What mechanism primarily achieves the kill in the AIM-120 warhead?

• A. Fusion charge
• B. Warhead casing rupture
• C. Fragments
• D. Shaped charge

Answer: (C)

Fragmentation is the primary kill mechanism because the AIM-120’s warhead is designed to explode into a cloud of high-velocity metal fragments. When the explosive detonates, thousands of fragments spray outward and impact the aircraft’s skin, fuel lines, engines, and avionics, causing widespread damage and likely loss of control or power. A shaped charge would produce a focused jet to pierce armor, which isn’t as effective against the relatively lightly armored airframe and systems of an aircraft. A nuclear (fusion) charge isn’t used in this type of missile. Warhead casing rupture is simply how the fragments are released; the actual lethal effect comes from the fragments themselves.
