Cluster missile
From Wookieepedia, the Star Wars wiki.
A cluster missile was one of a group of low-powered, unguided concussion missiles that would rapidly fire in the direction that the starship which carried them was pointing. If a ship changed course while firing the missiles, the missiles that had not been fired yet would change their direction also, instead of seeking out the previous target.
Additionally, an upgraded, target-seeking variation of cluster missile was available. Rather than firing in a standard formation, each of the six missiles could seek an individual target, or strike as a unified assault against a single ship.
