Ship bunkerage is 16,650nm, the additional 4,200nm of fuel (968t) is additional avgas.
Hangers are in a 50mm "Box" , 196m long, with a 65mm roof, intended to exclude GP bombs and common shell. Armor deck is 40mm, to stop shell splinters and chunks that penetrate the "deck".
Weaponry is arranged with 4 twin 125mm mounts fore/aft of the island, and the remaining 8 single mounts in galleries below the flight deck fore and aft, much like CV 6's 5" guns.

I express a preference for the larger flight deck of the CV2; as Red Admiral is extremely fond of pointing out, it has good growth potential, though we don't of course know that at present.
I was not aware we were adding range to simulate avgas bunkers. That ought to be accounted for elsewhere, IMHO.

The Essex was 265m, and had larger hangers with a larger airgroup. My armored carrier has a large armored hanger to accomodate the airgroup, which made it heavy, so I made it long.

A valid point for discussion though. RA has muttered something about there should be more avgas allowance on carriers. Seemed a good way to deal with it.
Personally, I'm thinking the formula for carrier loadouts likely needs changing. Some large fixed tonnage to be a "carrier" and then the SQRT equation. As it is, smaller carriers can be more efficient, when OTL, larger carriers saw the efficiencies. Elevators, repair shops, arresting cables, catapults, ventilation...all are pretty much fixed regardless of airgroup size. Yet 10 planes is 100 tons, and 50 planes is 2500 tons...25x more for 5x more aircraft. Somethings fishy.
