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 12 Libelle III was the third of a line of small German flying boats of the 1930s. It started with the Dornier A Libelle I and the Dornier A Libelle II, though the Do 12 was not a continuation, but an entirely new aircraft.
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 Fairey Aviation Company Fairey III was a family of British reconnaissance biplanes that enjoyed a very long production and service history in both landplane and seaplane variants. First flying on 14 September 1917, examples were still in use during the Second World War.
The Blackburn Iris was a British three-engined biplane flying boat of the 1920s. Although only five Irises were built, it was used as a long-range maritime reconnaissance aircraft by the Royal Air Force, where it equipped a squadron for four years, being used to carry out a number of notable long-distance flights. The final version of the Iris, the Iris Mark V was developed into the aircraft that replaced it in Squadron service, the Blackburn Perth.
The Beriev MBR-2 was a Soviet multi-purpose flying boat which entered service with the Soviet Navy in 1935. Out of 1,365 built, 9 were used by foreign countries including Finland and North Korea. In Soviet Union it sometimes carried the nickname of "Kорова" (cow) and "Амбар" (barn).
The Hansa-Brandenburg W.29 was a German two-seat fighter floatplane which served in the closing months of World War I with the Imperial German Navy's Naval Air Service from bases on the North Sea coast. In concept the aircraft was a monoplane version of the biplane Hansa-Brandenburg W.12, although there were many structural differences between the two.
BMW IIIa was an inline six-cylinder SOHC valvetrain, water-cooled aircraft engine, the first-ever engine produced by Bayerische Flugzeugwerke AG, who, at the time, were exclusively an aircraft engine manufacturer. Its success laid the foundation for future BMW engine designs. It is best known as the powerplant of the Fokker D.VIIF, which outperformed any allied aircraft.
The Dornier Do R Superwal was a German flying boat airliner of the 1920s.
The Dornier Komet ("Comet"), Merkur ("Mercury"), Do C, Do D, and Do T were a family of aircraft manufactured in Germany during the 1920s, originally as small airliners, but which saw military use as well. The earliest aircraft in the series were basically landplane versions of the Delphin flying boat, and although the Delphin and Komet/Merkur series diverged from each other, design changes and refinements from one family were often incorporated into the other. All variants were braced high-winged single-engine monoplanes with conventional landing gear.
The Fokker F.III was a single-engined high-winged monoplane aircraft produced in the 1920s by the Dutch aircraft manufacturer Fokker. It could carry five passengers. The aircraft was also built under licence in Germany as the Fokker-Grulich F.III.
The Savoia-Marchetti S.59 was a 1920s Italian reconnaissance/bomber flying boat designed and built by Savoia-Marchetti for the Regia Aeronautica.
The Fokker F.II was the first of a long series of commercial aircraft from the Fokker Aircraft Company, flying in 1919. In a biplane age, it presented a distinct clean, high-wing monoplane style that sold successfully across Europe and North America during the development of commercial passenger-carrying aviation.
The Aichi AB-4 was a Japanese flying boat of the 1930s. A single engined biplane, the AB-4 was intended to carry out night reconnaissance for the Imperial Japanese Navy. Six were built and accepted into service as the Experimental 6-Shi Night Reconnaissance Flying boat, three of which were converted to civil transports.
The Dietrich DP.III was a design for a 1920s German light passenger transport monoplane for six passengers designed by Richard Dietrich and was to be built by the Dietrich-Gobiet Flugzeugwerke as Kassel. Due to the financial problems of the company it is believed that the DP.III was not completed.
The Rohrbach Ro VII Robbe was an all-metal, twin engine flying boat built in Germany in the 1920s. It could be adapted to commercial or military rôles.
The Rohrbach Ro III was a twin-engined, all-metal flying boat built in Germany in the mid-1920s. A development of the Ro II, it could be configured either as an airliner or a reconnaissance aircraft. It was developed into the similar but more powerful Ro IIIa Rodra, intended only as a military reconnaissance/bomber. Four Ro IIIs were bought by Japan and two Rodras by Turkey.
The LFV V 18 Sassnitz was a German flying boat able to hold up to eight passengers. Only one is known to have flown.
The Zeppelin-Lindau Gs.I, often known post-WWI as the Dornier Gs.I after its designer Claude Dornier, was a civil flying boat developed immediate post-war from a military prototype. Its passenger cabin seated six. Only one was completed, and that was eventually scuttled to keep it out of Allied hands. Another of the military prototypes was intended to have a bigger, nine seat cabin and other refinements but the Gs.II was incomplete when discovered by Allied inspectors.
