11–11. AGM–114 A/F and AGM–114 K/N HELLFIRE missile weapon danger zones/surface danger zones a. Direct fire/indirect fire HELLFIRE missile weapon danger zones/surface danger zones. The direct fire and indirect fire WDZs/SDZs support the AGM–114 A/F and AGM–114 K/N HELLFIRE for firing at fixed targets for both Army and Marine Corps RW aircraft. These WDZs/SDZs include the effects of HE warhead functioning at the edge of the impact area. However, an additional 216 m must be added to Areas A and B to allow for the larger warhead for the AGM–114 M/N. Because of the unique shape and size of the WDZs/SDZs, the actual scaled (1:50,000) safety fans must be requested from the respective ACOM, ASCC, and DRU safety office (Army). In this chapter, the AGM–114F includes the AGM–114FA model. b. When firing in a lock-on-after-launch mode, a 30 degree angle will be used for all AGM–114 WDZs/SDZs. (1) Direct-fire WDZ/SDZ (see fig 11–4). This WDZ/SDZ will be used for AGM–114 A/F missiles and, for the Marine Corps, only the AGM–114 K/N missile with the following launch modes and conditions: (a) Aircraft configured in accordance with latest SOUM. (b) Lock-on before launch with remote designation. (c) Lock-on after launch (direct-launch mode) with remote designation. (d) Lock-on after launch (direct-launch mode) with autonomous designation and proper designation delay: 1. For AGM–114A missiles, use a minimum delay of 3 seconds and a maximum delay of 10 seconds. 2. For AGM–114B/F missiles, use a minimum delay of 3 seconds and a maximum delay of 5 seconds. 3. For designation delay as calculated for range to target after missile separation, always add 1 second to the designation (separation) delay times when counting from trigger pull. (2) Indirect-fire WDZ/SDZ (see fig 11–5). This WDZ/SDZ will be used for AGM–114 A/F and AGM–114 K/N HELLFIRE missiles with the following launch modes and conditions: (a) This WDZ/SDZ will be used with any HELLFIRE missile operational mode not described in paragraph 11–11b(1) above and with remote or autonomous designation. For the Army RW aircraft, firings of the AGM–114 K/N are restricted from utilizing direct-fire WDZ/SDZ. The HELLFIRE operational mode launch parameters and perform- ance envelopes are described in FM 3–04.140 and the latest SOUM. (b) To minimize backscatter for Lock-On-Before-Launch (LOBL) autonomous engagements use the following target offsets: 1. 3 to 5 degree target offset. 2. Always offset the missile launch angle toward the side of the launch platform on which the missile resides to reduce the chance of interference with autonomous tracking. 3. No offset is necessary when using remote designation. c. Expanded direct fire/expanded indirect fire weapon danger zones/surface danger zones - Army rotary wing aircraft. Due to excessive missile roll rates induced by interactions between specific Army RW aircraft and their associated launchers, two additional WDZs/SDZs have been established to compensate for possible missile error (roll tip-off error). The expanded direct (AGM–114 A/F) and expanded indirect (AGM–114 A/F and K/N) WDZs/SDZs (see figs 11–6 and 11–7) are required for all Army RW aircraft. However, based on specific aircraft launcher configurations and firing modes, certain Army RW aircraft may be allowed to use the standard direct/indirect WDZs/SDZs as indicated in figures 11–4 and 11–5. Refer to table 11–3 and the latest Army HELLFIRE SOUM to determine which aircraft and under which configurations and firing modes are acceptable for firing under the standard direct/indirect WDZs/SDZs. d. Altitude restrictions. HELLFIRE WDZs/SDZs as depicted in figures 11–4, 11–5, 11–6, and 11–7 are based on a maximum launch altitude of 300 ft AGL. If firing above 300 ft AGL then the ’Radial’ extent of the WDZ/SDZ is increased by 1 m per additional foot of launch altitude. Minimum clearance airspace will be 20,000ft above launch altitude. Refer to the latest SOUM associated with HELLFIRE delivery to ensure appropriate parameters are met. e. Area F. An area to the rear of the launch point 30 m wide (15 m to each side of the launcher) and 50 m long when aircraft are at or below 300ft AGL. Hazards are launch motor blast, hazardous noise levels, overpressure, and debris. Serious casualties or fatalities may occur to personnel occupying Area F; therefore, occupation of it is not authorized. 11–12. AGM–114 P/P+/R HELLFIRE missile AGM–114 P/P+/R WDZs. All WDZs/SDZs will be developed using the RMTK WDZ tool. These missiles are authorized for high altitude firings in order to support additional platforms such as UAS and C–130 Hercules aircraft in accordance with the latest HELLFIRE SOUM. 11–13. HELLFIRE missile maximum altitude The maximum altitude for HELLFIRE missile firing is 20,000 ft (6,096 m) above launch point. 145 DA PAM 385–63 • 16 April 2014
