Highlights:
The FD 423 is designed as far as possible and practicable according to merchant ship standards and rules given by the classification society Germanischer Lloyd.
Only in those parts, where the military service of the vessel required more specific guidance in design, the rules and regulations of the German navy were considered.
The FD 423 is manned by a military crew, the military assignment and the military service had to be considered in the design of equipment and furniture.
This class, when designed and built in the 1980-ies was the first series of naval newbuildings in Germany where due to cost restrictions the abovementioned concept of using merchant ship standards was thoroughly realized.
Highly sophisticated electronic surveillance equipment was combined in a cost-effective manner with solid ship design, resulting in an effective system of excellent seaworthiness (optimized hullform, combined with anti-roll tank stabilization system), silent propulsion (auxiliary diesel-electric) and comfortable accommodation for the operators for missions up to 30 days.
Based on the good experiences made since then, all auxiliaries for the German navy were designed and built according this cost effective mix of regulations.
