7–2. FGM–148 Javelin guided missile The Javelin is a shoulder-launched, man-portable, anti-armor weapon system. It fires a passive-imaging infrared (IR) missile with a lock-on before launch guidance system. The Javelin Block 1 antitank missile has extended range capability, enhanced software, and an improved warhead. a. Firing conditions. (1) Before firing any Javelin missile, the entire SDZ will be cleared of non-participating personnel. Only those participating personnel specified in appropriate FMs and TMs will be permitted in any part of the SDZ. (2) Javelin missile firings will be accomplished within predetermined boundaries. Installation RMAs (Army), RCOs (Marine Corps) will ensure that an adequate SDZ exists along the MTL from each anticipated launch position within the predetermined boundaries. (3) See applicable FMs and TMs for preparation and firing operations. (4) Personnel will neither stand nor permit any part of their body to be directly behind or in front of the Javelin launcher. (5) Personnel engaged in firing or supervising Javelin missile training will wear a minimum of PPE Level 1. Refer to table 2–2 (Marine Corps) for further guidance. (6) Personnel within 500 m of the target should be in a location protected from debris coming from the target. b. Surface danger zone construction for the Javelin antitank missile. (1) The SDZ for firing Javelin missile at a fixed target is illustrated in figure 7–5. This figure represents probability of missile fly-out, debris, fragmentation, and so forth, escaping the SDZ boundaries; 1 in 1,000,000 (10 -6 ) (21 degrees), 100,000 (10 -5 ) (17 degrees), and 10,000 (10 -4 ) (13 degrees). The dimensions found in figure 7–5 using 21 degrees is the standard Javelin missile SDZ. Javelin missile SDZ criteria are in table 7–2. (2) The SDZ for Javelin Block 1 missile is in figure 7–6. Javelin Block 1 missile SDZ criteria are in table 7–3. Javelin Block 1 SDZ variable criteria are in table 7–4. (3) Area A is 500 m wide for the HE warhead equipped rounds and 200 m for inert warhead rounds from the launcher to a point 1,000 m downrange for Javelin missiles and 1,327 m for Javelin Block 1 missiles. At these distances, the flight motor is fully exhausted. The remaining downrange portion of Area A tapers down to a 200 m width for HE warhead rounds and 100 m for inert warhead rounds at Distance X. Area A will contain missile and warhead debris from impacts on the boundary selected fly out line/trajectory limit and portions of the missile that remain attached to the propulsion section which may continue to be propelled until flight motor burnout. (4) Area B will contain the debris associated with a missile landing at the uprange edge of the area. Area B is 500 m for both HE and inert warheads. (5) Area F (see fig 7–7) consists of the primary danger area and caution areas 1, 2, and 3. (a) The primary danger area is a 60 degree angle (30 degree either side of the rearward extension of the MTL) with the apex at the aft end of the missile launch motor. This area has a 25 m radius. Additionally, the primary danger area is extended forward to the firing line from a distance of 1 to 5 m left and right of the MTL (see fig 7–8). (b) Caution Area 1 is an extension of the 25 m primary danger area arc forward to the firing line on each side of the launcher. Serious hearing impairment or damage from frequent exposure could occur to personnel in this area during firings. Personnel in this area must wear approved hearing protection devices. (c) Caution Area 2 is an extension to the rear of the primary danger area, 10 m beyond the primary danger area. (d) Caution Area 3 is an extension to the rear of the primary danger area within the 60 degree sector with a 100 m radius. This area is affected by the activation of the flight motor pressure relief system. Personnel located in this area will wear eye protection. (6) The use of an SDZ with a missile fly out probability of greater than 10 -6 (such as, 10 -5 , or 10 -4 ) requires an approved deviation in accordance with AR 385–63/MCO 3570.1C and chapter 1 of this pamphlet.
