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.

Albatros D.XII 2210/18 shown here in front of the Albatros factory at Johannisthal in May 1918 was powered by a 170 hp Mercedes D.IIIa.

The Albatros D.XII 2210/18 powered by the Mercedes D.III was evaluated in July, where it was judged slightly inferior to the Pfalz D.XII and was not chosen for production. The modified D.XII 2210/18 shown here was now powered by the 185 hp BMW.IIIa and competed at the Third Fighter Competition. The D.XII was the last Albatros fighter design flown during the war and the last chance for Albatros to regain its former place in fighter design.

Albatros D.XII 2211/18 powered by the Mercedes D.III featured a longer fuselage, modified wing, and aerodynamically-balanced ailerons.Tests were still in progress on this airframe as late as September 1918 as Albatros's final attempt at a replacement for the Albatros D.Va. The D.XII now had good flying qualities but was not robust enough despite its extensive wire bracing, which created too much drag and made it slower than other competitors.
