*[[German aircraft carrier II]]: was a proposed conversion project for the incomplete [[French cruiser De Grasse]]. The ship was laid down in November 1938 and lay incomplete in the Arsenal de Lorient shipyard when Germany invaded France in May 1940. In 1942, Nazi Germany's Kriegsmarine decided to convert the cruiser into an auxiliary aircraft carrier with a capacity for twenty-three fighters and dive bombers. Work ceased in February 1943, however, due to concerns with the ship's design, a severe shortage of material and labor, and the threat of Allied bombing raids. In 1945, the ship was returned to France and was eventually completed as an anti-aircraft cruiser in 1956 by the [[French Navy]]<ref>{{cite book|url=https://books.google.com/books?id=bJBMBvyQ83EC|title=Conway's All the World's Fighting Ships, 1922–1946|isbn=9780870219139|last1=Gardiner|first1=Robert|year=1984|publisher=Naval Institute Press}}</ref>
