PRACTICE WARHEADS.- Practice warheads are either dummy configurations or inert-loaded service warheads. In the inert-loaded service warheads, the weight and placement of the filler gives the practice warhead the same ballistic characteristics as the explosive-loaded service warhead. A steel nose plug is assembled in the practice heads in place of the nose fuze. The entire surface, except for the stenciled marking, is painted blue. The practice warheads currently in use are listed in table 2-2.

normal transporting, handling, and launching of the complete rocket.

A representative fuze from each class is discussed in the following paragraphs. The fuzes currently in use and their primary application are listed in table 2-3. For more detailed information on fuzes, refer to Airborne Rockets, NAVAIR 11-85-5.

Fuzes

Rocket fuzes are primarily classified by their location in the warhead; for example, nose fuze or base fuze. They are further classified by mode of operation, such as impact-firing, mechanical-time, acceleration and deceleration, or proximity. All fuzes contain safety/arming devices to prevent detonation during
