Conversion of USS "Langley" into a seaplane tender allowed the Navy to fill in the remaining available treaty tonnage with a scaled-down version of the class, which became the 14,700-ton . Service experience validated the advantages of the larger hull design. USS "Ranger" proved to be unable to withstand rougher weather in the Pacific, while lack of virtually any protective features soon relegated her to a training ship. USS "Wasp"s lack of torpedo protection contributed to her loss in the Pacific theater.
