Widewing, they had less armor than that. No Essex flight deck was armored, unless you want to count 2" teak planks and a thin sheet of steel used under them. The hangar deck had a 2.5" plate of STS steel flooring for armor. This was the reason why a single bomb hit could utterly destroy any Essex carrier. The bomb would go through the flight deck and hit the 2.5" floor of the hangar deck, detonating almost instantly. What runs through the hangar deck? 2" diameter pipes that carry aviation fuel. So even if the hangar deck was empty, the resulting fire would eliminate flight ops entirely. The armor "belt" tapered from 4" thick down to 2.5" thick; meager defence against any torpedo. The interior was just as well protected as the hull, with 4" thick bulkheads.
As I stated in the other thread, the fleets need more AA protection and tougher guns. None of our fleet ships, save the Baltimore cruiser, were designed to be all that tough. Destroyer Escorts? They were called "tin cans" for a reason, and put up a miserable AA barrage. Dump the DEs and stick in actual destroyers. Aside from being tougher, the Fletcher-class destroyer could really pack a wallop. To compare a Rudderow-class DE to the Fletcher DD...
Rudderow DE:
Weapons:
2x 5"/38 guns (single mount)
10x20mm single
2x40mm
2x triple-rack 21" torpedo launchers
Length: 306'
Speed: 24 knots
Fletcher DD
Weapons:
5x5"/38 guns (single mount)
5x40mm twin mounts
2x 6-rack 21" torpedo launchers
Length: 376'
Speed: 35.2 knots
Then again, we could try to bag an Allen M Sumner class DD. It was bigger and much more heavily armed than the Fletcher. Simply by changing the escort ships we can increase the amount of firepower available to protect a fleet, increase the number of player-manned guns, and throw up a more effective defence. All that's left is for HT to give the 5" turrets armor so they aren't killed so quickly.
