Production of the Mirage IIIS developed into a scandal. Although the Air Force staff wanted to acquire the best available aircraft on the market, neither it nor the Federal Council had issued performance specifications. The concept of mobile defense had replaced static defense, such as the Réduit strategy of World War II, as the doctrine of the Swiss Armed Forces. The new doctrine required greater numbers of long-range aircraft and tanks in order to combat Soviet troops before they arrived near the Swiss border. The committee on aircraft procurement, which consisted of two military officers and an engineer who was employed by the army, originally proposed "at least 100 Mirages" to be employed in a multi-role capacity.
