The Casablanca-class escort carrier were 8,200 tons and could go 19 knots compared to the Essex-class carriers at 30,800 tons and 33 knots. the US made 122 of the slow, small carriers, only 24 of the bigger ones (with others in between, and then one bigger, i.e. Midway, which never saw service in the war)
