Thyssenkrupp Marine Systems Nears Historic Indian Submarine Contract

Thyssenkrupp Marine Systems close to final approval for six AIP submarines in landmark €8 billion 'Make in India' partnership with Mazagon Dock.

Thyssenkrupp Marine Systems (TKMS) is on the verge of securing the largest export order in its corporate history. A landmark deal for the construction of six advanced submarines for the Indian Navy, valued at approximately €8 billion, has reached the final stage of governmental approval.

Final Approval Stage Underway

Official cabinet documents for the procurement are now circulating among key ministries in New Delhi for a final review. The Defense Acquisition Council, led by Minister Rajnath Singh, has already granted its preliminary approval. The proposal now awaits scrutiny from the Finance Ministry and the National Security Council before final sign-off can be given by Prime Minister Narendra Modi.

The Kiel-based naval systems specialist emerged victorious in the competitive tender against a Spanish rival. A decisive factor was the successful technical validation of its air-independent propulsion (AIP) system. This technology significantly extends the submerged endurance of conventional submarines while greatly enhancing their stealth capabilities.

"Make in India" Collaboration and Technology Transfer

The six vessels will be constructed in a strategic partnership with the state-owned Mazagon Dock Shipbuilders Limited, based in Mumbai. A critical component of the agreement involves the transfer of TKMS's proprietary AIP technology to India. This would mark the first deployment of such systems within the Indian Navy's submarine fleet.

This potential contract builds upon a longstanding industrial relationship. India previously procured HDW submarines from German shipyards in the 1980s and 1990s, a historical connection believed to have influenced the final selection.

Record Order Backlog and Global Ambitions

TKMS, which successfully listed on the Frankfurt Stock Exchange in October 2025, recently raised its revenue forecast in February to a growth range of two to five percent. The company's order book has swelled to a new record high, exceeding €18 billion.

Concurrently, the defense contractor is positioning itself for another major international program: the Canadian Patrol Submarine Project. This initiative could involve up to twelve submarines for the Royal Canadian Navy. TKMS remains the sole European bidder in the final selection phase, competing directly with a South Korean contender.

A successful contract award in India would solidify TKMS's standing as a global leader in conventional submarine manufacturing. The final decision from the Indian cabinet is anticipated within the coming weeks.
