Through past nuclear testing, the Department of Defense and the Atomic Energy Commission determined that a nuclear weapon exploded at high altitude with a sufficient yield would cause adverse effects on communication and radar devices.
This technically oriented video, which uses many animated audio-visual aids to explain scientific points of interest and explores the weapons’ effects on military systems. The first portion deals with
a hypothetical reentry vehicle armed with a nuclear warhead. The video explains how three different nuclear detonations might be required to track and destroy the incoming vehicle. The next portion explains how a nuclear explosion would more adversely affect the low-power downlink of radio transmissions to aircraft or satellites than the more powerful uplink. Other atmospheric chemistry and infrared systems problems are discussed in the video.

I like how the narration on these films is always so matter of fact. Like they’re describing how to replace an engine transmission. No biggie.

Perking it up would spoil the Effect.

Awesome video but date is definitely later than ‘63. I would estimate at least ‘69-‘70 based on the images of the AN/FPS-85 phased array radar early in the program. That was the first operational phased array radar in the world (unless one considers MAR-I at White Sands tested as part of the Nike-X program “operational”) but was not completed until late 1968. Plus most of the knowledge gained on high altitude nuclear effects was gained in Operation Dominic of 1962, the US’ final series of atmospheric nuclear tests. Seems a little doubtful the phenomenon would have been so well understood less than a year later. Also the computers shown look a little advanced for the early 60s.
Really really awesome find though and a great companion to the 20 year history of the ABM effort to be found on the AT&T channel.
Thanks! It's what the DOE listing said, but I removed it from the title line.
The computer simulations and satellite technology would agree with this.
"date is definitely later than ‘63"
Fine observation.
Public archive listings are often huddled over by overworked individuals, completing a list.
One would have to take a look at markings on the actual film box or the content itself to conclude a plausible contextualization of the source material.
The context, explictly mentioned here would be: _recent_ *computing of combined RADAR and infrared sensor data* as well as the preceeding infrared computing model of *OPTIR* ( *'Optical Infrared Code'* 4:19 ) .
A second version of said computing model is mentioned in *1971* : apps.dtic.mil sti citations AD0734046
A research report by THE *AIR FORCE GEOPHYSICS LABORATORY* from *1978* still describes OPTIR - without naming a specific date of introduction it seems:
apps dtic mil sti pdfs ADA104513 pdf
A program called AIRCAP was published in 1974 by Gerald M. Daniels in 'Optical Engineering', but it's a bookworm's assumption that the physics may somehow relate - the name itself doesn't seem to appear in the above archive or report.
*EXCEDE SPECTRAL* from October 19th of 1979 appears to be the relevant series of experiments, narrowing the date of the information flic between 1971 (still hoping for a better model) and 1979 (experimental data) - it takes a specializing military historian to nail it down further (e.g. calling, or personally looking at the film box at the Department of Energy...).
The sideburns at 11:30 is another late 60s early 70s dead giveaway
Oh how I enjoy these old explanatory films - especially ones dealing with nuclear weapons and their effects. In a way, it's the same sort of fascination that a young boy has when he sets off a firecracker, except on an incredibly large scale. Despite their potential use as a mechanism by which to bring death and destruction of unimaginable scale, weapons of such magnitude and consequence are inescapably interesting to curious minds. Thanks for the uploads.
Thanks for uploading these! Interesting.
Very interesting to see the FPS-85, this an is an area that I am currently doing research in, on how the D, E and F layers can impact radio signals no just at HF.
All that work AT&T did and for next to nothing. This itemises one of the complicating factors in ABM defence.
I've never connected those Johnson Island tests with the ABM programme before. It's so obvious now ...
"Multi Megaton" .......thank God we made agreements and that most deployed warheads are variable yield 650-850 kt or 900kt.
I don't think this is something easily treated with Organic Locally Sourced Honey.
But this Information is Astounding!
Great video! Reminds me a lot.

240p..? The picture is as 'fuzzy' as a brand new teddy bear.
It's generally comforting when nuclear weapons are _effecting systems,_ as it's a fairly reliable indicator that we're not dead at that precise moment yet.
Oh the stupidity of military system over reliance on the GPS sat nav net.
Last Time I Was This Early, Quantum Mechanics was still being done in Gasoline Alley.
I think they very quickly realized that the incoming velocity of MIRV's would be so great that virtually nothing could be quick enough to provide any real _Defence_
This is why the USA scrapped their perfectly functional 'Nike' defences and such, and currently has no official means of defence against *any* incoming object above a certain velocity
So Hyper Velocity Weapons are Obsoleted?
@jayc2469 You fundamentally misunderstand ***interception***. You also seem completely unaware of the known characteristics of the Sprint missiles.
More modern systems such as Aegis and hardware such as the SM-3
One begins to suspect you do not grasp the realities of much of these systems, strategies or even basic concepts.
