They are stabilized in flight by fins, or canted nozzles, that are attached to the motor. The warhead is the portion of the rocket that produces the desired effect. It can be filled with explosives, toxic chemicals, WP, submunitions, CS, or illumination flares. The motor propels the rocket to the target. The fuze is the component that initiates the desired effect at the desired time.
Rockets use the same type of fuzing as projectiles and mortars.
The fuze may be located in the nose or internally between the warhead and the motor. Some rockets are spin stabilized. Unlike projectiles and mortars, these rockets do not have rotating bands. The presence of motor nozzles, or venturies, in the rear of the rocket motor can be used for positive identification purposes for this type of ordnance. Generally, the rocket motor will not create an additional hazard, because the motor is usually burned out shortly after the rocket leaves the launcher.
