In the early 1990’s, the Belgian Air Force had a requirement for significant improvements in aircraft availability and, at the same time, to reduce support costs and complement levels. ILIAS has been specifically designed and built to address these needs and was put into production for the Air Force in 1997.

As part of a strategic plan, in which the entire Belgian Defense organization was re-structured; the Air Force, Navy and Army ceased to exist and became the Air, Navy, Land and Medical components, with a number of shared functions like Material and Human Resources. As a consequence, all four components started using ILIAS as an unique system for the material management of all materials in the organization.
