20mm Quad Turrets

The 20mm Quad Turrets first appear in Book 8 of Grimm's Military Sci-Fi Series as a critical defensive system aboard the flagship vessel. These eight turrets employ staggered barrel firing to provide layered protection against incoming torpedoes and close-range threats, marking a significant upgrade in point-defense capabilities. Their introduction represents the culmination of evolving naval warfare tactics throughout the series, transitioning from earlier kinetic and energy-based defenses to a hybrid system optimized for rapid, overlapping fire patterns.
