The AH carrier is late variant Essex class which in RL had a wooden deck that was generally painted grey to make it less visible from the air. With AH's "xxx bombs and its sunk" ship damage model its kind of irrelevant anyway.
The WW2 British fleet carriers had about 4 inches of deck armour, designed to stop a bomb of up to about 500 lbs if dropped from a jabo or dive bomber. This proved effective against Kamikaze attacks where usually the crew would recover the dead and wounded, sweep the debris off the deck, fill the dent with concrete and the carrier would be operational by the next day. Wooden deck carriers would usually need a trip back to a dockyard to repair the damage and be out of action for months.
Set against that the deck armour was heavy and this restricted the air group to 3 or 4 dozen aircraft. So with a smaller CAP a British carrier would be more likely to get hit by the Kamikaze in the first place. British carriers were designed to operate in the Med, often within range of land-based air so the armoured decks made sense there. The larger air groups of the US carriers made more sense in the Pacific theater. Both navies were well aware of the benefits to the other approach and a US-UK carrier swap was even considered at one point.
