Blackstar Cluster Launcher
From Warhammer 40k - Lexicanum
The Blackstar Cluster Launcher is an array of two six-barreled Grenade Launchers mounted on the rear of Deathwatch Corvus Blackstar gunships. These allow the pilot of the Blackstar to sow a hailstorm of munitions in his wake as he strafes the primary target. The launcher is capable of firing either fragmentation or incendiary munitions.[1]
