Notes on classFour ships were to be built to this design but only one eventually served in the Royal Netherlands Navy. The Isaac Sweers was towed to the U.K. in May 1940 and was completed there to a different design. Two were scuttled incomplete at Rotterdam. These were raised by the Germans and one of these was completed by the Kriegsmarine as ZH-1. The fourth ship was blown up on the slip after attempts to launch her (to be towed to the U.K. just like the Isaac Sweers) failed.
