Video On Starfish Prime

As you can see, the explosion was roughly spherical; the shock wave expanding in all directions roughly equally since there is essentially no atmosphere at that height.

Operation Teak. One of the first upper atmosphere tests. It used the Von Braun Redstone rocket on Johnston Island.The 3.8 megaton detonation was planned to occur at an altitude of 250,000 feet approximately six miles south of Johnston Island. However, due to a programming failure it burst directly over the island at the desired elevation making the island the effective ground-zero. This brought the explosion 2,000 feet (approximately 2/5ths of a mile) nearer than intended to the launch site control and analysis crews

My point is that Electomagnetic Pulse is a phenomenon that is common to all nuclear weapons to one degree or another.  Multi-stage thermonuclear weapons tend to have less EMP, or at least their EMP is overcome by other weapons effects. 

In any case, if you detonate a nuclear device at about 400 miles in altitude directly over the center of the Continental United States, it would induce a massive Compton effect in the atmosphere that would effectively destroy nearly every civilian electrical device on the Continent, including a significant portion of Canada and Mexico as the footprint would be circular. 

Essentially, the weapon generates a massive amount of X-rays and Gamma rays, and the ones that emit downward and strike the atmosphere, induce highly charged particles that go straight down and induce a massive electrical spike in any device they encounter.  The pulse is strong enough to melt high tension leads in half.  Anything that has an electrical coil inside, like every single electrical transformer and motor, would have such a massive electrical spike induced that the coil itself would likely disintegrate instantly and result in an impressive explosion and fire. 

I saw an estimate once, that if every electrical transformer in the United States were destroyed it would take the entire output of the remaining industry World wide, a decade or more to replace all of those transformers.  There are some power relays and other massive electrical components in our grid that are so critical that the loss of just one would be a catastrophe by itself. 

All of these facts have been known for a long time, largely as a result of the research that was conducted during Starfish Prime.  Like 'em or not, we learned one hell of a lot during these tests, and Army guys were not just sitting around watching all of the pretty lights......

The Americans and the Russians have flown warheads through high altitude bursts to see whether they would be able to complete their missions. During the Cuban Missile Crisis, the Russians conducted two high altitude tests.The United States was planning the Uracca test in the Fishbowl series which was supposed to be the big one. The explosion was to take place 500 miles up in the atmosphere  Very high altitude Thor-delivered 1 MT bomb test cancelled for fear of destroying satellites. There were also concerns that astronauts would be exposed to high amounts of radiation.In fact, President Kennedy devoted an entire meeting to the Uracca test.
