Early carrier conversions often left internal arrangements compromised

How were fuel and munitions spaces redistributed when battlecruisers became carriers?

Not always completely; some desirable changes were omitted because they were too costly or difficult during conversion.

Some conversion problems can be reconstructed, while other details remain difficult to document. Designers sometimes recognized a needed internal change but declined it because opening and rebuilding the hull would be too expensive. The finished carriers consequently retained operational compromises.
