The Walrus class submarine is the only submarine class currently in operation in the Royal Netherlands Navy. They have been in use since 1990 and are all named after sea mammals. The Walrus class submarines are unusual in that instead of a cross-shaped assembly of stern diving planes and rudders, they mount four combined rudders and diving planes in an "X" configuration. This tail configuration was first tested in 1960 on the United States Navy's USS Albacore (AGSS-569), but has since been used only by the Walrus class, the Swedish Navy's Södermanland class, the Royal Australian Navy's Collins class and the German 212A class (see: type 212 submarine).
