Z-39 has surprisingly good concealment for her tier, and for a German destroyer. In fact, most of Z-39’s characteristics can be described the same way. Her 150 mm guns are some of the largest put on a destroyer in World of Warships, only matched by those available to her German compatriots Z-23 and Ernst Gaede. She has surprisingly good AA despite lacking access to Defensive AA Fire (While active, the damage per second of large caliber anti-aircraft guns is increased.), and a decent striking arm of torpedoes which reload fairly fast and travel quickly.
