I'm not really sure what to think of this. I thought it would be more about how physics and the military intersect, but like other reviews say, it's kind of all over the place. It was a rough read. The first chapter nearly made me put the book down. Then, in the second chapter, though, it gave a history of physics and navigation. I don't know if this was so much about the "alliance" between astrophysics and the military, but more about well ... I don't really know.
