In week 39 & week 40 of 2021 the final stage of the Weapons Instructor Course (WIC) took place at Leeuwarden Air Base in the Netherlands. During this large-scale final exercise the German Air Force came to Leeuwarden with six Tornado IDS & ECR aircraft and eight Eurofighter EF2000 aircraft. The final stage of the training is called the Weapons School Integration Phase (WSINT). In this part of the WIC multiple complex scenarios are flow pushing the participants to their maximum efforts. Next to the Germans also the Norwegian F-35A Lightning II aircraft are already for several weeks active at the Frisian air base. Leeuwarden is for many participants in the course an ideal location due to its position close to the North Sea and the opportunity to train at the Cornfield Range.
