Nike Zeus Operational - from Michael Binder - June 2016
Nike-Zeus ASAT was operational on Kwajalein beginning 1962 or 1963 (I believe) under Project/Operation MUDFLAP (Program 505?) before being replaced by the Johnston Island-based Program 437 Thor ASAT ca. 1964.
"OPERATION NIKE-ZEUS in the Marshall Islands (Kwajalein)" from Roma Scougal - 2013
Roma Scougal was looking for a repository for two Zeus books from her father, H.D. "Scoug" Scougal who had worked on Zeus. She was worried that they would be "lost" in the volumes in a museum. (and I presume hoped they would be more accessable with me)
Weeks later, USPS delivered a large thin box from "Big Lake", Alaska - look it up - it is right next to "Never-Never Lake", Alaska - yup really -
The books were glossy, promotional type books of the Nike-Zeus operations in the Marshall Islands (Kwajalein).
If they were intended to be "coffee table books", I have seen smaller coffee tables !! The books are 20" x 16" !!
The books "OPERATION NIKE-ZEUS" are identical
but one has the transparent overlay cover

The printing inside is normal size - so you get a lot per page !!
To digitize a page required 6 scans/page and the stitching of the results together -
I recommend the (free) "stitch" program from Microsoft "Microsoft Image Composite Editor"
You have the cover above. These large format images are best viewed on a big moniter !!
Each file is < 4 MBytes. pages 01-08, pages 09-16, pages 17-24, pages 25-32.
(Firefox is SLOW with big format .pdf images, best use Internet Explorer.)
also included was a somewhat aged 5"x3.5" photo "Photo taken by "H.D. "Scoug" Scougal"
Zeus -from Adrian Popa - 1999

In the late 1950s while in the antenna lab at Douglas Aircraft Company (DAC), Santa Monica.
I worked with Western Electric (WE) people on the development of the microwave systems for NIKE Zeus. We also worked on the much ballyhood Hecules intercepting Hercules experimental tests.
On the Ajax and Hercules programs DAC was the prime contractor and WE was a subcontractor. On the Zeus (later Spartan and Sprint) programs the roles reversed with WE becomming the prime contractor and DAC the sub. This was the beginning of the electronics costing more than the missiles and aircraft that contained them, something that the airframe manufacturers have had problems with to this day.
DAC fabricated the NIKE missiles and WE supplied the guidance units and microwave assemblies. We lost the command guidance on several of the first Zeus launches and we did all kinds of environmental and vibration testing to try and find the trouble. The Zeus traveled so fast that the antennas burned up in the outter atmosphere.
Special ceramic materials had to be developed to cover the antennas to protect them. We called them eyeballs because they were made of white pyroceramic about the size of baseballs and looked like eyes on the missile. Other misiles such as Thor also were having this loss of telemetry problem and we ended up testing the missile microwave sub systems in a vacuum, something that had not been done before.
What we found was that in the thin atmosphere (about on micrometer mercury pressure) the transmitters in the missiles were forming a plasma glow in the thin air around the antennas cutting off the microwave signals. There is no way to fix the problem except to turn off the transmitters.
Later in the manned space programs this region of the atmosphere became better known as the loss of signal (LOS) region during rentry .

Radar Energy Density -from Adrian Popa - 1999

I've been reading more deeply into your NIKE web site and I have more comments.
There is a classic paper "Some Technical Aspects of Microwave Radiation Hazards" by W.W. Mumford in the Feb. 1961 Proceedings of the Institute of Radio Engineers(IRE). Mumford was at Bell Labs at the time and he discusses 45 of the then current high power microwave radar and communications system systems including NIKE. In rank order the worst hazard is the FPS-16 precision track, the HIPAR is 4th on the list , Herc. Imp TTR is 6th, Ajax MTR is 11th and Ajax Acq is 12 th. When I read this article in 1961 it scared the hell out of me for we were expecting our first child and I recalled that we all worked every day with in the hazard zones of the NIKE radars.
The maximum power density in milliwatts per square cm (mw/cm^2) is not at the aperture but at a distance of about 0.1 times the aperture diameter squared divided by the wavelength. At this distance in the antenn near field the power density is or more 5 dB greater than the aperture power density. To reach the arguably safe power density of 10 mw/cm^2 you must keep the following distances away from the aperture when in the center of the beam:
A few of the systems listed include:
If you would like a copy of this 21 page paper I'll be happy to send one to you. Perhaps the IEEE would let you post a copy on your web site.
System Distance in feet for 10mw/cm^2 power density FPS-16 1020 FPS-6 560 NIKE HIPAR 550 NIKE Imp. TTR 400 Ajax MTR 270 Ajax Acq 260 TPS-1G 150 Ajax TTR 132
In those first days of NIKE operation in 1954-55 most of us were not trained in NIKE or radar school, they would come in late 55 & 56. We had some old AAA artillery officers running the battery and a bunch of airplane mechanics learning on the job and from the manuals. I'm still amazed that we got the system to work so well. We often tracked anti-submarine aircraft at negative elevation angles down the Puget Sound and we were often in the beam center less than 100 ft from the apertures! We drew sparks off our tools and some guys could hear the pulse rep rate in there heads. I estimate that we were in fields of about 50mw/cm^2. If you had a wrench (dipole antenna) in your hand or pocket you might get burned from the arcing. Our field telephone lines were draped in the air to the control vans and we would get shocked by the detected microwave energy when using the telephones. Needless to say we stopped using the field telephones when the radars were operating. This problem was also described in the October 1961 Proceedings of the IRE in Oct 1961 by a GE radar engineer.
When I was in engineering school at UCLA in the 1960s they had an air force contract to couple UHF audio modulation into directly (wireless) into the heads of helicopter crewmen for communications purposes . This non thermal phenomenon worked well but they found out that the power density required to have reliable communications was still much greater than 10mw/cm^2 safe limit and the project was stopped before someone's brain was cooked.
The new high power satellite cell phones are opening up this controversy once again.
This weekend I'm going to try to write a note about the great air raid alarm of 1955 when the west coast air defense system all thought WWIII was starting. This has not had much press and I'll have to track down the old newspaper articles on it to refresh the details. Do you recall this day!
