Why light carriers carried the Korean deployment

Why did the Royal Navy send light carriers rather than large fleet carriers to Korea?

The light carriers were the ships available; the larger wartime carriers were undergoing major repairs and reconstruction for new aviation technology.

The choice reflected availability. Heavy wartime use had left the larger carriers needing repair, and their modernisation expanded as new aviation technologies appeared. HMS Victorious entered reconstruction in 1950 and did not return until 1958. The long absence shows how a jet-age rebuild could remove a major carrier from the fleet for most of a decade.
