May 8 (Asia Today) — South Korea’s first domestically designed 3,000-ton submarine has completed a long-distance Pacific deployment as Seoul seeks to strengthen its bid for Canada’s next-generation submarine procurement program.
The South Korean Navy said the Dosan Ahn Chang-ho departed Pearl Harbor-Hickam in Hawaii on Friday with two Canadian Navy submarine personnel aboard and is scheduled to arrive at Esquimalt Harbor in Victoria, British Columbia, in late May.
The submarine left Jinhae Naval Base on March 25 and traveled through Guam and Hawaii before heading toward Canada.
The deployment is seen as a major test of the submarine’s endurance, reliability and operational performance, as South Korean shipbuilders compete for Canada’s submarine project, estimated at about $42 billion.
The Dosan Ahn Chang-ho is expected to travel up to about 18,600 miles round trip, much of it independently. Defense officials say the mission is intended to demonstrate the submarine’s long-range capabilities, quiet operation, onboard living conditions and air-independent propulsion system.
Two Canadian Navy personnel, Maj. Britany Bourgeois and Petty Officer Jake Dixon, joined the submarine for the final leg from Hawaii to Canada.
The submarine is expected to take part in joint training with the Canadian Navy after arriving in late May. The exercises are expected to focus on anti-submarine warfare and interoperability.
Canadian officials are expected to assess whether the South Korean submarine meets key requirements for long-range patrols and operations near Arctic waters.
The Dosan Ahn Chang-ho will later participate in the U.S.-led Rim of the Pacific exercise, known as RIMPAC 2026, alongside South Korea’s next-generation Aegis destroyer Jeongjo the Great.
South Korea’s participation is expected to highlight its growing ability to operate with U.S. and allied naval forces in complex maritime environments.
Canada’s submarine procurement program calls for the acquisition of 12 submarines. South Korean shipbuilders Hanwha Ocean and HD Hyundai Heavy Industries are competing against Germany’s Thyssenkrupp Marine Systems for the contract.
Defense analysts say the Pacific deployment gives South Korea an opportunity to demonstrate proven operational capabilities directly to Canadian officials rather than relying only on written proposals or technical specifications.
The Dosan Ahn Chang-ho is the lead vessel of South Korea’s KSS-III Batch-I class. The submarine has an underwater displacement of about 3,700 tons, is 83.5 meters long and was designed and built in South Korea.
South Korean defense officials say the deployment marks a milestone for the country’s submarine program and reflects the expansion of the Navy’s operating range from coastal waters to the open ocean.
If South Korea wins the Canadian contract, it would mark the largest single defense export deal in the country’s history.
