The Netherlands East Indies acquired some Glenn L. Martin aircraft from 1915, and the Dutch navy ordered four Type S floatplanes which reached the motherland by ship in mid-1917. They proved both difficult to reassemble and difficult to fly. The type, built in very limited numbers, was designed by Donald Douglas. The interned German Friedrichshafen FF.33, V-2, has a similarly elaborate tailfin and rudder. The floatplanes are seen at the naval seaplane station at De Mok, on Texel Island.
