MSR Complex Samples

	7348 (M) (L)	7334 (M) (L)	1021 (M)
	7348: MSCB and power plant under construction (HAER). 7334: MSCB turret, northeast face (HAER). At the lower right is open blast door #BD2. This emergency escape, at stair no. 12, is NEMP/RFI-shielded and 16" thick. 1021: Installation of an antenna element (delay line) (Ves Fulp). Each of the four antenna faces contained 5,000 of these elements. Under computer control, the delay line altered the phase of the element's radiated energy in order to steer the antenna beam. The outside of each element was covered by a beryllia window.
	0065 (M) (L)	0016 (M) (L)	1069 (M)
	0065: Data processing system (Mel Droege). Consoles (foreground), digital racks (background). 0016: Anechoic chamber, antenna feedhorn assembly (Mel Droege). 1069: Klystron room. Each of the two klystrons is mounted in a tank containing 3,500 gallons of high dielectric strength transformer oil.
	1037 (M) (L)	1066 (M) (L)	0106 (M) (L)
	1037: Ves Fulp winds up one of the klystron hats (Ves Fulp). "That was done as a joke. Our ancillary guy comes in one morning and brought that thing, it's a toy, and said we've gotta get a picture of that. I think that was a polaroid picture. That is the klystron hat on the left, that thing weighs about 6,000 pounds. It's 3/4 inch lead with a 1/4 inch stainles steel liner. I'm standing on one platform and you can see one on the other side." 1066: High voltage room, capacitor banks (Ves Fulp). 0106: Food service (Mel Droege).
	0064 (M) (L)	0038 (M) (L)	0000 (M)
	0064: BMDOC (Ballistic Missile Defense Operations Center) (Mel Droege). Provided the major tactical control of the local Safeguard system (SRMSC). Equipment installation in progress. 0038: Cable run discussion (Mel Droege). 0000: Misc. Transmitter Recollections: Langdon Machine Shop (Ves Fulp).

PAR Complex Samples

	2003 (M) (L)	3002 (M) (L)	7394 (M) (L)
	2003: PAR sunrise (Curtis Schweitzer). 3002: Aerial view just after construction completed (Denis Abbott). The Nike Hercules target tracking radar can be seen on the roof without its radome. It was used to help align the phased array radar. The low buildings at the left rear of the PAR were used by the installation and test teams and were removed after activation. 7394: View from the west, power plant in the foreground (HAER).
	3006 (M) (L)	1080 (M)	3026 (M) (L)
	3006: Aerial view looking north (Denis Abbott). 1080: Antenna element installation (Ves Fulp). Underside of installation cabs and their supporting framework can be seen in upper right part of photo. These cabs travelled up and down the antenna face to allow work to continue in all types of weather. 3026: Power splitter under test in TWT (Travelling Wave Tube) test area (Denis Abbott). Vertical cylinder is a TWT that supplies the RF power for the PAR radar system. The TWT is approximately 8 feet long. This equipment is normally used to test TWT's prior to installation but in this photo it is configured to test the power splitter in the foreground. RF power leaves the tube at the top and is routed to the right and downward to the splitter under test.

RSL Samples

	0128 (M) (L)	7474 (M) (L)	7487 (M) (L)
	0128: Sprint missile silo liner (sleeve) being installed in the launch cell at RSL 2 (Mel Droege). 7474: RSL 2 main gate and LASS (limited area sentry station) (HAER). 7487: RSL 3 power generation room #124, showing no-break units NB-1002 (A) and NB-1001 (B) (HAER). This equipment consisted of a 150 horsepower, D.C. operational motor which drove, on each end of the extended shaft, a 70 kw generator and a 30 kw generator unit. It was designed to provide continuous power service for launch equipment.

Miscellaneous Samples

	7001 (M) (L)	4001 (M)	0161 (M) (L)
	7001: Operational diagrams (HAER). 4001: Pages 10 and 11 from W/SC (Western/Subcontractors) Telephone Directory, Safeguard Site I, North Dakota Complex, September 1974 (Roger Thompson). 0161: 8-plex personnel housing units, Cavalier, ND (Mel Droege).
