Project history

Former Dutch destroyer Gerard Callenburg of Isaak Sweers class. She was scuttled in Rotterdam incomplete 14.5.1940, salvaged by Germans 17.7.1940, renamed ZH1 and 11.10.1940 towed off to Blohm & Voss, Hamburg, for repair and completion. Sister-ships ZH2 (ex-Tjerk Hiddes) and ZH3 (ex-Van Galen) were never completed.

British-type machinery consisted from Yarrow boilers and Parsons turbines has been retained for comparison with machinery of modern German destroyers. On trials ZH1 made 37.5kts at 53000hp.

Main gun director turn angle sector 135° on each side that did not allow to control fire on stern relative bearings.
