TKMS and Isar Aerospace Join Forces for Canada as Berlin Ponders State Entry in Defence Shake-Up

ThyssenKrupp Marine Systems teams with rocket startup Isar Aerospace, offering integrated maritime-space surveillance as Canada boosts defense spending to meet NATO targets.

ThyssenKrupp Marine Systems has struck an unlikely partnership with Munich-based rocket startup Isar Aerospace, targeting Canada’s soaring defence budget as Ottawa scrambles to meet NATO spending targets. The alliance couples submarine-building expertise with satellite launch technology — a rare combination designed to offer integrated maritime and space-based surveillance capabilities. Canada must lift military expenditure to between 2 and 3.5 percent of GDP by 2035, and the US has already paused biannual defence talks with Ottawa over its failure to meet previous commitments. For TKMS, the timing opens a clear window to pitch bundled solutions ahead of procurement cycles now gathering pace.

Isar Aerospace is preparing the second flight of its Spectrum rocket from Norway’s Andøya Spaceport, scheduled for May 2026. A successful launch would lend technological credibility to the partnership, which currently carries no immediate financial impact on TKMS’s share price. The defence sector itself is in the midst of broader consolidation, with the German government on the same day announcing a 40 percent stake in tank manufacturer KNDS via state development bank KfW, at a cost of up to €8 billion. That move, which grants Berlin equal voting rights alongside France, is seen as a blueprint for future industrial policy — and Defence Minister Boris Pistorius has explicitly floated direct state participation in TKMS.

The KNDS model draws heavily on the Airbus structure, and KNDS itself is preparing a stock market listing valued at around €19 to €20 billion, expected in June or July 2026. That IPO creates a fresh valuation benchmark for the entire German defence industry. Private investment in TKMS is becoming increasingly unlikely as the government moves toward taking a direct role; Berlin is already in negotiations with the shipyard group over the exact ownership arrangements, with talks set to continue over the coming months.

Meanwhile, TKMS’s own fundamentals remain robust. The company’s order backlog hit a record €20.6 billion, underscoring its strong market position even as the stock has pulled back from highs. Shares currently trade at €79.40, roughly 21 percent below the 52-week peak of €100.60. The relative strength index sits at 32.4, indicating oversold territory. Over the past seven days the stock has climbed 11.2 percent, recovering after a bout of profit-taking. By comparison, rival Rheinmetall slipped 1.6 percent to €1,213.80 on Wednesday as the broader DAX index also closed weaker.

The Isar Aerospace alliance is a strategic signal rather than a short-term catalyst, but it fits a pattern of sector-wide capital market activity. OHB of Bremen has started investor discussions for a potential re-IPO in June 2026, while SpaceX’s US listing is also expected that same month. The race to secure Canada’s defence dollars is just one front where TKMS is positioning itself, but the combination of a record order book, state backing, and an unconventional aerospace partnership gives it multiple levers — even as investors wait to see how the ownership puzzle in Berlin is finally resolved.
