Model Evolution:
Evolved from various civilian merchant ship designs (often C3 cargo ships) converted into escort carriers. Early designs led to specialized construction but retained the fundamental role of providing air support where fleet carriers were unavailable or insufficient.

Crucial roles in the Battle of the Atlantic (anti-submarine warfare, protecting convoys) and the Pacific Theater (air support for amphibious landings, reconnaissance, fleet defense). Famous for their role in the Battle off Samar protecting vulnerable escort carrier groups.
Key Classes
Key Classes Summary:
Long Island (AVG-1), Charger (CVE-30), Bogue (CVE-9), Casablanca (CVE-55), Commencement Bay (CVE-105). Each class had distinct origins and design features, but shared the fundamental role.
