The AIM-9 Sidewinder is a heat-seeking, short-range, air-to-air missile carried by fighter aircraft and recently, certain gunship helicopters.
The Sidewinder was the first truly effective air-to-air missile, widely imitated and copied; yet its variants and upgrades remain in active service with many air forces after five decades.
Originally required to be locked and launched at a target from the rear, the more recent version's seeker head is all angle and doesn't require Top Guns to get behind their target.
