128 mm artillery

128 mm artillery typically refers to a type of large-caliber artillery weapon system that fires projectiles of 128 millimeters in diameter. This caliber is not as commonly referenced as standard artillery sizes like 105 mm or 155 mm, but there are some notable systems associated with this caliber. One of the most recognized pieces of artillery in this classification is the **128 mm anti-aircraft gun** used by Germany, notably the **Flak 40**, which was designed during World War II.
