a. Ground-to-ground rockets are large (762-millimeter), free flight, solid propellant field artillery ammunition. They follow a ballistic trajectory similar to cannon-fired artillery projectiles, and are stabilized in flight by a combination of spin and fins. They have a maximum range capability of approximately 35,000 meters.
b. The complete round (fig. 5-12) consists of a warhead section, motor body and fin assembly. The fuze is considered a component of the warhead. The most commonly used is a mechanical time fuze which can be set to function at 5 to 120 seconds.
c. These rockets are distinguished by an assembly of spin rockets mounted in pairs around a pedestal assembly located between the warhead and the motor. When ignited, the spin rockets produce thrust which imparts a clockwise spin to the rocket and reduces the effects of misalinement. Spin is maintained in flight by the cant of the tail fins. The rocket is fired by remote control from a rail launcher.
