Why would Britain continue with the larger Implacable design?

Would Britain build another large carrier on the Ark Royal model?

The likely continuation is the 27,000-ton Implacable type, which provides more room for protection and subdivision.

Treaty limits on total carrier tonnage had influenced earlier compromises. A larger ship gives more scope for armour, subdivision, and torpedo protection. Implacable represents the design direction Britain already wanted to pursue. Continued peacetime construction could therefore follow that line without requiring a new light-carrier programme.
