Vindictive's limited flying platforms allowed a return to cruiser service

How could HMS Vindictive be converted back from a carrier into a cruiser?

Its flying platforms were a limited alteration around the existing cruiser superstructure, rather than a complete carrier rebuild.

Vindictive's conversion added flying arrangements around the existing superstructure without rebuilding the ship completely as a carrier. The explanation describes raised deck sections and forward and aft flying platforms, with routes around the superstructure. The ship therefore retained much of its cruiser arrangement beneath a limited set of alterations. Those changes could be reversed more readily than a complete carrier rebuild.
