The Dornier Rs.II was a large biplane flying boat, designed by Claudius Dornier and built during 1914-15 on the German side of Lake Constance. Initially this aircraft was powered by three engines mounted inside the hull driving three pusher propellers via gearboxes and shafts. The later version was powered by four engines in two push-pull nacelles mounted between the wings.
