A rifled cannon is a type of artillery that features spiral grooves cut into its barrel. These grooves cause the projectile to spin as it is fired, improving accuracy and range compared to smoothbore cannons. The design allows for greater stability in flight, making rifled cannons more effective on the battlefield. Rifled cannons became prominent during the 19th century, particularly during the American Civil War and Crimean War. They were used to fire various types of ammunition, including explosive shells and solid shot, significantly enhancing the firepower of military forces.
