Fokker M.22 / D.V

D.V (M.22E)

The D.V (M.22E), armed with a single machine gun, was a design by Reinhold Platz. It was the most manoeuvrable aeroplane of its time, but owing to problems with the Oberursel engine it was not a success. Of the 300 built, most were used for training purposes.
The final D V was a refined version of the D III with the U.l engine, and was used as a trainer.

Engine: Oberursel U.l rotary, 75-kW (100-hp).

Fokker M.19 / D.III

In an effort to maintain an edge over Allied fighters, the D III had more power, a fuselage based on that of the D II, D I wings and an armament of two machine-guns.

Ten D.IIIs (M.19Ks) were purchased by the LVA (Dutch Aviation Department) in Germany. Some 23 were built, but were not successful in spite of the fact that Boelcke shot down six opponents with this type. With a 160 h.p. Oberursel engine the maximum speed was 160 kph.

D III
Engine: l x Oberursel U.lll, 119kW (160hp).
Span: 9.05m (29ft 8.25in).
Length: 6.3m (20 ft 8 in).
Armament: 1 or 2 x 7.92-mm (0.312-in) LMG 08/15 mg.
Max T/O weight: 710kg (1,565lb).
Max speed: 99 mph at sea level.
Operational endurance: 1 hr 30 min.

Fokker M.18 / D.I

To replace its E-series monoplanes, in the summer of 1916 Fokker evolved the D I biplane fighter from its M.18z prototype.
The D.I had a 120 h.p. Mercedes engine, but looked very much like the D. II. Martin Kreutzer lost his life whilst testing a D. I Although 136 were built, the type proved too slow for use on the Western Front.

Engine: Mercedes DII, 89-kW (120-hp).

Fokker M.17 / D.II

D.II (M.17ZF)

The D II appeared later than the D I but was derived from the earlier M.17z prototype. The D II had shorter wings and a longer fuselage, and as it was powered by a 75-kW (100-hp) Oberursel U.l rotary engine it was lighter and more manoeuvrable than the D I.
M.17E, a version of the M.16E with a 100 h.p. Oberursel rotary engine instead of the liquid cooled Mercedes of the latter. Equipped with one machine gun, the M.17E was not put into production.
The D.II (M.17ZF) fighter, designed by Martin Kreutzer, appeared early 1916 and was completed before the D.I. With a 100 h.p. Oberursel engine it attained a speed of 150 kph, and the armament comprised one machine gun. A total of 77 of this type were produced.

Engine: Oberursel U.l rotary, 75-kW (100-hp).

Fokker M.15 / E.IV

The E III was superseded by the generally similar E IV. The final attempt to wring extra capability out of the basic design was the overweight E IV with two guns and the 119-kW (160-hp) U.III rotary.

Total E-series production was about 300 aircraft, including 49 E.IV, the last in July 1916.

Engine: 119-kW (160-hp) Oberursel U.III rotary.
