TKMS Partners With E3 Lithium On Canadian Submarine Offer

TKMS and E3 Lithium signed a Teaming Agreement to establish a strategic framework for cooperation in support of Canada’s future submarine capabilities under the Canadian Patrol Submarine Project (CPSP). The agreement sets the stage for collaboration on research, technology transfer and investment initiatives of mutual interest. It also aims to integrate Canadian critical minerals into the submarine supply chain, with potential benefits for both domestic industry and international export markets.

“The CPSP represents a cornerstone of Canada’s naval capability, and critical minerals are essential to the technology that powers tomorrow’s submarines,” said TKMS Chief Sales Officer Thomas Keupp. “Through this agreement with E3 Lithium, we are not only securing access to a sustainable supply of lithium but also strengthening the industrial partnership between Germany and Canada. This cooperation reflects our shared commitment to innovation, sustainability, and long-term capability development.” 

Under the agreement, TKMS and E3 Lithium, a leader in Canada’s lithium sector with the country’s largest lithium resource, will explore opportunities to leverage Canada’s lithium production for strategic applications. E3’s Clearwater Project, a direct lithium extraction development, is expected to produce up to 36,000 tonnes per year of battery-grade lithium at full capacity, supporting potential supply to German and allied industrial customers.

E3 Lithium will bring its extensive expertise in lithium resource development, extraction technology, and processing, contributing to the creation of a robust supply chain that can support both Canada’s submarine programme and potential international opportunities.

“Partnering with TKMS allows us to connect Canada’s critical minerals industry with strategic global markets while supporting a transformative national defence programme,” E3 Lithium CEO at E3 Lithium Chris Doornbos added. “This agreement is a strong step toward leveraging Canada’s lithium resources to create sustainable economic value, advance technology transfer, and strengthen industrial ties with Germany and allied nations.”

The Teaming Agreement also provides a foundation for exploring further cooperation on international projects that incorporate critical minerals into advanced technology platforms, leveraging TKMS’s global naval portfolio and E3’s leadership in the Canadian lithium sector.

Last December, TKMS signed another Teaming Agreement with Marmen, one of North America’s most respected high-precision manufacturing companies to collaborate on the production of major submarine workshare for the Royal Canadian Navy (RCN). 

Under this agreement, Marmen will manufacture selected submarine sections and complex assemblies for the 212CD submarine platform, bringing its expertise in complex, high-precision fabrication to one of the most advanced conventional submarines in service. This memorandum of understanding (MoU) highlights the intent of TKMS to include the Canadian defence industry in its industrial supply chain of submarine production by leveraging Marmen manufacturing expertise. 

TKMS Chief Sales OfficerThomas Keupp emphasises, “Through this strategic partnership with Marmen, we are expanding our industrial presence in Canada and harnessing the strengths of Québec’s manufacturing ecosystem. Marmen’s innovative approach will play a key role in supporting the 212CD programme and the needs of the RCN.” 

The inclusion of Marmen will create increased production capacity for TKMS and will be part of the knowledge transfer to Canada that will enable sovereign in service support for the life of the programme. The economic impact starts with the contract signing to build and create equipment and manufacturing capacity that will support production and create hundreds of new jobs.

The collaboration underscores the strength of Quebec’s manufacturing sector. With Trois-Rivieres recognised for its industrial excellence, advanced capabilities, and highly skilled workforce, the region continues to distinguish itself as a strategic contributor within Canada’s defence and maritime supply chain. 

Marmen is a highly respected manufacturing partner for major OEMs with indepth experience in high-precision machining, manufacturing, assembly, surface treatment, design, and engineering. With more than 900 employees and six manufacturing facilities in Canada with a production capacity of close to 1,000,000 square feet, the company undertakes strategic projects in various industries, including defence, aerospace, wind power, hydroelectric power, aviation, and others.–-shp/adj/dl (Pix:TKMS)
