IMO a viable deployable EM rail mount mini-nuke platform is the way to go. In a single portable configuration that has enough capacity to generate the EM launch of a relatively long range mini-nuke would be the ‘go to’ configuration.
All it really would take is just one launch.
The British were in fact betrayed.
The Skybolt system was being developed at Eglin AFB. My Father worked at building 100 which was the headquarters for the program.
There were British officers all over the place. The Brits had cancelled their own program to work jointly with the U.S.
Just out of the blue, the U.S. cancelled the program, leaving the Brits with nothing. I can understand it if they felt betrayed because they were.
My father worked at the Douglas Aircraft Santa Monica during WWII. Some point after that, and I’m not sure when, he transferred over to Long Beach plant where he worked until his retirement in 1979.
More foolishness from that damnfool McNamara.
