WebRotating Band. The rotating band is a cylindrical ring of comparatively soft metal that is pressed into a knurled, or roughened, groove near the base of the projectile. WebThe purpose of these rotating bands is to guide the projectile inside the barrel when it is discharged and cause it to rotate (spin) around the longitudinal axis. Rotating bands of … These projectiles consist of two major components, a warhead filled with 16 pounds (7.3 kg) of Composition B high explosive (M549) or 15 pounds (6.8 kg) of TNT high explosive (M549A1), and a solid propellant rocket motor. These components are threaded together so that the outer steel shells of both form a streamlined ogive. A supplementary charge is installed in the deep cavity of the nose.
