Dornier Do 214 Long-Range Flying Boat / Transport Aircraft Proposal
The Dornier Do 214 long-range flying boat only existed as a proposal during World War 2 with no prototypes constructed before the end.

The 1930s and 1940s proved an exciting time for aviation as the machine of war drove many technologies in the field. Passenger travel also gave rise to evermore powerful, larger and longer-ranged aircraft called to transport people and goods to far off places of the world. In the late 1930s, Dornier of Germany developed the P.93 project as a long-range commercial passenger flying boat to undertake the route of Lisbon-to-New York. However, in 1940, with Germany at war in Europe and elsewhere, Dornier was tasked with the job of reconstituting their P.93 design for military service and this produced the P.192 designation which proceeded under the military identifier of "Do 214".
The aircraft would incorporate a crew of twelve to fifteen personnel to man the various systems and subsystems aboard. Overall length was penciled out at 169.2 feet with a wingspan reaching 196.9 feet and a height of 46.10 feet. Empty weight was 167,550lb against a loaded weight of 320,000lb. Power would come from 8 x Daimler-Benz DB613A 24-cylinder liquid-cooled inline piston engines arranged as four paired nacelles with two props located at each leading wing edge and two props at each of the wing trailing edges. Output of each engine was an impressive 3,800 horsepower. Engineers estimated a maximum speed of 305 miles per hour with a cruising speed of 265 miles per hour. Range was out to 3,852 miles with a service ceiling of 23,000 feet attainable.
Externally, the airframe carried a boat-like hull for water-based landings and take-offs. The flight deck was fitted high over the nose for a commanding view of the action ahead. The wing mainplanes were mounted high along the sides of the fuselage and each engine nacelle streamlined for aerodynamic efficiency. The tail unit was traditional in that it carried a sole vertical fin and low-set horizontal planes. Multiple windows were set along the fuselage sides.
A mock up of the fuselage was ordered during 1941 and some work was completed on this task but the deteriorating war situation for Germany ultimately led to the cancellation of this mammoth flying boat. Fighters, interceptors, night-fighters and conventional bombers were desperately required by the Luftwaffe so there proved little need for a large flying boat. Had the project come to fruition, the aircraft would have undertaken several key roles for wartime Germany: long-range maritime patrol, general transport, anti-ship sorties, submarine resupply and the like. With the requisite trials and testing it most likely would not have been ready before 1943.
