Armoured Flight Decks

I believe that only the Illustrious class carriers (and their successors, which do not currently have data cards) were the first to have Armored Flight decks. The Hermes, Ark Royal, Furious, Glorious, and Eagle should not have this feature.

Hello William,

The term 'armored flight deck' is a bit fluid. In Naval War, it actually notes if the deck of the carrier is the 'strength' deck with any amount of armor. Which was the case for the above carriers. It also needs to be noted that the 'armored deck' special rule has a marginal impact on hits, just reducing the penalty of bomb hits in a few instances of the Hit location table, so it might be applied a little bit more liberal than in real-world instances.

These are some of the statements that led me to include the special rule on the british carriers:
Ark Royal:
"Ark Royal featured an enclosed hangar design where the flight deck was the 'strength deck' and was strongly built with .75in (19mm) thick Ducol steel plating." -Wiki, HMS Ark Royal-

Courageous-class:
"The flight deck was 0.625 inches (15.9 mm) in thickness." (...) "Four decks were armoured with thicknesses varying from 0.75–3 inches (19–76 mm), thickest over the magazines and the steering gear. After the Battle of Jutland, 110 long tons (110 t) of extra protection was added to the deck around the magazines." -Wiki, courageous class-
This one might be a bit more tricky, but I thought it would warrant the special rule. Someone more knowledgeable about the class is welcome to chip in here as I just went of the above general comments.

HMS Hermes:
" ...and her flight deck, which was also the ship's strength deck, was 1 inch (25 mm) thick." -Wiki, HMS Hermes-

HMS Eagle:
"...The flight deck was 1 inch (25 mm) thick and served as the uppermost strength deck, or main supporting deck, of the ship." -Wiki, HMS Eagle-

Thank you for your feedback, and please let me know if I might be wrong with my assumptions.
