Upon returning to active service, the ship spent several months training officer cadets in the Baltic before serving as artillery support for the retreating German Army on the Eastern Front. After the German collapse in May 1945, she was surrendered to the British Royal Navy before being transferred to the US Navy as a war prize. After examining the ship in the United States, the US Navy assigned the cruiser to the Operation Crossroads nuclear tests at Bikini Atoll. Having survived the atomic blasts, "Prinz Eugen" was towed to Kwajalein Atoll, where she ultimately capsized and sank in December 1946. The wreck remains partially visible above the water approximately two miles northwest of Bucholz Army Airfield, on the edge of Enubuj. One of her screw propellers was salvaged and is on display at the Laboe Naval Memorial in Germany.
