the pads was dooe several weeks in acwance of launcher erection to perait the concrete to obtain sufficient streagth. Locations of launcher stations are given in Table 6.3. Preparation of the Launcners included necessary preassexbly, erection, and prelininary aligement. For preasseably and erection purposes, a crew of five men took approximately two days per launcher. In addition to standard hand tools, a crane of approximately 40-foot boom length and 10,000-pound capacity, and a second, smaller crane or boos truck were required. after erec- tion was completed, several hours were required to set aziouth and elevation angles. Preparation of the vehicles for firing, after instrumentation has been checked out, consists of assexblying major subassemblies, described in Section 8.2.1, into the ready vehicle, loading onto the launcher, final checkout, aod final Launcher alignment. a vehicle for firing. A four-man crew requires one to tw. days to prepare During the assembly period, suitable protection froa vain aod blewizg sand and dusc is required. After the vehicles are assembled and Icaded on the launchers, they must remain for extended periods at temperatures up to l2O degrees Fahrenheit with no protection cther than waterproof tape over open joinrs and ports. Tape must be removed before firing. Launchers and vehicles are painted white to minimize radiation teaperature effects and as a protection against enviroment. Final preparation for firing consists of removal of protective tape, manual arming of the rocket engines, and electrical arming of launching circuits. This requires only wimites, and final preparation time may be extended to several bours, provided elevation and/or azi=uth adjustments are required. 6.3 PERFORMANCE OF RF ATTENUATION AND CHAFF ROCKETS A rocket system capable of carrying either chaff or a transmitter to high alrirtudes was developed for use in conjunction with the Teak shot. pose of the chaff system was to measure winds at burst altitude. The purThe tranos- aitter configuration, designated as Hi-Lo, was designed to measure attenuation of radiofrequeacy waves caused by fonization accoupanyicg the burst. plete series of rounds was available fer use as a backup on Teak. A ¢coa- ‘shen these were not required foc the intended purpose, a decision was sade in the field to expend thea on Orange. The system was flexible enough to adapt to Orange J). oOo
