Having read thru the thread again, I think it's fair to say that there are a few points for discussion that may have been missed / need elaboration.
#1. EMP & the public - As I stated earlier, I feel that the general public isn't aware of how EMP would affect there lives.
If there was an mid-air / high altitude accident & a B1 / B2, or a B-52 carrying a live warhead caused the weapon to detonate over the US, depending on many variable factors (including yield (in Kilo or Mega tons), height of the A/C at the time, positioning over the country, etc.), then a large percentage of the country could effectively be driven back to the stone age in an instant. While that thought could spread a panic, the Likelyhood of such an event is so slim that it really is a "What If..." scenario, so his "hidden" to some extent.
#2. EMP & the Military - Again, as stated previously, the Military are AWARE of EMP, it's effects & how to combat these effects. It's also fair to say that like the accident mentioned above, the likelyhood of WW III taking place is slim, even with the M.A.D.(Mutually Assured Destruction) policy. And in following with the accident scenario, if WW III took place then most of the globe would be driven back to the stone age, meaning an even playing filed (
albiet a radioactive one !), thus negating a need for equipment that can withstand EMP.
#3. EMP & the cost of preparing for it - Also stated previously, to engineer/design a ship/missile/vehicle such that it's considered EMP Proof, then test it to prove that it is, is highly expensive & would no doubt double or quadruple the actual cost of each production unit, to help offset the testing costs.
This testing / over engineering, while meaning that the equipment would operate after an EMP blast, would more than likely make it less financially attractive to the bean counters in power, thus meaning less sales & less profits for the manufacturer. In addition, such testing would add additional time onto the length of time before the equipment could be classified operational, and possibly lead to the technology being "out-of-date" by the time it actually comes into operational service.
And all of this is really just as a back up, so that we have equipment that would operate after a Nuclear holocust.
Don't get me wrong, there are Facilities in the US that DO conduct EMP testing (
possibly at either China or Groom Lake ).
The test facility I'm refering to was demonstrated on an episode of the discovery channel programme "Future Weapons". They took a reasonably modern car & subjected it to an EMP Blast from a "Pinch" device. While the lights still worked afterwards, the car couldn't do anything else as all control circuits for the electric gadgets, such as windows, door locks, etc. as well as the Engine Management CPU, where all fried in the blast.
That aside, I don't think that the facility can duplicate EXACTLY the power that would be produced in a nuclear blast. Also, it's ground based & in the desert 100's of Miles from the Ocean, so not a lot of use for ships or aircraft.
