Albatros D XII (with Bohme undercarriage)
  At least two D XII prototypes were built. D 2210/18 was first flown in March 1918 and participated in the second D types Competition. A modified machine fitted with a Bohme undercarriage which featured compressed-air shock absorbers flew in April 1918. This undercarriage necessitated an additional strut, which may just be observed running vertically above the wheel in the above photograph. The D XIIs again featured the slab-sided ply-covered fuselage introduced with the D X. There was again a variation in the ailerons, the Bohme undercarriage machine having unbalanced ailerons of inverse taper, and D 2211/18 having overhung balanced ailerons of parallel chord. Engine, 160 h.p. Mercedes D III. Span, 8.2 m. (26 ft. 10 7/8 in.). Length, 5.785 m. (18 ft. 11 3/4 in.). Height, 2.8 m. (9 ft. 2 1/4 in.). Area, 19.84 sq.m. (214 sq.ft.). Weights: Empty, 580 kg. (1.276 lb.). Loaded, 760 kg. (1,672 lb.). Speed, 180 km.hr. (112.5 m.p.h.). Climb, 8,000 m. (26,240 ft.) in 54 min. Duration, 1 hr. Armament, twin Spandau machineguns.
  The second D XII (2211/18) was fitted with B.M.W. IIIa engine of some 185 h.p. and participated in the third D types Competition in October 1918.

One of Albatros's less notable designs, their D XII. The first of the two D XII built used a 180hp Mercedes DIIIa and first flew in March 1918, the second, powered by a 185hp BMW IIIa, following it into the air a month later. Top level speed of the first D XII, seen here, was cited at 115mph at sea level. The second aircraft took part in the third of the 1918 fighter design competitions, held in October.
