Naglo Quadruplane
Built by Naglo Bootswerft of Spandau, Berlin, in 1918, this experimental single-seater was based on an Albatros D V type fuselage. The manner in which the bottom wing was attached to an extruded keel and braced with splayed struts, completely independent of the three main lifting surfaces, conveys the impression it was added as an afterthought. The machine was listed under serial D 1161/18 as Naglo D II for the second D types Competition at Adlershof in the summer of 1918, but no record of performance figures is available. Design was by Ing. Gradig, who was still with Albatros and, as a result, he was dismissed by that firm. The official type test was undertaken on 24th May 1918, but the machine was rejected at the request of Schubert of Albatros. Engine, 160 h.p. Mercedes D III. Span, 9.0 m. (29 ft. 6 3/8 in.). Area, 22.4 sq.m. (242 sq.ft.). Weights: Empty, 724 kg. (1,593 lb.). Loaded, 914 kg. (2,011 lb.).

The Naglo D.I quadraplane fighter prototype. More wings increased both lift and drag, and fighters needed to be fast as well as maneuverable. Generally, multi-planes were slow.
The Mercedes D IIIa was the most popular fighter engine and was used in the bizarre Naglo D.I, a quadraplane inspired by the Albatros fighters. -

The Naglo D.I quadraplane fighter prototype. Span was 9 meters and it was powered by a 160 hp Mercedes D.III. Its biplane development the D.II, serial 1161/18, was evaluated in conjunction with the Second Fighter Competition. These photos are incorrectly marked 'D.II'. (Peter M. Grosz collection, STDB)

The Naglo D.I multiplane was one of the last gasps of Germany's 'Triplane Craze'. It was inspired by the Albatros D.V and designed by an engineer employed by Albatros; he was fired for his efforts. It featured excellent workmanship and poor design; the weight and drag of all its struts and wings ensured it had lower performance than the biplane that inspired it.

The Naglo D.II fighter was a biplane development of the D.I quadraplane and competed at the Second Fighter Competition. This accurate Idflieg drawing shows it but no photos have survived. It may have used the fuselage of the D.I fitted with biplane wings as it retains the wing-mounting pylon under the fuselage. (Peter M. Grosz collection, STDB)
