Twinfold KBD on a huge number of naval guns

The twin KBD Gatling gun on the Giant Naval Gun is a manual, multi-barreled rotary machine gun. The Gatling machine gun was designed by the American Richard Jordan Gatling (whose name is translated as Grimm, so the gun is also translated as the Grimm machine gun or translated as the Getter machine gun/machine gun) in 1860, and it was the first large-scale practical machine gun in the world. Around 1874 (the thirteenth year of Tongzhi in the Qing Dynasty), the Gatling machine gun was imported into China, and it was called "Green Cannon" or "Green Fast Cannon" at that time. After the 50s, the Gatling principle was first applied to firearms and small-caliber aircraft guns and anti-aircraft guns by the United States after being re-improved, and the machine gun using this principle is the fastest rate of fire, and the continuous rate of fire of today's various Gatling weapons can generally reach more than 1,000 rounds per barrel per minute.
