In the mid 1942 the designs for the Midway class were approved.
The Midway class was to have an armored flight deck, unlike other American carriers. It was decided to increase armored protection throughout the ship as it was felt it needed to have protection against Japanese cruiser 8" guns. Protection against torpedoes was greatly increased.
The anti-aircraft guns were mounted on sponsons below the flight deck. The 5" L/54 dual purpose guns were mounted in single turrets.
The price for each Midway class was $90 million.
