In Memoriam

Klaas Willem Jonker
† April 30, 2018

On Monday 30 April 2018, Wilko Jonker died after a long illness at the age of 58. He leaves behind a wife and two children. The Dutch military aviation and plastic modeling were his hobby and on this website he shared all the knowledge he has collected over the years. His hobby has been able to distract him from the persistent disease in his body until the last week of his life. The contacts with other hobbyists were a major support for him.

This website will be maintained by different people for as long as possible, so that other enthusiasts can continue to benefit from extensive content.

Caudron G.IV


The Caudron G.IV was a development of the single engined Caudron G.III. This aircraft, a reliable scout had as he disadvantage that no weapons could be carried. The first flight of the Caudron G.IV was in March 1915.

The wingspan had been enlarged, four rudders and two engines were added, so an armed gunner/observer and a bomb load of 100 kg could be carried.

The aircraft was used as scout and bomber and could penetrate the German. Later, when improved German fighters entered service, the Caudron G.IV was used for nightly operations.

The Caudron G.IV was used by Belgium, France, Finland, England and the US.

A total of 1358 examples were built in France plus an additional 51 examples by A.E.R., Italy and 12 examples by the British Caudron factory.


Three versions were built:

Caudron A2:
a scout, equipped with radio;
Caudron B2:
a bomber, could carry 100 kg bombs;
Caudron E2:
a trainer with double steering.

The Caudron G.IVB was an armoured version.

In 1915 five examples of this two seat bomber were ordered, but because of the war there were many problems to transport the aircraft to the Netherlands. Because of these problems the aircraft arrived on June 24, 1918.
As they had been stored for a long period of time, a complete overhaul was necessary.

The Caudron G.IV was completely outdated in 1918 and were mainly just for reconnaissance duties.
In 1925 the Caudron G.IV was withdrawn from use.
