The famous Dutch Walrus-class submarines design dating from the 1980s and commissioned since 1992 needed to be replaced in the next decade despite their midlife modernisations. Damen Schelde Naval Shipbuilding successor of the Kon. Mij. De Schelde at Vlissingen, Netherlands and the Swedish firm Saab Kockums decided in 2015 to cooperate in designing a new submarine to be built at Vlissingen and at Karlskrona. Before the Second World War was De Schelde the most important submarine builder for the Royal Netherlands Navy also building the notorious Polish submarine Orzel. Although the new design resembles  the A26 type now used by the Royal Swedish Navy it will be a new type. One of the issues is to built submarines with a single hull either a double hull. In fact using a singe hull will be going back to the first submarine built in the Netherland, since then was chosen for a double hull. The Walrus-class consisting of the Walrus, Zeehond, Bruinvis and Dolfijn was preceded by the Zwaardvis-class.
