watching the deisgn for Hiyo, you forgot angled flight deck, and ive heard airgroups over 100 are less efficient to many aircraft. Its why even modern day carriers dont go that high on plane numbers.
You need to increase your carrier capacity. I generally go for 132 by this date = 7 x 16ac squadrons (4 Jet Attack, 3 Heavy Jet Fighter) + 20 ac Special squadron.
