OVERVIEW: The AIM-120C-4 AMRAAM is a beyond-visual-range, fire-and-forget, active radar-guided air-to-air missile, upgraded under the P3I Phase 2 program for enhanced ECCM and lethality.

DETAILS: The AIM-120C-4 was part of the Phase 2 upgrade in the AMRAAM Pre-Planned Product Improvement (P3I.2) program. with a 23 kg blast-fragmentation warhead, It featured internal enhancements aimed at improving effectiveness in electronically contested environments. These included upgraded electronic counter-countermeasures (ECCM), improved mid-course datalink guidance, and a refined active radar seeker for superior terminal tracking. The missile maintained the clipped-fin design introduced in the AIM-120C for compatibility with internal bays of stealth aircraft such as the F-22 Raptor. Its electronics improvements enabled better performance against maneuvering targets and radar jamming techniques.
