Why Independence-class carriers lacked a 5-inch battery

The Independence conversions show how hull space, emergency timing, and a carrier's real defensive needs outweighed the appeal of adding a single larger gun.

Question

Why did the Independence-class carriers lack a 5-inch gun while the smaller Casablanca class carried one?

Short answer

The cruiser-hull conversions had severe space constraints and were rushed to deliver aviation capability, while one 5-inch gun offered little surface-combat value.

Notes

The Independence class put a hangar and flight deck onto a Cleveland-class cruiser hull under an emergency program. The conversions lacked physical room for a 5-inch gun alongside the aviation facilities they had to carry. Casablanca's single gun was principally another anti-aircraft weapon rather than a serious surface battery. The comparison illustrates why conversion designs are governed by the inherited hull and by the minimum equipment needed to make aviation work.
