A finless mortar tube made of a superalloy includes, seriatim, a breech end, a beginning taper point, an ending taper point, a lower clamp region, an upper clamp region, and a muzzle end. The nominal wall thickness of the tube is constant from forward of the breech end to the beginning taper point and the nominal wall thickness of the tube decreases from the beginning taper point to the ending taper point. The mortar tube is capable of a substantial increase in the rate of fire compared to conventional mortar tubes.
