As dawn breaks over the choppy waters of the Black Sea, the Russian Ivan Gren-class amphibious assault ship Pyotr Morgunov slices through the waves, its crew on high alert. Tasked with securing maritime routes in the region in the midst of the conflict with Ukraine, this vessel is armed with one of the world’s fastest naval gun systems: the AK-630M-2 “Duet” autocannon. Nicknamed by some “The God of Fire,” with its twin 30-millimeter rotary cannons capable of unleashing a staggering 10,000 rounds per minute, the “Duet” stands ready to counter any threat, be it aerial, surface, or even small, fast-moving targets.Suddenly, Pyotr Morgunov’s radar detects an incoming anti-ship missile fired from a Ukrainian coastal battery. The crew springs into action as the AK-630M-2 locks onto the missile, its advanced fire control system calculating trajectories with precision. The ship’s captain gives the order, and in an instant, the sky is filled with the deafening roar of gunfire.The “Duet”’s barrels rotate with a blur of motion, spewing a lethal stream of projectiles that cut through the dawn light like a swarm of locusts. The missile is targeted with pinpoint accuracy, exploding mid-air before raining harmless debris into the sea below.
