Mechanism: "Growler" Class Turret
Automated defense system.

Lightly armored gun used for point defense. Fast targets can evade its tracking system. The GM-42 "Growler" Class Turret is a dated design, though still quite effective as a point-defense system. It is lightly armored, and fast-moving targets can evade its tracking system. Several copies of the system exist, including the Space Pirate "Humility" Class automated turret.
