Galax Viper volley gun
From Wookieepedia, the Star Wars wiki.
The Galax Viper volley gun was an anti-vehilce gun produced by Kurtough during the early years of the New Republic. A large weapon, the Galax Viper employed a collection of missile launchers in a single unit, each designed to fire shortly after the previous one. This produced a "curtain effect," with a continuous volley of projectiles striking the vehicle and eliminating most deflector shields.
