Я тут сайт нашел, если вдруг повтор - звыняйтэ, куча чертежей (без теории), и надо покапаться.
The 563 destroyer escorts built during World War II were divided into six classes. Four of the six classes mounted 3"/50 guns, while the last two classes mounted the larger 5"/38 gun. The various destroyer escort classes also mounted different types of propulsion, depending primarily upon what type of engine was available due to the high demands of new construction.
The EVARTS class was the first type of destroyer escort to enter service in early 1943. These ships, commonly referred to as the short hull destroyer escort, were 290 feet long, sixteen feet shorter than the other five destroyer escort classes.
