From 08 to 20 April 2018, Leeuwarden Airbase again hosted one of the largest international fighter pilot exercises: Exercise Frisian Flag 2018.
For two weeks more than 70 fighter aircraft from various countries were exercising the execution of offensive and defensive missions, with the support of Airborne Warning and Control System, Electronic Warfare airplane, and Air to Air refueling tankers.
Air Refueling (AAR) was recognised in 2012 as a capability shortfall in Europe. To address this, the European Defence Agency has developed a European AR initiative looking at the three following objectives: increase the overall AAR capacity, reduce fragmentation of the fleet, and optimise the use of assets.
