Ship project history: At creation of type 1936 destroyers lacks of predecessors have been considered. At the expense of more perfect hull form seaworthiness was improved, and last three ships have received clipper (Atlantic) bow, which has increased their length on 2m. Having moderated funnels height and having lightened an amidships superstructure it was possible to decrease top weight. Officially declared displacement was 1811t. Ships were equipped by Wagner boilers (70atm, 460C). Construction of Deschimag-produced turbine gear units has been improved and it has appeared quite reliable. On trials Diether von Roeder made 40.45kts. The armaments structure repeated type 1934, arrangement of antiaircraft automatic machines has changed only.
