The Daimler G.I, originally designated Daimler R.I, was a bomber aircraft designed and built in Germany from early in 1915. [1]
When the Daimler works entered the aircraft manufacture business they ordered a Union G.I from Union Flugzeugbau, which flew but disintegrated shortly before landing during a test-flight, due to severe engine vibrations. Daimler commenced to re-design the Union G.I, resulting in the Daimler R.I. [1]
Development of the Daimler bombers was accelerated by the use of former Union designers Baurat Rittberger and Ing. Karl Schopper, who proceeded to strengthen the structure and replace the Union G.Is troublesome inverted engines with upright Mercedes D.IIIs. Assembly of the R.Is and R.IIs took place at Sindelfingen, but most of the R.I and R.ll parts were built by the Stuttgart firm of Schiedmayer and taken to Sindelfingen for assembly. [1]
Flight trials commenced late in 1915 with relatively few engine problems but the structure had to be strengthened several times and three wing arrangements were also tested between 1915 and 1917. A second R.I was built with a larger tail unit to improve directional control. [1] Daimler also built six almost identical improved R.II aircraft in 1916, two of which flew, the remaining four being crated and stored. [1]
The airframe of the R.I and R.II was typical of large German aircraft of the time, with a wooden fuselage and metal wings covered with fabric. The fuselage housed the crew in a gunners cockpit in the nose, cockpit amidships and a gunner's cockpit aft of the wings. The tail-unit consisted of a tailplane which supported a fin and rudder as well as two additional rudders at approximately half span. The undercarriage comprised a twin nose-wheel assembly, four main-wheels spread between the engine nacelles on the lower wings and a tail-skid. Engines were initially in tandem push-pull nacelles mounted directly on the lower wing, changing to streamlined nacelles mounted on struts mid gap on the R.II. [1]
Poor performance and competition from similar aircraft precluded production, but at least one R.I and two R.IIs were accepted by Idflieg and test flown until the middle of 1917. [1]

The AEG G.II was a German biplane bomber aircraft of World War I developed from the AEG G.I, with more powerful engines. The G.II was typically armed with three 7.92 mm (.312 in) machine guns and 200 kg (440 lb) of bombs. The bomber suffered stability problems, and many G.IIs were fitted with additional vertical tail surfaces on each side of the fin and rudder to improve flight handling characteristics.

The Focke-Wulf Fw 191 was a prototype German bomber of World War II, as the Focke-Wulf firm's entry for the Bomber B advanced medium bomber design competition. Two versions were intended to be produced, a twin-engine version using the Junkers Jumo 222 engine and a four-engine variant which was to have used the smaller Daimler-Benz DB 605 engine. The project was eventually abandoned due to technical difficulties with the engines.
The Zeppelin-Staaken R.VI was a four-engined German biplane strategic bomber of World War I, and the only Riesenflugzeug design built in any quantity.
The Friedrichshafen G.I was a prototype heavy bomber aircraft that was built in Germany by Flugzeugbau Friedrichshafen in 1915. It was Karl Gehlen's first design for the company, and although it was not produced in quantity, it provided the foundation for the later, highly successful bombers culminating in the G.III.
The Savoia-Marchetti SM.88, was an Italian twin-engined, three-seat, heavy fighter prototype of World War II, featuring a twin-boom structure, and powered by German Daimler-Benz DB 601 engines.
The Savoia-Marchetti SM.91 was a two-seat, twin-engined, Italian heavy fighter prototype, designed to compete in a 1942 revision to a long-range fighter-bomber contract offered by the Regia Aeronautica to Italian aircraft companies in 1938. The original 1938 specification yielded the Savoia-Marchetti SM.88, which the SM.91 was largely based on.
