Ball bearing missile
From Wookieepedia, the Star Wars wiki.
Ball bearing missiles were an anti-dovin basal weapon used in Twin Suns Squadron during the Yuuzhan Vong Invasion. It consisted of an open metal tube packed with a plasma-based explosive. The other end was packed with multiple ball bearings, that, when superheated by the detonated charge, could penetrate the dovin basal's defenses.
