ThyssenKrupp Marine Systems (TKMS)
German builder of non-nuclear submarines and naval systems, spun off from thyssenkrupp in 2025.
On the record
Checkpoint: Rheinmetall's decision on the GNYK acquisition and India submarine deal expected to close
The call
TKMS sits on record submarine orders and state-backed protections, but thin margins, a lost Australian bid, and negative free cash flow show the backlog still has to be built, not just booked.
ThyssenKrupp Marine Systems designs and builds submarines and naval ships mainly for NATO countries. It is hard to replace because of security clearances, government approval requirements, and years of testing that competitors cannot easily jump over, but Mitsubishi Heavy Industries just beat them for Australian work, and Rheinmetall is building a rival naval business. The company's real test is whether it can deliver its massive backlog of orders without running out of money or missing deadlines, which would prove the business can actually make good profits.
Why
01
AI pressure: None apparent. Autonomous underwater vehicles from defense-tech firms could someday supplement crewed submarines, but no such program threatens TKMS today. Could AI do the core job? Unlikely.
02
Bigger players: Rheinmetall (via NVL and GNYK acquisitions). Rheinmetall is assembling a rival marine systems house through acquisitions, but has not yet shipped a competing submarine. Could a giant copy it? No, they are blocked.
03
What protects it. German state pre-emptive ownership rights, NATO security clearances, and decades of submarine build know-how that few yards can replicate.
What would change this call
Canada finalizes or re-scopes the CPSP submarine contract terms through 2027. Shows whether TKMS converts its preferred-bidder status into a locked, executable win.
India's ~€8bn submarine deal closes or stalls by end-2026. Tests whether TKMS's backlog growth materializes into signed, executable contracts.

Key numbers
- Order backlog €20.6bn, up 55%
- FY24/25 revenue €2.2bn, EBIT margin 6.0%
- Canada CPSP program valued up to C$60bn
Named risks
- Execution risk scaling production to match 55% backlog surge amid capacity concerns.
- Negative free cash flow in H1 FY2025/26 despite revenue and EBIT growth.
- Thin 6% EBIT margins leave little buffer against program cost overruns.
- Rheinmetall consolidating German naval industry via NVL and possible GNYK deal.
- Legacy corruption-related judicial proceedings tied to 2017 Israel Dakar submarine deal.
Rivals, as read in July 2026
| Rival | Direction | Evidence |
|---|---|---|
| Rheinmetall | gaining on | Acquired NVL for ~€1.5bn and weighing GNYK bid after TKMS withdrew, Jul 2026 |
| Hanwha Ocean | losing to | Lost Canadian Patrol Submarine Project bid to TKMS, Jul 2026 |
| Mitsubishi Heavy Industries | contesting | Beat TKMS for Australian frigate contract, Aug 2025 |
| Naval Group, Navantia, Saab Kockums | gaining on | Eliminated earlier in Canada CPSP competition, leaving only Hanwha as final rival, Jul 2026 |
Questions people ask
- Is ThyssenKrupp Marine Systems (TKMS) profitable?
- Yes. In FY2024/25 (ended Sept 30, 2025), TKMS reported revenue of about €2.2 billion (up 9% YoY), adjusted EBIT of €131 million (up 53%, a 6.0% margin), and free cash flow of €784 million, though H1 FY25/26 free cash flow turned negative.
- Who owns TKMS now?
- TKMS spun off from thyssenkrupp AG and began independent trading on the Frankfurt Stock Exchange on October 20, 2025. Thyssenkrupp AG retained a 51% stake, distributing 49% to its own shareholders; the German government holds pre-emptive rights over future stake sales.
- Could AI replace TKMS's submarine business?
- No. TKMS's moat is sovereign security clearance, decades of classified hull engineering, and NATO certification, not software. It uses AI as an ingredient, signing a Cohere teaming agreement in January 2026 for Canada's submarine program, and getting DNV approval for an autonomous underwater vessel in May 2026.
- Who is TKMS's biggest competitor?
- Rheinmetall is the fastest-rising threat, having acquired NVL for about €1.5 billion and eyeing German Naval Yards Kiel after TKMS withdrew its own bid in July 2026. Hanwha Ocean lost the Canadian submarine bid to TKMS in July 2026, and Mitsubishi Heavy Industries beat TKMS for Australia's frigate deal in August 2025.
- Did TKMS win the Canadian submarine contract?
- Canada named TKMS its preferred bidder on July 6, 2026 for up to 12 Type 212CD submarines under the Canadian Patrol Submarine Project, a program valued up to C$60 billion. Contract negotiations are expected to continue through 2027 before terms are finalized.
- How big is TKMS's order backlog?
- TKMS reported a record order backlog of €20.6 billion as of its H1 FY2025/26 results (reported May 11, 2026), up 55% from €18.5 billion in June 2025, representing more than nine years of revenue at current run rates.
