AAM
Air-to-Air Missile
An Air-to-Air Missile is a guided weapon launched from an aircraft to destroy another aircraft in flight.
Air-to-Air Missiles (AAMs) are the primary weapons used by fighter aircraft to engage and destroy enemy aircraft. They fall into two broad categories: short-range infrared-guided missiles like the AIM-9 Sidewinder that track an aircraft's heat signature, and medium-to-long-range radar-guided missiles like the AIM-120 AMRAAM that use active or semi-active radar homing to reach targets at distances exceeding 100 kilometers.
Modern AAMs have evolved dramatically since their introduction in the 1950s. Early missiles had poor reliability and limited maneuverability, but today's weapons feature thrust-vectoring control, high off-boresight targeting, and advanced seekers that can discriminate targets against ground clutter. The latest generation, including the AIM-260 JATM and Europe's Meteor missile, push engagement ranges even further while improving resistance to electronic countermeasures.
The development of AAMs fundamentally changed air combat. The era of guns-only dogfighting gave way to beyond-visual-range engagements where the first aircraft to detect and launch often wins. This shift drove the emphasis on stealth, sensor fusion, and situational awareness that defines modern fighter design.

BVR(Beyond Visual Range)
Beyond Visual Range describes air combat engagements conducted at distances where pilots cannot see the opposing aircraft, relying instead on radar and long-range missiles.
WVR(Within Visual Range)
Within Visual Range describes air combat conducted at close distances where pilots can see the opposing aircraft, relying on short-range missiles, guns, and aircraft maneuverability.
IFF(Identification Friend or Foe)
Identification Friend or Foe is an electronic system that allows military platforms to interrogate nearby aircraft, vehicles, or ships to determine whether they are friendly or hostile.
