Do R Superwal

The Dornier Do R Superwal was a German twin‑engine flying‑boat introduced in the early 1930s as an enlarged, more powerful version of the successful Dornier Wal. Designed by Claudius Dornier’s team, the Superwal first flew in 1932 and entered service with Deutsche Luft Hansa and several overseas airlines by 1933. Its all‑metal hull, refined hydrodynamic lines and a high‑mounted wing gave the aircraft a smooth water take‑off and increased stability in rough seas. Two 750 hp BMW Vi 12 or Pratt & Whitney Twin Wasp radials powered the type, driving three‑bladed propellers and delivering a maximum speed of about 210 km/h with a range exceeding 1 500 km. The cabin could accommodate ten to twelve passengers in comfort, while a separate cargo compartment handled mail and freight, making the Superwal a versatile workhorse for intercontinental routes across the Atlantic, the Mediterranean and the Caribbean. Although only a few dozen were built, the Superwal demonstrated the feasibility of large, long‑range amphibious transports and influenced later Dornier models such as the Do 17 and the post‑war Do 28. Its operational record helped cement Dornier’s reputation as a pioneer in metal‑hull flying‑boat design. It remains a milestone in commercial aviation.
