The Dornier Do J Wal (“whale”) is a twin-engine German flying boat of the 1920s designed by Dornier Flugzeugwerke.
The Do J was designated the Do 16 by the Reich Air Ministry (RLM) under its aircraft designation system of 1933.
In the military version, a crew of two to four rode in an open cockpit near the nose of the hull.
There was one machine gun position in the bow in front of the cockpit and one or two amidships.
Beginning with Spain, military versions were delivered to Argentina, Chile and the Netherlands for use in their colonies; examples were also sent to Yugoslavia, the Soviet Union and to the end of production Italy and Germany.
The main military users, Spain and the Netherlands, manufactured their own versions under licence.
Several countries, notably Italy, Norway, Portugal, Uruguay and Germany, employed the Wal for military tasks.
