Loss of separation between Swedish JAS aircraft and French Mirage aircraft

During a military exercise in northern Sweden, a group of four Swedish combat aircraft of the type JAS 39 Gripen was travelling in a trail formation at a height of 22,000 feet. At the same time, two French combat aircraft of the type Mirage 2000C travelled in the opposite direction at an altitude of 27,000 feet. The French aircraft descended and came to pass one of the Swedish aircraft at a lateral distance of 150 meters and 100 feet in height. The pilots discovered each other visually a few seconds before the passage. No avoidance action was performed.

SHK has assessed the occurrence as a serious incident and initiated a safety investigation.
