The S&A device attaches to the target detector and is located between the TD section and the warhead section. The S&A device contains an interrupted firing train that is aligned by an acceleration arming device. It contains the necessary high explosives, switches, and circuits to initiate detonation of the warhead. The WDU-17/B warhead (used in the AIM-9L configuration) is an annular blast fragmentation warhead that consists of a case assembly, two booster plates, an initiator, high explosive, and fragmentation rods. The explosive output from the S&A device is transferred through the initiator to the booster plates. The initiation is then transferred through the explosive-loaded channels of the booster plates to the booster pellets at each end of the warhead. Detonation of the booster pellets sets off the high explosive, causing warhead detonation. The WDU-9A/B warhead (used in the ATM-9L-1 configuration) is mechanically interchangeable with the WDU-17/B tactical warhead The WDU-9A/B contains a smoke-flash mix with CH-6 booster to provide visual observation of the missile/target hit. The Mk 36 Mod 7 rocket motor uses a single-grain propellant. A nonpropulsive head closure, located on the forward end of the motor tube, blows out if the motor is accidentally ignited without the warhead installed, making the motor nonpropulsive (a fire hazard vice a missile hazard). The Mk 36 Mod 8 rocket motor is basically identical to the Mod 7 motor except that the Mod 8 motor is equipped with a safe-arm ignition assembly. The purpose of this assembly is to prevent accidental or inadvertent rocket motor ignition. The safe-arm ignition assembly must be manually rotated to the armed position before flight. This is accomplished by the use of a hex-head T-handle. Four Mk 1 Mod 0 or Mod 1 wings are attached to the aft end of the motor tube. They provide aerodynamic lift and stability during flight. Each wing has a rolleron assembly that provides pitch, yaw, and roll stabilization during free flight. When the missile is fired, the rolleron is uncaged by acceleration and is free to move through its longitudinal axis during flight. The rolleron wheel is designed so that the passing airstream causes it to spin at a very high speed, thus acting as a gyroscope, which helps to stabilize the missile and reduce roll during flight. For further information about the AIM-9L/M and ATM-9L-1 Sidewinder guided missile, you should refer to the Sidewinders Guided Missile AIM-9L and Training Missile, NAVAIR 01-AIM9-2. Advanced Medium Range Air-to-Air Missile (AMRAAM) The AMRAAM is an all-weather missile (fig. 3-10). Aircraft currently scheduled to carry the missile are the Figure 3-10.—AIM-120 AMRAAM guided missile 3-13
