During the war the company was almost exclusively occupied in building warships. With the exception of the battlecruisers "Repulse" and "Hood", this warship building was concentrated on destroyers. By the end of the war it had built more destroyers than any other British shipyard and set records for their building with taking seven months from keel laying to departure, six months and five and a half months. The company estimated that during the entire war period it produced a total of 205,430 tons of shipping and of machinery.
