Applying Age of Sail rates to modern aircraft carriers

How might Age of Sail ship rates be adapted to classify modern aircraft carriers?

US nuclear supercarriers define the first rate; British, French, and emerging large Chinese carriers fit the second; most existing Chinese and Indian carriers the third; and smaller Japanese, Italian, or amphibious aviation ships the fourth.

The answer uses the American nuclear carrier as the benchmark first rate because it combines the largest air group with exceptional endurance and support capacity. Successively smaller or conventionally powered carriers fall into lower rates, while aviation-capable amphibious ships sit near the boundary. The exercise exposes how widely ships called carriers differ in actual combat and sustaining power.
