
“Having proven themselves as professional sailors capable of operating in a wide spectrum of challenging environments, I have no doubt that they will be successful on their new mission.”
The Harry DeWolf-class AOPV, designed for operations in extreme climates, proved its mettle in the Antarctic’s icy waters. The vessel’s robust design and specialized capabilities allowed it to support scientific missions, conduct naval operations, and maintain a Canadian presence in remote regions.
A Homecoming Celebration
As HMCS Margaret Brooke sailed into Halifax Harbour, families, friends, and RCN personnel gathered to welcome the crew home. The deployment, described as a “once-in-a-career” mission, left a lasting legacy for the RCN and Canada’s global outreach. The crew’s efforts not only advanced scientific knowledge but also reinforced Canada’s role as a leader in polar operations and international maritime cooperation.
The Royal Canadian Navy celebrated the milestone on social media, noting:
“#HMCSMargaretBrooke is HOME! 🇨🇦 After a 4-month historic deployment, the crew supported Canadian research + showed the power of the Harry DeWolf-class in polar ops. Bravo Zulu! 👏”
Looking Ahead
The return of HMCS Margaret Brooke marks the end of a historic chapter but also sets the stage for future RCN operations in polar and international waters. The data collected during the Antarctic mission will contribute to global climate research, while the diplomatic ties forged during the deployment will strengthen Canada’s partnerships in the Americas and beyond.
As the RCN continues to modernize and expand its capabilities, the success of HMCS Margaret Brooke serves as a powerful reminder of the Navy’s ability to project Canada’s presence, support scientific discovery, and uphold international security in even the most remote corners of the globe.
