The most commonly used firearm during the Revolutionary War was the muzzle-loaded musket. The musket was the primary weapon for thousands of British and Continental Army soldiers. Revolutionary War muskets were commonly equipped with bayonets, which were useful against cavalry and in close combat. America's ability to arm its force with flintlock muskets as they mobilized was a critical challenge early in the war.
Muskets used in the Revolutionary War included the Brown Bess, the Charleville, and the Kentucky long rifle.
The cannon was a highly effective weapon throughout the Revolutionary War and was key to the American victory.
America first experimented with the concept of an underwater vessel during the Revolutionary War. A submarine, then called "the Turtle" was invented by David Bushnell in order to attach explosives to British ships without being detected.
