O.Thetford, P.Gray German Aircraft of the First World War (Putnam)
A.E.G. DJ I
This aircraft was designed as an armoured single-seat ground attack fighter, roughly equivalent to the British Sopwith Salamander. It first flew in September 1918, but the Armistice stopped further development. Braced with two bay I struts, it had no flying or landing cables. The fuselage was skinned with sheet aluminium. Engine, 195 h.p. Benz Bz IIIb vee eight, driving four-blade airscrew. Span, 10.0 m. (32 ft. 9 3/4 in.). Length, 6.69 m. (22 ft. 11 1/4 in.). Height, 3 0 m. (9 ft. 10 1/8 in.). Weights: Empty, 1,185 kg. (2,607 lb.). Loaded, 1,370 kg. (3,014 lb.). Speed, 180 km.hr. (112.5 m.p.h.). Climb, 1,000 m. (3,280 ft.) in 4 min.

A.E.G. DJ I Germany
Pursuing the concept of the single-seat armoured ground attack fighter, A.E.G. had begun the development of an aerodynamically advanced biplane as a Panzer-Einsitzer before the initiation of flight testing of the PE triplane, and this, the DJ I, was to be flown in July 1918. Two prototypes of the DJ I were completed with the 195 hp Benz Bz IIIb engine and a third prototype with the 240 hp Maybach Mb IVa engine, armament standardising on twin synchronised 7,92-mm LMG 08/15 guns with provision for anti-personnel bombs. An equi-span two-bay biplane, the DJ I wing cellule dispensed with flying wires, interplane bracing being provided by I-section struts. The wings were of dural construction with fabric covering, and the fuselage, which embodied some armour protection for the engine, fuel tank and pilot, had sheet aluminium skinning. Hostilities terminated while flight testing of the DJ I was still in progress. The following data relate to the Benz-engined version.
