CHAPTER Il, SECTION 3 winds or overpressure. This was accomplished through the use of bolts connecting the tower wheel trucks to metal plates embedded in the foundation. Two pairs of rails were laid between the firing and auxiliary pad for moving the tower. The tracks were laid on wood ties and gravel ballast. Two concrete revetments for trailers were located about 125 feet from the firing pad and about 90° apart. They were 14 feet high with one 25 feet long and the other 30 feet long. Each had 12-foot-long wing walls and about 5 feet of earth fill in front. Each of two small concrete revetments were located in diagonally opposite corners of the firing pad area about 120 feet from the pad centerline. They were 12 feet long, 64% feet high, with 10-foot-long wing walls and were to be used to house fire protection water nozzles. The nozzles were subsequently relocated to the 25-foot-long trailer revetment to furnish water to the center of the firing pad in the event of a fire. Two salt water wells and diesel-driven pumps provided the water. Concrete cable trenches were located between the firing pad and 30-foot-long revetment, between the two revetments, and from the first trench to the diagonally opposite corner of the pad. These trenches were 2 feet wide, 114 feet deep, and were provided with steel cover plates. Close to the firing pad a timber personnel shelter, 24x26x8 feet high, was placed. The shelter was skid-mounted and contained receptacles and lights circuited to a portable plug, which connected to a power receptacle on the pad. A skid-mounted portable wood shelter was provided for use as weather protection during a possible horizontal check-out of the missile. The shelter was 16x35x17 feet high with open ends and plywood roof and sides. The entire firing pad area and the railway between it and the auxiliary pad were illuminated by floodlights. Receptacles were provided throughout the pad area for trailers and miscellaneous equipment. With the relocation of the ABMA Program, this facility was dismantled and moved to the new site at Johnston Island.

The forward wall was 14 inches thick. The walls were supported on spread footings. There were four rooms within the building, two instrument rooms, a stand- by room, and an equipment room. There were 1x14-foot cable trenches with steel cover plates along the interior perimeter of both instrument rooms and along two walls in the stand-by room and one wall in the equipment room. A concrete cable duct extended out of the building through the fill from the interior cable trenches. Cables her (Neg. No. W-V-175-1) Figure No. 2-66. Station 6002 — How — 48% Complete. Page 127
