The Class 209/1400mod submarine is the most recent version of the HDW Class 209 “family” in a line of 63 boats contracted with 14 customer navies.
Thanks to the large number of orders, every contract profited from the latest results of Research & Development. Improvements were tested during sea trials and then incorporated without delay into the next project.
Like all its predecessors, Class 209/1400mod is a compact and reliable submarine featuring most recent technology, high combat strength, extraordinary battery payload and low signatures. Its comprehensive mission profiles include not only maritime defence and conflict prevention, but also surveillance and intelligence gathering tasks. It is also ideally suited for Special Forces operation missions.
In order to increase their indiscretion rate, Class 209 boats may be equipped with a Fuel Cell plug-in section for air-independent submarine propulsion. Such integration can be carried out during a regular midlife modernisation and leads to a considerable increase in submerged endurance.
