As a result of stability problems, the range of the ships had to be restricted by navy regulations, allowing them to use only half of the fuel carried, to prevent the ships from becoming too light. The bow proved to be of faulty design, resulting in the ships being rather wet in heavy seas. This was fixed by rebuilding all four ship of the class before 1939.
Due to stability issues, the ships' range was restricted by naval regulations, limiting them to using only half of their fuel capacity to prevent excessive weight loss. The bow design proved faulty, causing the ships to be prone to water ingress in rough seas. This issue was resolved by rebuilding all four vessels of the class before 1939.
