A.E.G. P.E.
  This experimental single-seat triplane appeared early in 1918. It featured dural tubular wing spars and the aluminium-sheel-covered fuselage was also armoured. It was from this aircraft the later DJ I stemmed. It is certain a vee-eight-type motor was fitted, probably the 195 h.p. Benz Bz IIIb as in the DJ I. Span, 11.2 m. (36 ft. 9 in.). Length, 6.6 m. (21 ft. 7 7/8 in.). Weights: Empty, 1,182kg.(2,600 lb.). Loaded, 1,412kg.(3,106 lb.). Speed, 166 km.hr. (103.75 m.p.h.). Climb, 1,000 m. (3,280 ft.) in 5.8 min. Armament, two Spandau machine-guns firing forward and four small bombs.

A.E.G. PE Germany

  The PE (Panzer-Einsitzer) was a single-seat armoured ground attack fighter and proved to be unique among aircraft designed for this task in being of triplane configuration. Featuring an armoured light alloy-covered fuselage and fabric-covered dural wings, the PE was powered by a 195 hp Benz Bz IIIb eight-cylinder water-cooled engine and was first flown in March 1918. Armament consisted of two synchronised 7,92-mm LMG 08/15 machine guns supplemented by racks for small bombs. The PE proved easy to fly but was found to have poor stability and was considered by the Idflieg (Inspektion der Fliegertruppe) to possess inadequate performance for fighter-versus-fighter combat, a dedicated ground attack aircraft being considered unacceptable. Nonetheless, A.E.G. was to persist with the concept with the DJ.

AEG DJ.I Triplane

  Exactly when the idea of an armored, single-seat fighter to oppose Allied ground-attack aircraft was proposed is not known. Surely the concept was another inspiration of Oberst-Leutnant Wilhelm Siegert, the commander of Idflieg, who throughout the war remained a steadfast proponent of specialized aircraft to fulfill specific tactical assignments. He had no use for general-purpose aircraft. It was reported on 21 October 1917 that AEG was designing an armored fighter, known internally as the AEG PE (Panzer-Einsitzer) and may have been later designated DJ.I or DA.I. (In late 1918, two aircraft classifications appeared in various records, both signifying the armored single-seat fighter. They were DJ = D-Infantrie and DA = D-Angriff (attack). It is not known if these classifications were officially adopted.) The engine, fuel, and pilot were protected by a steel shell forming an integral part of the airframe. The rear fuselage was of aluminum. The triplane wings had AEG's customary steel-tube spars and wooden ribs.
  The preliminary trials of the AEG PE triplane, powered by a 195 hp Benz Bz.IIIb V-8 engine, were expected to be concluded in December 1917. From a report dated March 1918, we learn that the AEG Panzer-Einsitzer had reached 4000 meters (13,123 ft.) in 48 minutes. The test pilot reported the triplane as easy to fly but not particularly fast. Work on the AEG DJ.I triplane was stopped in May 1918 because of "poor flight characteristics."

J.Herris - AEG Aircraft of WWI /Centennial Perspective/
The AEG DJ.I triplane was envisioned as a low-altitude fighter armored to withstand ground-fire as it intercepted enemy ground-attack aircraft at low altitude, a role similar to that foreseen for the Sopwith Salamander. It was powered by a 195 hp Benz Bz.IIIb V-8 engine, which did not reach production in time to power any warplane over the front.
