During OPERATION ALLIED FORCE, the 79-day NATO air campaign in former Yugoslavia from March to June of 1999, Canada committed 18 CF-18s to TASK FORCE AVIANO, flying from Aviano Air Base in northern Italy. CF-18s flew 678 sorties, in the air-to-ground and air-to-air roles using both precision guided munitions and unguided "iron" bombs. With much less than 10% of the aircraft committed to the campaign, Canadian aircraft conducted 10% of the NATO strike sorties during the campaign.
