This RESTRICTED German naval recognition sheet comes from the Naval Air Combat Information Officers School located in Quonset Point, Rhode Island. This page comes from a set that was used to identify and recognize German warship light cruisers, heavy cruisers, battleships and destroyers. This sheet specifically shows how to identify characteristics of a German DD.

Combatants in war have consistently bombed and shot at their own ships and those of their allies, intelligence sources such as this were created to differ friend from foe. While the objective of all seagoing personnel should be to recognize important ships or types at a glance, familiarity with the details of naval design illustrated in the following pages may prove of value to the student of ship identification. Determination of a ship's type must constitute a primary step in identification in combat areas. Since accurate estimation of a ship's size is extremely difficult at sea, an observer may have occasion to resort to certain rules of thumb to differentiate various types of fighting ships.
