The KSS-III Canadian Patrol Submarine (KSS-III CPS) is South Korea’s latest evolution in conventional submarine technology—indigenously designed and constructed through decades of spiral development of a modern, conventional, ocean-going submarine. Over the last four decades, Hanwha Ocean has continued to evolve a proven MOTS submarine design culminating with the latest batch of the KSS submarine fleet.
Equipped with Lithium-ion batteries and an Air Independent Propulsion (AIP) system, the KSS-III CPS offers the longest submerged endurance among conventional submarines in service – exceeding 7,000 nautical miles. It is outfitted with both a state-of-the-art sonar system and acoustic tiles developed in Korea, 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.
The KSS-III is recognized as the only proven, in-service submarine platform capable of fully supporting Canada’s ‘Three Ocean Strategy’ — ensuring operational reach, surveillance, and deterrence across the Pacific, Atlantic, and Arctic Oceans.
KSS-III is not an export-only model—it is the same class of submarine actively operated by the Republic of Korea Navy in real-world conditions. This ensures Canada will benefit from a proven platform, backed by an established supply chain and validated operational and maintenance data throughout the 30+ years of in-service support (ISS).
The KSS-III is the backbone of the ROK Navy submarine force. Acquisition of the KSS-III would allow Canada to be a member of the international KSS-III User Group which consists of a growing number of nations.

We should have already been negotiating the contract with Hanwa already. But Carney lives to play politics. Next update... Carney orders 12 diesel Subs from China to uphold promise of the New World Order. Right after he's done collecting all our citizens legal firearms that is. Not even sure if that's a joke anymore.
