Fokker built a total of 22 M types, plus a number of variants.
Most of the M designs were from Martin Kreutzer .
Production began in Johannistahl and then moved to the Fokker factory in Schwerin. Production took place from 1912 to 1916.

A number of M-types were also built under license by MAG (Magyar Általános Gépgyár; Hungarian General Machine Factory) in Hungary.
The first M versions were further developments of the Spin, so the first M-type, the M.1, is a further development of the second Spin variant from 1913.

The “M” designation stands for “Militär flugzeug”, but both the German and other armies also gave their own military type designations to a number of M versions.
The familiar "E" designation (Eindecker) originated with the German army. They also used the "D" (Doppeldecker) designation for several M types.
Photos of the derived D and E types will be posted with the respective articles about the D-serie and E-serie.

Besides Germany, Fokker supplied M aircraft to Turkey and the Austro-Hungarian Army (which used the AI, A-II, A-III, B-I, B-II, and B-III designations). The Austro-Hungarian Army was designated KuK, which stood for "Kaiserlich und Königlich" (King and King).

The M.19K (D-3) operated with the LVA (Aviation Department) in the Netherlands.
Also one M.8 (A-1) with registration LA-34 was in service with the LVA.

There were single and biplanes within the M-types and they were usually equipped with Mercedes water-cooled inline engines or Oberursel air-cooled rotary engines of various horsepower.

Occasionally, Renault V engines, Siemens-Halske and Goebel rotary engines have also been used.

Most M types were armed, among other things, with synchronized machine guns .
A number of M types were used for reconnaissance, observation and training flights, but most M types were used as fighter aircraft.

Due to the large number of M types produced, the engine and arms supply to Fokker was jeopardized.
Fokker solved this problem with his own arms factory in Reinickendorf near Berlin and became the largest shareholder in the Oberursel engine factory, thus guaranteeing engine deliveries to him.
