The GM-42 "Growler" Class Turret is a dated turret used by the Galactic Federation. Despite its age, it is still considered very effective as a point-defense system. They are lightly armored and are similar to Auto Defense Turrets from Metroid Prime. They can deal a fair amount of damage, though can be easily avoided by agile enemies. A single Missile or a Charge Beam shot from any beam polarity will destroy the turret. Samus Aran encounters these turrets in the hallways of the GF base in the Temple Grounds of planet Aether. Space Pirates were able to steal the designs for the turret and created an advanced version, known as the Humility Class Turret.
