Junkers CL.I

The Junkers CL.I was one of the few aircraft in the German Empire that were covered almost entirely with metal instead of wood and thus protected the pilot and the observer much better against fire.


Development and construction:

With the outbreak of the First World War, the production of Junkers & Co. for civilian goods came almost completely to a standstill and mainly field kitchens were produced for the German army.

In 1915, the designer Hugo Junkers developed the world's first all-metal aircraft, the J1. In the following years, several successor models were developed, but did not go beyond the status of the prototype.

It was not until the development and production of the Junker J.I ground combat aircraft that a basis was created that led to the development of the CL.I in early 1918.

Full metal cladding protected the pilot and observer from enemy fire, as in previous models, and enabled them to attack more effective targets on the ground. For these attacks either the assembled machine guns were used or bombs and hand grenades, which were attached to small containers on the observation stand.

Use in the First World War:

In the summer of 1918 began with the production of aircraft. For the first series 43 machines were initially planned, but by the end of the war only six could be completed.

In contrast to the Junkers J.I the CL.I was no longer used at the front, but by Freikorps in Finland and the Baltic States in the fight against the Communists until the year 1919.

Fokker Dr I Aces of World War 1 (Aircraft of the Aces)

Fokker Dr I Aces of World War 1 (Aircraft of the Aces) Paperback – Bargain Price, August 25, 2001

Undoubtedly the most famous fighter type to see service on either side during World War 1, the Fokker Dr I was a revelation when it entered service on the western front in 1917. Manfred von Richthofen’s JG 1 ‘circus’ was the first Jasta to completely re-equip with the new fighter, and in the skilled hands of its numerous aces the Dr I proved a formidable opponent. The Dr I remained in service on the Western Front until replaced by the superior Fokker D VII in May 1918. Just weeks prior to that, however, Germany’s leading ace, the great ‘Red Baron’, had been killed at the controls of a Dr I.
