Great comment, I have little to disagree with; in a non public forum I'd probably get salty about having yet more expansion of US feet on the ground in Western Australia. This, though: The Chinese say they have worked out how to use LEO satellites and something like geomagnetic anomoly detection to find big subs at sea, the myth of "it's hidden in the ocean" may be exposed inside the next 10 years. is worth a comment - I strongly doubt LEO's can use "something like geomagnetic anomoly detection to find big subs at sea". The distances are to great and the signal domain is too noisy. I spent a decade or so doing the technical backend for geophysical exploration aquisition and processing, and any blip a sub makes in the daily flux of magnetic signal at the surface will be static noise at LEO altitudes. There's merit in the notion they can be detected via disturbance in magnetic backgrounds, I suspect mention of LEO's might be a misdirect.
