JOHNSTON ATOLL SCIENTIFIC 01005 Page 2 Large Launch Pad Concrete pads are designed for a loading of 70,000 pounds with a vehicle in place. Launchers will be attached to pads by eighteen 1 1/2inch bolts located on a 6-ft. 6-in. bolt circle. Maximum overturning moment of these single boom launchers will be approximately 600, 000 ft. -pounds. Medium Launch Pads Concrete pads are designed for a loading of 40,000 pounds with a vehicle in place. Launchers will be attached to pads by sixteen 1 1/2-in. bolts located ona 4-ft. 6 1/2-in. bolts circle. Maximum overturning moment of these single boom launchers will be approximately 500, 000 ft. -pounds. Small Launch Pads Concrete pads are designed for a loading of 25,000 pounds with a vehicle in place. Launchers will be attached to pads by six 1 1/2-in. bolts located on a 3-ft. 6-in. boit circle. Maximum overturning moment of these double boom launchers will be approximately 100,000 ft. -pounds. Other Requirements All launch pads are 30-ft. diameter inscribed octagons. The south firing pads will be bounded by a 50-ft. wide soil cement strip on the north side. An additional 25-ft. compacted area will be provided on all other sides of the pads. An adjacent dry, 6 x 6 x 3-ft. concrete pit equipped with a 3/8-in., blast proof, steel plate, hinged door will be provided for each pad. Portable area lighting will be provided to allow a safety check of the launch pad area prior tonighttimelaunches. Chemical latrines will be provided in the area of the launchers. Power required will be 3.7 kw of 208 volt, 60 cycle, 3 phase per launcher to operate a5 HP motor. The control system will utilize 110 volts, DC and the firing system will utilize 110 volt, 60 cycle, 3 phase power. Anominal110 volt, 60 cycle, single phase auxiliary power circuit will also be installed at each launcher pedestal to operate such items as soldering irons, trouble shooting lights, etc. Control cabling requirements are described in F&S No. 04019, 1-9 qn VOLTI Ape396
