Abstract: A system for firing shell-cased projectiles including multiple barrels and a breech assembly, which includes multiple detonators each aligned to a corresponding one of the barrels. Each detonator may include a plunger coupled to a firing pin, and a solenoid for driving the plunger and firing pin toward the corresponding barrel upon firing, and an actuator-driven mechanical safety device including a slide plate switchable between first and second lateral positions. The slide plate may include multiple entrapment pins, each corresponding to one of the detonators. When the slide plate is in the first lateral position, each of the entrapment pins are positioned so as to obstruct movement of the plunger in the corresponding detonator, thereby rendering the corresponding detonator inoperable to fire even if the corresponding solenoid is actuated. On the other hand, when the slide plate is in the second lateral position, each of the detonators is operable to fire when the corresponding solenoid is actuated.
