From Halopedia, the Halo wiki
ASGM-15 "Shield Buster" missiles are a type of ordnance employed by UNSC strikecraft, including Longsword fighters. The EMP-assisted missiles use an initial burst of electromagnetic energy to penetrate energy shielding before delivering a hull-penetrating explosive charge. The missiles are considered powerful enough to down an Intrusion corvette.
