Ming Dynasty Folangji Cannon

Timeline

1. 1368–1450City defenses of Nanjing and Beijing · JiangsuBuilding on Yuan-era cannon technology, the early Ming Armaments Bureau cast bowl-mouth cannons, cup-mouth cannons, and general's guns, placing them on city towers, passes, and naval warships. These muzzle-loading heavy guns formed the basis of Ming city-defense artillery and also accompanied the army on the Yongle northern campaigns.
2. 1451–1460Fortresses along the Ming Great Wall's Nine Borders · North ChinaAfter the Tumu Crisis, the Ming court vigorously repaired Great Wall passes during the Jingtai era and added various heavy city-defense guns; bowl-mouth cannons and other large wall guns were systematically deployed at key positions such as Xuanfu, Datong, and Juyong Pass, forming a three-tier long-, medium-, and short-range fire system with hand cannons and bows and crossbows. The city-defense artillery experience of this period laid the technical groundwork for the later introduction of the Folangji cannon.
3. 1521–1570Guangzhou and the southeast coast · GuangdongAfter the Folangji cannon (Falcão/Falconete-type breech-loader) carried by the Portuguese reached China, the Ming court ordered craftsmen to copy it; within a few years it was issued on a large scale to the navy, frontier armies, and the capital garrison. With its interchangeable swivel chambers and rate of fire far exceeding muzzle-loaders, it rapidly replaced older wall guns and became one of the iconic heavy firearms of the mid-to-late Ming.
