The former Curie, now assigned the designation U-14, was reconditioned and commissioned into the Austro-Hungarian Navy under the command of Korvettenkapitän Otto Zeidler on 1 June.[3][4] Zeidler remained in command until he fell ill,[11] and was replaced in mid-October by Linienschiffsleutnant Georg Ritter von Trapp.[4][Note 5] Under Zeidler's command and the first months of von Trapp's command, U-14 had no successes.[4]
