No less than eleven manufacturers produced triplane, single seat fighters in the summer of 1917, including Albatros, whose Dr I simply married a new triplane wing to an otherwise standard DV airframe.
When triplanes seemed to hold the most promise as fighters a number of designs were put forward. This Albalros DrI was built in 1917 - and as can be clearly seen it was essentially an Albatros DV with an extra wing added.
Second to last Roland fighter was the experimental Type D.XVI. (160 h.p. eleven-cylinder Siemens-Halske Sh III engine.)
A Siemens-Halske Sh III engine distinguished the second of the two D XVI fighter prototypes.
Despite carrying the Zeppelin-Lindau name, the division headed by Claudius Dornier the D.I, first flown on 4 June 1918, was designed by Adolph Rohrbach, head of the Zeppelin-Staaken division. Like its few Zeppelin-Lindau forebears, this latest single seat, biplane fighter used light alloy as its primary structural material. Externally, the 185hp BMW IIIa powered D.I was an exceptionally clean design, with fully cantilevered wings and tail unit, bereft of any external and, hence, drag-producing bracing struts or wires. Rushed through the design and assembly phases in order to compete in the second 1918 Adlershof fighter competitions, the disassembled D.I was dispatched by train immediately after its maiden flight. Reportedly, while still in transit, someone re-checking at the factory discovered that the upper wing attachment fittings were too weak and alerted Adlershof not to fly the aircraft until strengthened fittings could be rushed to them. Sadly, whether the information was not received, or simply ignored, the D.I was flown twice after re-assembly, Hermann Goring being the first service pilot to fly it, followed by Hptm Wilhelm Reinhardt, who lost his life after the upper wing detached in mid-air. At least two other D.Is were built, as two found their way to the US soon after the war, to be tested by the US Army and Navy, respectively. Earlier German testing had been critical of the aircraft's lack of speed, said to be 124mph at sea level, and general heaviness of the controls.
