Aviatik D III
  Emerging from the Aviatik workshops in late 1917, the D III was another experimental type, and two prototypes were built. Both aircraft took part in the second D types Competition at Adlershof in 1918. During two test climbs to 5,000 m. (16,400 ft.) times of 20.5 min. and 22.5 min. were recorded. In order to obtain an increase in gap, the lower wings were mounted on a small keel extended from the fuselage. As in the D II, the fuselage was plywood covered, the cylinder-heads of the ungeared 195 h.p. Benz IIIb vee-eight motor being left well exposed. Span was 9.0 m. (29 ft. 6 3/8 in.) upper and 8.04 m. (26 ft. 4 5/8 in.) lower, with an area of 21 sq.m. (226.8 sq.ft.). The gross weight was 864 kg. (1,901 lb.).

  Flown for the first time in November 1917, the first prototype D III was powered by an ungeared Benz Bz IIIbo eight-cylinder Vee engine rated at 195 hp, was of mixed construction with a steel-tube forward fuselage, plywood fuselage skinning and fabric wing skinning, and carried an armament of twin synchronised 7,92-mm LMG 08/15 machine guns. A distinguishing feature was provided by a small, keel-like extension beneath the fuselage which served to increase the wing gap. Initial Typen-Prufung was performed at Adlershof during 9-12 February 1918, and after modifications by Aviatik, the D III was returned to Adlershof in April for resumption of type testing, together with a second prototype powered by a geared Bz IIIbm engine. By this time a small series of Bz IIIbo-powered D IIIs was under construction for service test and evaluation. Performance of the D III was considered to be superior to that of the Albatros D V although no details have apparently survived other than those relating to climb tests conducted in March 1918 with the Bz IIIbo-powered first prototype.

Time to 3,280 ft (1 000m), 2.5min, to 6,560ft (2 000 m), 5.7 min, to 9,840 ft (3 000 m), 11 min, to 13,125 ft (4 000 m), 17 min.
Loaded weight, 1,905 lb (864 kg).
Span, 29 ft 6 3/8 in ((9,0 m).
Wing area, 226.5 sq ft (21,0 m2).

The Aviatik, Type D III
  In 1918 another single-seater type was brought out. This machine, which had the series number D III, was fitted with a Vee type 195 h.p. eight-cylindered high-speed Benz engine. As other machines of the D type it had one pair of struts aside, and it was similar to the type C VIII, in that it had a keel structure projecting down from the bottom of the fuselage, to which was attached the bottom plane. The planes were heavily staggered, so as to give the pilot a better view. The radiator was placed in the top plane.

The Aviatik DIII lirst appeared in late 1917 but two were entered for the 1918 fighter competition. Despite a reasonable performance it was up against superb designs such as the Fokker DVII and so was abandoned.
