---------------WARNING ---------------HIGH VOLTAGE is used in the operation of this equipment. DEATH ON CONTACT may result if personnel fail to observe safety precautions

Never work on electronic equipment unless there is another person nearby who is familiar with the operation and hazards of the equipment and who is competent in administering first aid. When the technician is aided by operators, he must warn them about dangerous areas. Be careful not to contact high-voltage connections of 115 volt ac input connections when installing or operating this equipment. Whenever the nature of the operation permits, keep one hand away from the equipment to reduce the hazard of current flowing through vital organs of the body. Warning: Do not be misled by the term `low voltage." Potentials as low as 50 volts may cause death under adverse conditions. For Artificial Respiration, refer to FM 21-11. ---------------WARNING ---------------EXPLOSIVES The STINGER Air Defense Guided Missile System contains explosives. All applicable safety regulations will be strictly enforced. Explosive components containing electrical wiring must be protected at all times from stray voltages or induced electrical currents.

Handling operations should not be performed during electrical storms. Explosives are contained in the weapon-round, missile-round, and battery coolant unit. TOXIC MATERIALS BASIC STINGER ONLY Do not touch the vicinity of the missile seekerhead dome if it shatters, as mercury thallium liquid may be released. This material is toxic to unprotected skin. Avoid all contact with the released material unless protective equipment is being worn such as a respirator, impervious protective gloves, and chemical goggles. If the skin or eyes are exposed to the spilled material, immediately flush with copious quantities of water. Any person exposed to the released material should be promptly referred to a physician. BASIC STINGER, POST AND RMP The missile exhaust contains amounts of HC1 gas which may cause eye and/or throat irritation when personnel are exposed. To prevent any irritation or exposure to potentially harrnful concentrations of HC1 in the exhaust plume, the gunner and assistant must hold their breaths until the trigger is released and move away from the exhaust plume, if necessary, before breathing again.

EXPENDABLE SUPPLIES AND MATERIALS LIST TM 9-1425-429-12 HOW TO USE THIS MANUAL The manual is divided into two parts. Part one provides you, the gunner, with operating instruction improvements resulting from the addition of UV detection and the reprogrammable module, normal maintenance requirements for the weapon round, field handling trainer, and IPF interrogator. Part two provides instructions for operating and servicing the IFF programmer/battery charger. Portions of this manual which apply only to the Stinger-POST will be preceded by (POST), portions which apply only to the Stinger with the reprogrammable microprocessor will be preceded by (RMP). PART ONE TEAM PROCEDURES CHAPTER 1 INTRODUCTION Section I. GENERAL 1-1. Purpose and Scope Part one of this manual is for your use in operating and maintaining the STINGER Intercept-Aerial Guided Missile System (weapon-round partial plus grip stock, hereafter weapon-round), Trainer, Handling, Guided Missile Launcher: M60 (field handling trainer), and Interrogator Set AN/PPX-3A and AN/PPX-3B (IFF interrogator). 1-1.1 Differences Between Models Differences between models are contained in the following paragraphs: a. Missile Rounds (1) The Stinger-POST (Passive Optical Seeker Technique) has a different front window than the basic Stinger. The front window is

transparent, which permits IR and UV detections. In addition, the Guidance Assembly has been improved to allow the gunner to track positive contrast IR and/or negative contrast Uv radiation, to provide greater background discrimination than the basic Stinger. (2) The Stinger RMP (Reprogrammable Microprocessor) retains all the Stinger-POST improvements and also has additional improvements to the guidance system. These improvements enable the weapon to reject more complex IRCM and provide greater black discrimination than the basic Stinger or Stinger POST. b. Weapon Rounds In addition to the improvements to the missile round, an electronic housing has been added to the separable gripstock, to accommodate installation of an RMP module. The RMP module allows reprogramming of missile software programs for enhancing performance in different threat environments. c. Gripstocks Gripstocks without the RMP module may be used with the basic and POST missiles. RMP missiles without the RMP module will default and function as if they were POST missiles. Gripstocks with the RMP module may be used with all STINGER missiles. d. Interrogators The basic difference between the AN/PPX-3A and the AN/PPX-3B is the addition of an electronic day indicator activating switch and needed circuits on the AN/PPX-3B. For detailed information, refer to TM 11-5895-1194-24. e. Training Set, Guided Missile System M134, M158, M160 For information on the training sets and the caotuve flight trainer refer to TM 9-6920-429-12 f. Field Handling Trainers M6O, XM148 The XM 148 trainer uses the same dummy launch tube as the M60, without the gripstock and IFF interrogator. The M60 trainer must have the gas insert assembly removed prior to use with SVML. Refer to para. 2-10 for instructions for removal of the gas insert assembly. TM 9-1425-429-12 1-2. Security Requirements a. The weapon round, missile round, gripstock with the RMP

module installed, and IFF interrogator are classified CONFIDENTIAL for storage, handling, and shipping. During shipment,the weapon round is split into two components,the weapon round partial and the gripstock. After arrival at an ammunition supply point (ASP) or military unit,the gripstock may be placed in the weaponround partial container. If the gripstock is placed in the weapon round partial container, write the NSN number of the gripstock above the existing NSN on the container, using china marker (Item 19, App. E).Be security unconscious when any of these items become your responsibility. Be sure that they never leave your sight. When you are not using the weapon or interrogator, be sure they are protected against unauthorized access, theft and sabotage. b. In the event ofloss or theft of a weapon round, weapon-round partial, missile round, gripstock with RMP installed or IFF interrogator, notify your local commander immediately. The commander must take action as prescribed in AR 210-10, AR 310-84, and AR 380-5 and must insure that the appropriate military and civilian law enforcement agencies are notified promptly. c. When the weapon is fired, and the missile launch and flight motors function normally, classified components should be destroyed by warhead detonation or ground impact. Whenever a missile malfunctions, or if there is reason to believe that classified components may not be destroyed, attempt to locate and destroy it as prescribed in para.6-2 of this manual 1-3.

You must have the weapon round and BCU to have an operational weapon. To have IFF capability, you must connect the IFF interrogator set to the weapon round using the interconnecting cable. Descriptions for the above items as we11 as descriptions for the shipping and storage container, transport harness, and field handling trainers are provided in paras. 1-6 through 1-7.

Figure 1-1. Stinger weapon-round and IFF interrogator 1-6. Weapon-Round Description a. Missile-Round (Figure 1-2). The missile-round consists of two major parts: the missile and launch tube assembly. (1) The missile is housed in the launch tube. The major components that make up the missile are shown in Figure 1-2. The missile uses infrared (heat-sensitive) homing. It is ejected from the launch tube by the launch motor and propelled in flight by the ffight motor. The launch motor is expended and separated from the flight motor before the missile is out of the launch tube. The expended launch motor drops from the missile outside the launch tube at a safe distance from you. Also, at separation, a lanyard attached to the launch motor pulls the shorting plug from the flight motor ignition circuit. After the missile coasts a safe distance from you, the flight motor fires. The missile will selfdestruct after a total of 17 seconds of in-flight time shorting plug from the flight motor ignition circuit. After the missile coasts a safe distance from you, the flight motor fires. The missile will self lestruct after a total of 17 seconds of in-flight time.

Figure 1-2. Missile-round (2) The launch tube is made of molded fiberglass with an lR window in one end and a blowout disc in the other to seal the missile in the tube from moisture and foreign matter. A desiccant cartridge/humidity indicator unit on the launch tube indicates whether moisture has entered the tube. (3) The sight assembly is attached to the launch tube. You use this to aim the weapon, to estimate the target range, to superelevate to the proper angle, and to correctly lead your target. Two acquisition indicators mounted on the sight assembly tell you IFF status and whether the missile is "locked on" the target. One of these indicators is a tiny speaker that produces various tones. The other indicator vibrates against your cheekbone, transmitting sound vibrations through the bones to the ear. Also attached to the sight assembly is a clear plastic eyeshield to protect your left eye when the weapon-round is fired. b. Separable Gripstock (Fig. 1-3). The separable gripstock attaches to the underside of the missile-round with a latch mechanism. After firing a missile, the separable gripstock will be removed from the launch tube assembly for re-use. The separable gripstock consists of the gripstock assembly and the IFF antenna assembly. The gripstock assembly contains the safety and actuator device, uncaging switch, firing trigger, IFF interrogator switch and IFF interrogator connector, and BCU receptacle. The IFF antenna assembly folds on the side of the gripstock assembly when not in use. When it is unfolded and the interrogator is connected to the weapon-round, aircraft can be interrogated. c. Battery Coolant Unit (BCU). The BCU screws into the battery receptacle on the underside of the separable gripstock. lt contains a thermal battety and pressurized argon gas coolant. When you operate the safety and actuator device, the BCU then must be removed within 3 minutes to prevent damage to the gripstock.

Figure 1-3 Separable gripstock ---------------WARNING ---------------After it is activated, the BCU becomes very hot. Handle only by the insulated cap when removing. After removal high pressure argon gas may still be flowing from the needle. Keep needle at least 1 inch away from skin.

CAUTION ---------------The BCU should not be placed in the separable gripstock prior to mating with the missile round. To prevent coolant system contamination, the BCU must be discarded following removal from the gripstock assembly; this is necessary even if the BCU was never activated while installed in the gripstock. 1-6.1. M60 Field Handling Trainer (FHT) Description The FHT (figure 1-3.1) is a dummy round which simulates the operation of a weapon round. It has no actual electronics but has all the external features of the tactical launch tube, gripstock, and sight assembly. It provides the gunner with realistic training, while allowing him to make errors without damage to more sensitive equipment. The FHT consists of a ballasted launch tube assembly, dummy separable gripstock, dummy BCU, and dummy IFF interrogator. The trainer provides practice in the basic skills of weapon handling to include transportation, procedures, reaction times, sighting, and ranging. 1-6.2. Field Handling Trainer XM148 Description The XM 148 FHT (figure 1-3. 1) is also a dummy round, but has no gripstock, IFF interrogator, or BCUs.It is used to train crews in the handling of STINGER weapon rounds as part of the ATAS launch system. 1-7. IFF Interrogator Description a. General. The IFF interrogator (figure 1-4), when connected to the weapon round,helps you determine whether the sighted aircraft is friendly or unknown. The interrogator is a battery-powered unit that attaches to your web belt, using the clip on the side of the case. The interrogator connects to the weapon round using the interrogator cable assembly. The cable assembly connector end has a clamping device attached to the connector cap by a lanyard cable. The clamp holds the interconnecting cable connector on the operator's flak jacket allowing him to quickly remove it from the protective cap and connect it to the gripstock assembly. b. Functional Diagram (1) The IFF interrogator operates in one of three programs; mode 3 (M3) only or mode 4 (M4) only, or M4/M3 automatic.

Figure 1-3.1. Field handling Trainers

Figure 1-4. Clamp assembly and interrogator assembly. (2) When the tactical situations require the use of either M4 or automatic M4/M3 coding, you must return the IFF interrogator to section headquarters for reprogramming at 1east every four days. When reprogrammed at headquarters the reprogramming date is recorded on the top of the IFF Interrogator. In addition to the written date of programming, the AN/PPX-3B wi11 read out the mode 4 day of code when the READ switch is pressed. The M4 and M4/M3 programs selected for the IFF interrogator operate for 4 days. After 4 days the IFF interrogator automatically switches to the M3 only mode and remains in that mode until it is reprogrammed. (3) Let's assume that the M4/M3 program has been entered into your IFF interrogator and you want to challenge an aircraft. The operation starts when you press the IFF interrogate switch on the gripstock and lasts about 2 seconds. During this period, numerous interrogations are transmitted by the antenna. If the correct replies for mode 4 are received, you get a half second "beep" then a half second later you get another "beep". This mode 4 tone positively identifies a friendly aircraft. If correct mode 4 replies are not received, the interrogator automatically switches to mode 3 and interrogates again. If the correct replies are received you will get a single one and a half second "beeeeeeep". If you don't get a reply you will hear a string of short "beeps" telling you that the target identity is unknown. Of course, if your interrogator had the M4 only program inserted, you would either get the mode 4 friendly tone - two "beeps" or the unknown tone - a string of "beeps". If no tone is heard when you press the IFF interrogate switch, your IFF system is defective. 1-8. Weapon-Round Principles of Operation. Figure 1-5 is a sequential illustration describing the operation of the weapon-round using the IFF interrogator. Some of the steps in this series can be performed at the same time. Also, the exact sequence of some steps may vary depending on different tactical situations.

Weapon-Round Containers.During shipment the weapon round is shipped in two containers, the weapon-round partial container and the Irripstock container. Following arrival at an ammunition supply point or military unit the gripstock may be placed in the weaponround partial container. Write the NSN of the gripstock above the existing NSN on the container, using chinamarker (Item 19, App. E). (1) Weapon-Round Partial Container/Ready Rack. This container provides protection for one weapon round and up to five BCUs during shipping and storage. The container has handles for two-man carry, four lid latches, a humidity indicator, and a pressure relief valve. The top corners of the container are marked with 2V-inch yellow squares. (2) Gripstock Container. Gripstocks are packed in Class A containers in accordance with the packaging data sheet. b. Missile-Round Container. This container provides protection for one missile round and up to three BCUs during shipping and storage. c. IFF Interrogator Container. This shipping and storage container provides protection for one IFF interrogator, interrogator battery, and interconnecting cable. d. FHT Shipping Container. The shipping containers for the FHT M6O and XM 148 are similar in appearance to the weapon.round container. The top corners are marked with 2 1/2-inch bronze-colored squares and the word dummy is marked in two places. It provides protection for one field handling trainer during shipping and storage. 1-10. Weapon-Round Container/Ready Rack and Transport Harness Description The transport harness secures the containers to the M4 16 trailer in a manner that permits fast access to the weapon-rounds. Figure 1-7 shows how the M416 trailer is used to transport four weapon rounds and two missile rounds. The four weapon-round containers are located along the sides of the trailer

(two stacked on each side)with latches facing outward. The two missile-round containers are located in the center. The top two weapon-round containers are converted to ready racks by releasing the latches to make the two weapon rounds available.

Safety and Handling Precautions ---------------WARNINGS ---------------Before inserting the BCU, carefully inspect the entire weapon-round. To ensure that the seeker head can properly see the target, the blowout disc can shatter evenly, and over-pressures within the 1aunch tube are prevented, remove any caked dirt, mud, or ice from the IR window and the rear end of the launch tube. In addition, check that the desiccant cartridge/humidity indicator is securely installed. Prior to insertion of the BCU into the gripstock and as a safeguard against inadvertent missile firing or unintentiona1 battery discharge occurring when inserting the BCU into the gripstock, be sure that the firing trigger, uncaging switch, and the safety and actuator device operate freely and are in the unpressed position. ---------------WARNING ---------------Weapons in containers that fall more than 84 inches are considered unsafe and should only be handled by qualified personnel. NOTE Weapons in containers that fall 3 feet or less and weapons not in containers that fall 2 feet or less are considered functionally operable. Weapons that fa11 from a distance in excess of 3 feet (2 feet if not in a container) but less the 7 feet must be turned in to the depot for test and evaluation. FIRING CLEARANCE REQUIREMENTS For you to be free to fire safely in any direction, the area around must be clear of any obstructions or personnel for a distance of 45 meters (150 feet).

All personnel within 125 meters (400 feet) must wear hearing protection devices. To minimize the possibility of injury from flying debris do not fire with the launcher elevated more than 65 degrees or 1ess than 10 degrees or with the aft end of the launch tube closer than 30 inches to the ground. HIGH PRESSURE/HIGH TEMPERATURE Following activation, surface temperature of the BCU can rise to 400 degrees Fahrenheit within ten minutes. The heat so generated can both burn bare hands and cause permanent deformation of the gripstock BCU receptacle. To prevent such casualties, remove the BCU from the gripstock within three minutes following activation and discard.(In a training environment allow a 30-minute cool-down period before handling the discarded BCU.) Heat-caused casualties, however,are not the only consideration for concern when removing the BCU. If the BCU is still discharging high pressure gas when it is removed from the gripstock, do not allow the top to come close to, or to point at, your body. The possibility of the high-pressure gas discharge puncturing your skin is a major safety consideration. In addition, the gas discharge can cause burns to your body even if not close enough to puncture the skin. TOXIC MATERIALS BASIC STINGER ONLY Do not touch the vicinity of the missile seekerhead dome if it shatters, as mercury thallium liquid may be released. This material is toxic to unprotected skin. Avoid all contact with the released material unless protective equipment is being worn such as a respirator, impervious protective gloves, and chemical goggles. If the skin or eyes are exposed to the spilled material, immediately flush with copious quantities of water. Any person.exposed to the released material should be promptly referred to a physician. BASIC STINGER, POST AND RMP The missile exhaust contains amounts of HCI gas which may cause eye and/or throat irritation when personnel are exposed. To prevent any irritation or exposure to potentially harmful concentrations of HCI in the exhaust plume, the gunner and assistant must hold their breaths until the trigger is released and move away from the exhaust plume, if necessary, before breathing again. SAFETY EQUIPMENT In addition to your helmet,you must use the plastic eyeshield installed on the weapon-round sight, and earplugs. The earplugs are in each weapon and missile-round shipping and storage container.

For target acquisition you must have the target centered in the sight range ring. There are four major factors that limit range: target speed, IR/UV signal strength, the time it takes the missile to reach flight speed, and the time required for a target intercept. The sight range is used as an aid to determine when a target can be engaged. Proccdures for using the range ring are found in (SNF) FM 44-1A. If the target is too close for the missile to be launched effectively, you should keep tracking the target until it passes beyond minimum range before firing. In order to assure proper gyro performance and seeker head cooling before the missile is fired, the weapon-round must be activated at least 3 to 5 seconds before squeezing the firing trigger. 2-4. Weapon-Round Operating Instructions The following illustration sequence demonstrates the procedure used to prepare, aim and fire the weapon round. CAUTION When handling the weapon-round, be careful not to damage the launch motor igniter leads running lengthwise on the outside of the launch tube. Keep the front cover in place until you make the weaponround ready for use. Always place the weapon-round on its side if you lay it down, never stand it on its end. NOTE Remove the styrofoam cube behind the retaining clip of the bone vibrator prior to shouldering the weapon. Replace if weapon is not fired.

2-5. Hangfires, Misfires and Duds ---------------WARNING ---------------For a hangfire, misfire, or dud missile, personnel should evacuate the area around the missile for a distance of 1200 feet. The missile must not be approached for 3 hours. Death or injury may result. a. Hangfires and Misfires. A hangfire is a delay in functioning of the explosive components caused by electronic malfunction, loose electrical connections, faulty explosive devices, etc. The delay may be from a split second to several minutes. A misfire is a complete failure to fire, but if the missile fails to fire, always assume it is a hangfire and perform the following steps: (1) Continue to track the target for 3 more seconds, keeping both the firing trigger and uncaging switch pressed. ---------------WARNING ---------------BCU gets extremely hot when activated. Grasp it only by heat-insulated cap when removing it. Do not point top of BCU toward skin because high pressure gas may still be escaping. Do not handle BCU for 30 minutes after removal. (2) If the missile has not ejected after 5 seconds. release the firing trigger and gyro uncaging switch; then immediately remove IFF cable and BCU. Carefully place the weapen-round on a stand or on the ground, keeping both ends of the launcher pointed away from personnel with the forward end slightly elevated (approximately 20 degrees). Leave the area immediately, do not cross in front of or behind the weapon. Hazardous conditon exists for 3

hours after trigger pull. (3) Mark the location of the defective weapon-round. All personnel seek shelter and immediately notify the supporting Explosive Ordnance Disposal (EOD) unit. Weapon should not be approached for at least 3 hours. Move to a safe position and keep the weapon round under surveillance. Since the weapon-round is classified, it must not be left unattended. b. Duds. A dud missile situation occurs when the flight motor does not fire after the missile has ejected from the launch tube.

Figure 3-2 Field Handling Trainer XM148 replacement parts PART TWO SECTION HEADQUARTERS PROCEDURES CHAPTER 4 OPERATING INSTRUCTIONS FOR IFF PROGRAMMER/BATTERY CHARGER Section I. GENERAL 4-1. Purpose and Scope This section contains operating and maintenance instructions for the Programmer, Interrogator Set AN/USX1 and AN/GS (IFF programmer/battery charger) and Computer KIR-IA/TSEC (power supply mode1 ZAC A/1) with Code Key KIK- 18/TSEC 4-2.Equipment Description. a. In this chapter the programmer/battery charger will be identified as either the programmer or battery charger- depending upon which function is being described. The programmer is used to program the IFF interrogator and the battery charger is used to charge up to six IFF interrogator batteries. After a charged battery is installed, the IFF interrogator can be programmed for 4 days of operation in either mode 4 only or mode 4 and mode 3 (automatic). b. With the exception of the interrogator cable assembly, all cables required for interconnection are stored in the upper compartment of the programmer/battery charger.

c. The computer supplies only mode 4 data, selected by the code key through the programmer to the interrogator. Mode 3 is built into the interrogator, but it can also be programselected by the function switch on the programmer. This switch selects the programming operation (M4 or M4/M3) made available to the interrogator. In the M4 position, the interrogator is programmed to operate in mode 4 only. In the M4/M3 position, the interrogator is programmed to operate in mode 4 and then switch automatically to mode 3 if there is no mode 4 reply or if mode reply is improper. For either program, a 4-day countdown period is started in the interrogator by the programmer. d. Another function of the programmer is to self-check the interrogator. This check makes sure that the interrogator is operational. e. The battery charger can charge up to six batteries at one time. During the charging operation, each battery being charged can be checked to be sure that the batteries are accepting the charge. It takes a minimum of 4 hours to fully charge the batteries. Additional charge time on the charger will not damage the batteries. Section II. PROGRAMMER/BATTERY CHARGER CONTROLS AND INDICATORS4-3. Functions The controls, indicators, and connectors for the programmer/battery charger are illustrated in figure 4-1. Their functions are listed in table 4-1.
