The capabilities of TKMS

Surface Vessels


TKMS frigates and corvettes are designed to meet the complex requirements of today’s navies – from coastal operations to global missions. A task that is perfectly mastered by the capability profile of our MEKO® design.

Submarines


As the global market leader in non-nuclear submarines and a pioneer in the development of new surface and underwater technologies, TKMS is a reliable partner for its international customers. The HDW product brand® has always been, and still is, in a class of its own and a global symbol of technological progress.

ATLAS ELEKTRONIK


Leading electronics, sensors, hydroacoustics, and information technology form the backbone of maritime operations. From the individual component to the complete system. From unmanned missions to multi-domain operations.

Alternative fuels: A green course for road, air and maritime transport

Alternative fuels made from biomass or based on hydrogen offer promising solutions to the mobility dilemma. With the right technologies, they can be produced in a climate-neutral way - making them a major source of hope for the mobility transition.
