South Korea Offers Submarines to Canada as Relations with Washington Deteriorate.
As Canada reassesses its strategic partnerships, South Korea is positioning itself as a reliable defense supplier capable of delivering advanced military equipment efficiently. A recent visit by a South Korean delegation to Ottawa highlights this initiative at a time when political instability in the United States is prompting several allies to diversify their sources of military procurement, as reported by the Ottawa Citizen on March 10, 2025.

A group of twelve representatives from South Korea’s defense industry and government met with Canadian officials on March 5 and 6 to promote a range of military systems, including howitzers, training aircraft, rocket launchers, and submarines. The offer includes commitments to support Canadian industry by establishing local maintenance facilities and providing full access to onboard technology, an advantage that U.S. suppliers do not always guarantee their partners.
A key element of this proposal is the KSS-III, a next-generation submarine developed by Hanwha Ocean. According to retired South Korean Admiral Steve Jeong, now vice president of the company, the platform aligns with the requirements of the Canadian Armed Forces. He emphasized that three units are already in service, and that South Korea could deliver a submarine within six years of signing a contract. With the capability to remain submerged for over three weeks without surfing and a range exceeding 7,000 nautical miles, the KSS-III is particularly suited for Arctic operations.
South Korea is becoming an increasingly prominent player in the global arms market. Its defense exports have grown significantly in recent years, particularly in Europe, where several countries are seeking to reduce their reliance on the United States. Poland has signed a contract worth over $10 billion for South Korean tanks, self-propelled howitzers, light aircraft, and missile systems, while Romania has secured a $1 billion deal for howitzers. These agreements include provisions for local production, supporting job creation and industrial cooperation.
The growth of South Korea’s defense industry is partly driven by past challenges with US suppliers. According to Jeong, South Korea previously faced rising costs and technological dependence that limited its autonomy. In response, the country developed its own defense systems, enabling it to provide NATO-compatible equipment while avoiding certain restrictions associated with U.S. exports.
This shift comes at a time when Canada is increasingly scrutinizing its dependence on U.S. technology. The F-35 fighter jets ordered for $19 billion remain under American control in terms of software and hardware updates. Similarly, the Canadian Surface Combatant (CSC) warship program, which could cost up to $80 billion, incorporates key systems controlled by the United States, potentially restricting Canada’s operational sovereignty over its own naval fleet.
Despite these concerns, the Canadian government has maintained its procurement strategy with the US, signing nearly $30 billion in military equipment contracts in 2023, including an $8 billion agreement with Boeing for surveillance aircraft and a $2.5 billion deal for drones. This approach aimed to address American criticism over Canada’s defense spending levels but has not prevented the Trump administration from increasing pressure on Ottawa.
The issue of military and economic integration with the U.S. remains a divisive topic among Canadian policymakers and defense experts. Some former high-ranking officials, such as General Rick Hillier, advocate for closer ties with Washington, while others, like retired Vice Admiral Mark Norman, warn against excessive reliance and have suggested economic countermeasures in response to U.S. pressures.
Against this backdrop, South Korea’s proposal aligns with a broader trend in which U.S. allies are exploring alternative defense suppliers. If Canada seriously considers this offer, it could mark a shift in its procurement policy, favoring partners that provide competitive and technologically accessible solutions without imposing excessive restrictions.
