Abstract
Systems, methods, and apparatuses are described for accelerating projectiles at high velocity. A barrel may include one or more heaters configured to heat a bore of the barrel prior to launch of a projectile. The barrel bore may be formed in a tungsten sleeve and may be heated to high temperatures. Heat from the barrel bore may be transferred to expanding propellant behind a projectile as it travels through the barrel bore.
