Hanwha Ocean and PCL Construction Sign Teaming Agreement
Press Release + Noah Note
Companies strengthen their strategic partnership, combining proven technology with strong domestic execution capabilities, to delivery long-term infrastructure in support of Canadian Patrol Submarine Project
April 7, 2026, Ottawa, Ontario
Hanwha Ocean and PCL Construction have signed a Teaming Agreement to further advance collaboration on submarine maintenance, repair, and overhaul (MRO) infrastructure as part of the Canadian Patrol Submarine Project (CPSP). The agreement builds on a Memorandum of Understanding signed last year by the two companies, and reflects a shared interest in developing a more structured and integrated approach to collaboration in Canada.
At the centre of the partnership is the opportunity to support the development of submarine MRO infrastructure on both coasts, including facilities in Esquimalt, British Columbia and Halifax, Nova Scotia. Such infrastructure is widely seen as a key component in enabling Canada to sustain and operate its submarine fleet over the long term.
PCL, one of Canada’s leading construction firms, brings extensive experience in delivering large-scale infrastructure projects across the country, including for the Government of Canada, the Department of National Defence and the Canadian Armed Forces, along with a well-established domestic supply chain and skilled workforce. PCLs involvement highlights the role of Canadian industry in any future infrastructure development related to CPSP.
Hanwha Ocean contributes experience in submarine design, construction, and sustainment, based on decades of involvement in naval programs. The company’s background in integrating complex systems and supporting lifecycle operations provides a foundation for potential collaboration in submarine infrastructure.
The two companies are aligning their capabilities across design, engineering, construction, and supply chain coordination to support Canada’s evolving submarine infrastructure requirements. The collaboration reflects a broader trend toward partnerships that combine international technical experience with domestic industrial capacity. Such approaches are increasingly seen as a way to support long-term capability development while ensuring meaningful participation from local industry.

About the KSS-III Canadian Patrol Submarine (www.KSS-III.ca)
Hanwha Ocean’s KSS-III is a proven, in-service, in-active production submarine that fully meets and exceeds all requirements for the Canadian Patrol Submarine Project (CPSP). These include superior underwater surveillance capability and deployability in the Arctic with extended range and endurance that will provide stealth, persistence and lethality to ensure that Canada can detect, track, deter and, if necessary, defeat adversaries in all 3 of its oceans.
Equipped with Lithium-ion batteries and an Air Independent Propulsion (AIP) system, the KSS-III offers the longest submerged endurance among any conventional submarine – exceeding 7,000 nautical miles. It is outfitted with both a state-of-the-art sonar system and acoustic tiles, offering outstanding target detection capability and advanced stealth performance. The platform is fully optimized for Anti-Submarine Warfare, Anti-Surface Warfare, Intelligence, Surveillance and Reconnaissance (ISR), Minelaying, and Special Operations Forces (SOF) support.
Importantly, Hanwha Ocean has the fastest delivery schedule, able to deliver four KSS-III submarines to fully replace Canada’s current Victoria Class fleet before 2035 if on contract in 2026. Earlier retirement of the Victoria Class fleet will result in estimated savings of approximately $1 Billion on maintenance and support costs. The additional 8 submarines will be delivered at a rate of one per year, meaning the entire fleet of 12 submarines will be delivered to Canada by 2043. No other option can come anywhere close to this delivery schedule.

Noah Note: Another upgrade to a Teaming Agreement for Hanwha. The interesting thing to me is the mentions of Esquimalt and Halifax for potential MRO facilities, something I don't believe Hanwha has done before. Interesting…
