What It Is
ThyssenKrupp Marine Systems (TKMS) is a German naval defence OEM headquartered in Kiel, Germany, and one of the world's leading conventional submarine builders. TKMS, formerly HDW (Howaldtswerke-Deutsche Werft), has built over 180 submarines for 14 navies worldwide, including the Type 209 and its successor, the Type 214 — one of the most proven AIP-capable conventional submarine designs in service. TKMS is a leading competitor for India's ₹43,000 crore Project 75I programme to build 6 AIP-equipped submarines, offering the HDW Class 214 design with a proven fuel-cell Air-Independent Propulsion (AIP) system. The Class 214 has been selected by South Korea (KSS-II programme, 9 boats), Greece, Portugal, Turkey, and Israel. For P75I, TKMS has partnered with Mazagon Dock Shipbuilders (MDL) as the Indian build yard. The fuel-cell AIP system on the Class 214 is a mature, operationally proven design that eliminates the noise of diesel generators during submerged operations, extending submerged endurance to ~3 weeks without snorkelling.
Deployments & Procurement
TKMS offering HDW Class 214 (proven AIP) for India's P75I; partner MDL; competing with Naval Group Scorpene Evolved and DRDO-NPOL.
| Agency | Context | Year | Quantity / Note | Sources |
|---|---|---|---|---|
| Indian Navy / MDL (prospective) | Project 75I — HDW Class 214 with fuel-cell AIP | 2026 | ~₹43,000 cr for 6 boats; TKMS + MDL consortium | [1] |
| South Korean Navy | KSS-II programme (Type 214 variant) | 2007 | 9 boats delivered (DSME shipyard, South Korea); proven AIP operational | [1] |
| German Navy | Type 212A (fuel-cell AIP) | 2005 | 6 boats; operational fuel-cell AIP; validated TKMS AIP technology | [1] |
| Turkish Navy | Type 214 (PN1400T) | 2023 | TCG Piri Reis commissioned 2023; 6 boats total | [1] |
Open Questions
- P75I competition decision — MDL/TKMS vs MDL/Naval Group vs CSL/DRDO-NPOL
- Whether India will accept German AIP technology given EU export control sensitivities
- TKMS commitment to Indian industrial participation under P75I
- Impact of TKMS-Saab industrial partnership on P75I technology transfer
Import Dependencies
TKMS itself has no import dependencies — it is the technology source. India would import the Class 214 design and AIP system from TKMS under P75I.
| Component | Severity | Note | Pillar | Sources |

FAQ
What is TKMS offering for India's Project 75I?
TKMS is offering the HDW Class 214 conventional submarine with a proven fuel-cell Air-Independent Propulsion (AIP) system for India's Project 75I (6 submarines, ~₹43,000 crore). The Class 214 has been selected by 14 navies globally, with the fuel-cell AIP validated in German and South Korean submarines. For P75I, TKMS has partnered with Mazagon Dock Shipbuilders (MDL) as the Indian build yard.
What makes the Class 214 AIP system significant?
The Class 214 uses a proton-exchange membrane (PEM) fuel-cell AIP system that generates electricity from hydrogen and oxygen without combustion, eliminating the noise associated with diesel generators. This allows the submarine to remain submerged for up to ~3 weeks without snorkelling, dramatically reducing the risk of detection. The AIP system has been operationally validated in the German Navy (Type 212A) and South Korean Navy (KSS-II), and is considered the most mature AIP design available for export.
How does TKMS compare with Naval Group for P75I?
TKMS and Naval Group are the two leading foreign contenders for P75I. Naval Group's advantage is the operational validation of its Scorpene design through India's 6 Kalvari-class boats. TKMS's advantage is its proven fuel-cell AIP technology (more mature than Naval Group's MESMA steam-turbine AIP) and its track record of exporting to 14 navies. The Indian DRDO-NPOL indigenous design is the third contender. Contract award is expected in 2026.
