In Memoriam

Klaas Willem Jonker
(Wilko)
† 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.

Halberstadt CL.IV

History

The CL.IV was designed as successor of the CL.II, an effective ground support aircraft. The design was specially focused on this task.
The CL.IV had a shorter, strengthened fuselage and an enlarged horizontal tail. These modifications gave the aircraft an improved manoeuvrability compared with the CL.II.
450 examples were built by Halberstadt and LFG (Roland) built another 250 examples.
