The Rumpler 6B was a German single-engine floatplane fighter with a biplane wing structure, designed and built by Rumpler Flugzeugwerke, in Berlin Johannisthal and introduced in 1916.
Born out of a requirement of the Kaiserliche Marine (Imperial Navy) for a seaplane fighter, the Rumpler 6B was, like its contemporaries the Albatros W.4 and Hansa-Brandenburg W.9, an adaptation of an existing landplane design. In Rumpler's case, the new floatplane fighter was based on the company's two-seat C.I reconnaissance aircraft. The modifications included adding a forward stagger to the wings, removal of the second (observer's) cockpit and fitting a larger rudder to offset the increased side area caused by the addition of floats. In the production aircraft, the area of the horizontal tail surfaces was also slightly reduced. The armament consisted of a fixed, forward-firing 7.92 mm (.312 in) LMG 08/15 "Spandau" machine gun mounted on port side of the engine block.
The initial version of the fighter was the 6B1. A total of 39 of these were produced, with all but one of the number having been delivered by the end of May 1917. A new version of the basic design, the 6B2, was introduced in October 1917. These aircraft retained the Mercedes D.III engine, but otherwise they were based on the C.IV, with larger dimensions and more rounded horizontal tail surfaces. In spite of the decrease in performance, 49 of this type were delivered between October 1917 and January 1918, during which time the remaining 6B1 also left the factory.
The Rumpler 6Bs were mostly employed at German seaplane bases at Ostend and Zeebrugge. Two were also sent to Kingdom of Bulgaria [1] and some to Kingdom of Romania to fight the Russians. [2] Two 6B1s were deployed the German-Turkish Naval Flying Unit (Wasserfliegerabteilung) in 1917. One pilot from this unit claimed to have shot down two aircraft that same year. [3]
The two 6B1s that were stationed at the German Naval Air Station Peynerdjik near Varna were transferred in April 1918 to the Bulgarian Navy. In 1920, they were destroyed in accordance with the clauses of the Treaty of Neuilly-sur-Seine. [4]
In February 1918, the Finnish White Army ordered one Rumpler and seven other aircraft from Germany. The aircraft was destroyed in an accident in October 1919. Another Rumpler aircraft was bought from the Germans in Tallinn in 1918 and it was used for seven years.
Hallinportti Aviation Museum has one Rumpler in storage.

The Rumpler C.VIII was a German single-engine biplane advanced trainer manufactured by Rumpler Flugzeugwerke, in Berlin Johannisthal in 1917.
The Rumpler C.IV was a German single-engine, two-seat reconnaissance biplane. It was a development of C.III with different tail surfaces and using a Mercedes D.IVa engine in place of the C.III's Benz Bz.IV. The Rumpler 6B 2 was a single-seat floatplane fighter variant with a 120 kW (160 hp) Mercedes D.III engine built for the Kaiserliche Marine.
Hansa-Brandenburg W.33 was a German two-seat, single-engined low-wing monoplane floatplane, which had been developed by Hansa und Brandenburgische Flugzeugwerke during World War I as a higher powered enlargement of the similar Hansa-Brandenburg W.29 and despite the increase in size the two types are very difficult to differentiate. Although the W.33 was built in small numbers during the war many license built versions were built after World War I.
The LFG Roland D.I was a fighter aircraft produced in Germany during World War I. It was a single-seat aircraft based originally on the Roland C.II two-seat reconnaissance type. It shared its predecessor's unusual design feature of having a deep fuselage that completely filled the interplane gap, but in comparison, the fuselage was much sleeker. While the C.II's appearance had earned the Walfisch ("Whale"), the D.I became known as the Haifisch ("Shark"). The I-struts that had been used to brace the C.II's wing were replaced by more conventional struts. Other changes to the wing included the removal of stagger from the design and the introduction of slight sweepback.
Imperial German Navy seaplanes numbers 1105 and 1106 were the only examples of a unique design produced for the navy's flying service during the First World War. They were unarmed biplanes of conventional configuration with staggered wings of unequal span. The empennage included a sizable ventral fin. Intended as training aircraft, the pilot and instructor sat in tandem, open cockpits. The undercarriage consisted of twin pontoons. The interplane strut arrangement was remarkable for its day, consisting of N-struts and V-struts without any rigging wires.
Number 1650 was the sole example of a unique seaplane design produced for the flying service of the Imperial German Navy during the First World War. From 1916 onwards, the Kaiserliche Werften produced a range of training seaplanes for the Navy, in order to free the nation's major seaplane manufacturers to produce front-line types. During the closing stages of the war, however, the Kaiserliche Werft Danzig and Kaiserliche Werft Wilhelmshaven produced a small number of front-line types as well, including this machine. Number 1650 was an armed reconnaissance seaplane equipped with radio equipment capable of transmission and reception, therefore gaining the naval CHFT classification.
Imperian German Navy seaplanes numbers 401 to 403 were the only three examples of a unique seaplane design produced for the Navy's flying service during the First World War. Production of these types commenced in April 1915 in an effort to supply the navy with a seaplane trainer of contemporary design. With the outbreak of war, the output of Germany's major seaplane manufacturers was taken up with producing front-line types, and the only trainers available were obsolete or rebuilt machines withdrawn from their original duties. Number 401 and its two siblings were delivered to the Navy in August 1915.

The Rumpler C.III was a biplane military reconnaissance aircraft built in Germany during World War I.
The Rumpler C.VII was a military reconnaissance aircraft built in Germany during World War I. It was developed from the C.IV and optimised for high-altitude missions that would allow it to operate at heights that would render it immune to interception by enemy fighters. Work on the C.VII took place after a similar attempt to develop the C.III into a high-altitude machine as the C.V failed.
The Rumpler D.I was a fighter-reconnaissance aircraft produced in Germany at the end of World War I. It was a conventional single-bay biplane with wings of unequal span braced by I-struts. It featured an open cockpit and a fixed, tailskid undercarriage. The upper wing was fitted with aerodynamically balanced ailerons and fuselage had an oval cross-section.

The Rumpler C.X, produced under the company designation Rumpler 8C 14, was a German two-seat observation aircraft. It was developed from the earlier Rumpler 8C 13 prototype by Rumpler in early 1918. The prototype had a similar wing design to the Rumpler C.VII, powered by a 260 hp (194 kW) Mercedes D.IVa engine and was later powered by a 240 hp (179 kW) Maybach Mb.IVa. The C.X had the highest top speed and service ceiling of all German C-type aircraft and an order was placed for the aircraft in August 1918, but few were built and tested before the war ended.
