Armoured carriers against Japanese air attack

What Japanese capabilities threatened British armoured carriers?

Japanese torpedo aircraft were the key threat, although the answer credits armoured British carriers with notable resilience in later Pacific operations.

Torpedo aircraft posed the principal danger. British Pacific Fleet carriers often kept operating after damage that would have caused more serious disruption to some U.S. carriers. Armoured decks reduced the effect of some bomb and kamikaze hits, but underwater attack still threatened propulsion, stability, and the hull below that protection. The balance of forces in 1939 differed from the mature Pacific war of 1944-45, so later carrier performance is an imperfect guide to the earlier scenario. The comparison concerns damage tolerance and force composition; the carriers were still vulnerable.
