How to classify the Queen Elizabeth class

Are the Queen Elizabeth-class ships escort carriers, light fleet carriers, or supercarriers?

They are best treated as light fleet or fleet carriers; their size and forty-aircraft capacity do not meet the modern supercarrier standard.

Classification depends on contemporary capability rather than a label inherited from an earlier era. Queen Elizabeth is much larger than historical escort carriers but carries far fewer aircraft than Kitty Hawk or a modern 100,000-ton nuclear supercarrier. A roughly forty-aircraft group places her near the light-fleet or fleet-carrier boundary in this scheme. The comparison also shows why displacement, propulsion, dimensions, and embarked aircraft must be considered together.
