The Heinkel He 70 Blitz ("lightning") was a German mail plane and fast passenger monoplane aircraft of the 1930s designed by Heinkel Flugzeugwerke, which was later used as a bomber and for aerial reconnaissance. It had a brief commercial career before it was replaced by larger types. The He 70 had set eight world speed records by the beginning of 1933.
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.
The Junkers F 13 was the world's first all-metal transport aircraft, developed in Germany at the end of World War I. It was an advanced cantilever-wing monoplane, with enclosed accommodation for four passengers, and a two seat open-air cockpit. 322 planes of the type were manufactured, which was exceptionally large number for a commercial airliner of the era, and were operated all over the globe. It accounted for over a third of air traffic in the early 1920s. It was in production for thirteen years and in commercial service for more than thirty. There were many versions including floatplanes for water landing, skis, mailplane, and different engines. Several survived in various states of repair in museums, and a replica of the type was put back in production in the 2010s;taking flight once again nearly a century after it first flew.
The Junkers Ju 90 was a 40-seat, four-engine airliner developed for and used by Deutsche Luft Hansa shortly before World War II. It was based on the rejected Ju 89 bomber. During the war, the Luftwaffe pressed them into service as military transports.
The Dornier Do 18 was a development of the Do 16 flying boat. It was developed for the Luftwaffe, but Luft Hansa received five aircraft and used these for tests between the Azores and the North American continent in 1936 and on their mail route over the South Atlantic from 1937 to 1939.
The Junkers W 34 was a German-built, single-engine, passenger and transport aircraft. Developed in the 1920s, it was taken into service in 1926. The passenger version could take a pilot and five passengers.
The Junkers G 24 was a German three-engine, all-metal low-wing monoplane passenger aircraft manufactured by Junkers from 1925. Junkers F 24 was the designation for single-engine versions of the same aircraft.
The Albatros L 73 was a German twin-engined biplane airliner of the 1920s. Of conventional configuration, it featured a streamlined, boat-like fuselage and engine nacelles. All four manufactured aircraft of that type were operated by Deutsche Luft Hansa, one of which crashed near Babekuhl on 28 May 1928.
The Albatros L 75 Ass was a German trainer biplane of the 1920s. Of conventional configuration, it seated the pilot and instructor in separate, open cockpits. The wings were single-bay, equal-span, and had a slight stagger. Production continued after Albatros was absorbed by Focke-Wulf.
The Arado V.1 was a prototype airliner, built in Germany in 1927. It was a single-engine, high-wing braced monoplane with tailwheel undercarriage. It made several long-distance flights, including carrying mail to South America, before being exhibited in Berlin in 1929, when it was bought by Deutsche Luft Hansa.
The Junkers W 33 was a German 1920s single-engine low-wing monoplane transport aircraft that followed Junkers standard practice making extensive use of corrugated aluminium alloy over an aluminium alloy tube frame, that was developed from the similar but slightly smaller Junkers F 13, and evolved into the similar W 34. One example, named Bremen was the first aircraft to complete the much more difficult east–west non-stop heavier-than-air crossing of the Atlantic.
The BFW M.20 was a German single-engine, high-wing monoplane ten-seat passenger transport aircraft, developed in the late 1920s and early 1930s. Deutsche Luft Hansa used it throughout the 1930s on a variety of routes.
The Focke-Wulf A 17 Möwe was an airliner built in Germany in the late 1920s. It was a conventional high-wing cantilever monoplane with fixed tailwheel undercarriage. The aircraft provided fully enclosed seating for up to eight passengers and had a separate, fully enclosed flight deck for the two pilots. Most examples flew with Deutsche Luft Hansa, serving until around 1936. In the early 1930s, two A 17s were used for testing the Junkers Jumo 5 diesel engine.
The Rohrbach Ro X Romar was a German long-range commercial flying-boat and the last aircraft designed and built by Rohrbach Metall Flugzeugbau GmbH.
The Heinkel HE 12 was a pontoon-equipped mail plane built in Germany in 1929, designed to be launched by catapult from a liner at sea.
Rohrbach Ro V was a seaplane manufactured by the Rohrbach Metall-Flugzeugbau company in Berlin, Germany. Only one was built, in 1927. It was delivered to Severa GmbH for comparison flights with the Dornier Do J "Superwal" and as a seaplane trainer. It was used for commercial flights in 1928 by the Deutsche Luft Hansa for the Travemünde to Oslo route.
The Junkers Ju 60 was a single engine airliner built in prototype form in Germany in the early 1930s. It was designed to meet a requirement issued by the Reichsverkehrsministerium for a German-built equivalent to the Lockheed Vega with which to equip Deutsche Luft Hansa. The result was a sleek, cantilever monoplane of conventional configuration, with wings skinned in the corrugated duralumin that had been a hallmark of Junkers designs up to this time, although this would be the last Junkers aircraft to have this feature. The main units of the tailwheel undercarriage were retractable.
The Rohrbach Ro VIII Roland was an airliner produced in Germany during the 1920s. It was a conventional strut-braced, high-wing monoplane, based loosely on the Zeppelin-Staaken E-4/20 that Adolf Rohrbach designed in 1920. It had a fully enclosed flight deck and passenger cabin, and featured fixed, tailskid undercarriage. Power was supplied by three engines, one in the nose, and two mounted in nacelles on the wings. Construction was of metal throughout.
The Heinkel HD 15 was a single-engine biplane seaplane, developed by the German aeronautical company Heinkel Flugzeugwerke in the late 1920s and remained at the prototype stage.
The Heinkel HE 6 was a single-seat floatplane developed by the German aeronautical company Heinkel Flugzeugwerke in the late 1920s.
