Were any German passenger liners suitable for conversion into useful light or escort carriers?
Short answerA few fast liners may have been plausible, but most required extensive work and all competed for scarce shipyard capacity.
NotesA Soryu-like design would not be especially light, and copying Graf Zeppelin's aircraft-management arrangements would reproduce its infrastructure problems. Smaller liners tended to be too slow without major machinery replacement. The reply nevertheless recalls two candidates capable of roughly 27-28 knots, an adequate rather than exceptional carrier speed. Conversion was possible in principle, though it competed for the same scarce yards and engineering effort as other warships.
