# HDW Class 212 CD

Common Design  HDW Class 212 CD
==================================

Developed jointly by Germany and Norway, the HDW Class 212CD (Common Design) submarine is a milestone in non-nuclear submarine technology. Based on the proven 212A platform, the 212CD class features a larger hull that is characteristically diamond-shaped to reduce its signature. The propulsion system combines diesel engines and hydrogen fuel cell-based air-independent technology as power supplies, ensuring the longest dives without surfacing.
