The AIM-9 Sidewinder is one of the two air-to-air missiles available in every playable aircraft, available right from 3-1 in License Mode (in the original game). In aimStrike!, it is separated into two variants.
Description[]
The missile has slightly shorter range (beginning to gain missile lock at the point where the AMRAAM would be ready to fire), but higher mobility and lower weight compared to the games' only other air-to-air missile, the AIM-120 AMRAAM.
