300 mm artillery typically refers to large-caliber artillery pieces that fire projectiles with a diameter of 300 millimeters (30 cm). This size of artillery is often associated with heavy howitzers or siege guns, which are designed for long-range bombardment and can deliver powerful explosive shells over significant distances. Historically, 300 mm artillery has been used in many military conflicts and can be mounted on both towed and self-propelled platforms.
