The Royal Canadian Navy has successfully test-fired a new lightweight anti-submarine torpedo, marking a key step in upgrading Canada’s naval fleet. Defence officials describe the launch as an important milestone in modernizing the country’s warships.
The test took place earlier this month at the Canadian Forces’ experimental range near Nanoose, British Columbia. HMCS Regina carried out the launch, becoming the first Canadian frigate to fire the new Mark 54 torpedo.
Strengthening Naval Capabilities
The Department of National Defence conducted the trial between February 2 and February 4. Officials say the goal was to confirm that the torpedo works safely and effectively from Canadian ships. The navy plans to upgrade combat systems on all 12 Halifax-class frigates, and the new weapon will play a central role in that effort.
Canada first moved to purchase 425 Mark 54 torpedo kits from the United States in 2019 at an estimated cost of $514 million. The U.S. State Department approved the sale later that year. The transaction moved forward after U.S. lawmakers chose not to intervene.
At the time, the Pentagon stated that the deal “will support the foreign policy and national security objectives of the United States by helping to improve the military capability of Canada,” calling Canada “an important force for ensuring political stability and economic progress and a contributor to military, peacekeeping and humanitarian operations around the world.”
Upgrading an Older Arsenal
Each kit, valued at about $1.2 million, includes advanced guidance technology and improved systems designed to counter enemy defences. The kits convert Canada’s older Cold War-era Mark 46 torpedoes into the updated Mark 54 version.
Raytheon began manufacturing the Mark 54 torpedo in 2004 in partnership with the U.S. Navy. Canada plans to equip not only its frigates but also CP-140 Aurora patrol aircraft and CH-148 Cyclone helicopters with the weapon.
First Launch from HMCS Regina
Cmdr. Darren Sleen, commanding officer of HMCS Regina, said the crew felt honoured to lead the test.
“These trials not only showcase the professionalism of our sailors, but also directly contribute to our warfighting credibility and support our relentless pursuit of personnel generation,” Sleen said.
During the trial, sailors launched the torpedo at a stationary underwater target. The exercise allowed technicians to observe how the ship’s systems detect threats, prepare the weapon, and carry out the launch. Crews collected data that will help guide future improvements.
Preparing for Operational Use
Officials say the Mark 54 provides stronger protection against underwater threats and helps keep the aging Halifax-class ships capable in modern naval operations.
“This phase of testing supports the navy’s goal of bringing the new torpedo into operational service across the fleet,” the department said. “This work will support future testing and ensure the Mark 54 torpedo is fully understood and thoroughly evaluated before it enters regular service.”
The navy will continue testing before deploying the torpedo widely. Defence leaders say the upgrade strengthens Canada’s ability to operate alongside allied forces and respond to emerging maritime challenges.
