In the aftermath of the World Wars, many Central Powers/Axis warships were captured as War Prizes, perhaps most notably the German/Austro-Hungarian Battleships in World War 1, and the Italian/Japanese Battleships in World War 2. All of these ships were scrapped or sunk in tests after the wars, but there is very little information I can find on what was done before they were scrapped, such as how they were taken home and what modifications if any were made to bring them into service with a foreign navy. Did any at all have long service careers in their new navies?
Prinz Eugen was taken by the US after WW2 and was sunk in Operation Crossroads nuclear testing in Bikini Atholl.
The never completed German aircraft carrier was taken by the USSR along with the cruiser Lützow and sunk as a target. Also they took into their Navy a Leipzig class light cruiser Nürnberg; which was in service until 1960. Further the destroyer Z33 served in the Baltic fleet until 1961.
France took into their navy the destroyers Z31 and Z39 which served for several years.
Several other navies took Kriegsmarine ships but most were scraped or used as a target.
