HDW Class 212A – supreme stealth

HDW Class 212A submarines can rightly be called the ultimate in German submarine technology.

This compact, air-independent non-nuclear submarine stands out for its high payloads of sensors, communication equipment, weapon control systems and weapons. Great attention has been paid to on-board efficiency and energy management. Air-independent propulsion (AIP) along with the non-magnetic construction and acoustically optimized equipment has produced a submarine that is nearly impossible to detect. The HDW fuel cell system coupled with a PERMASYN® motor enables this submarine to spend long periods submerged with low indiscretion rates. Other outstanding features include integrated weapon command and control systems, a low crew complement thanks to high levels of automation, an "undisturbed" combat information center (CIC) thanks to the double-deck configuration, and weapon tubes with water pressure launching systems.

Changing mission profiles and ongoing technological advances have led to a number of modifications in the second batch of HDW Class 212A submarines:
Integration of a communications system suitable for use in network-centric warfare scenarios
Installation of integrated German sonar and command weapon and control systems
Replacement of the flank array sonar with a superficial lateral antenna
Replacement of one periscope by an optronic mast
Integration of a diver lock-out system

HDW Class 212A submarines excel with their capability to operate from deep submerged positions far offshore or in extremely shallow waters.
