When satellites are shot out of the sky, cell phones and GPS are non-existent, HF will still work.......................

Back years ago COMEXs were frequent. Then after 911 it got very much less. While I have been out of the loop for a few years I have not heard it has gotten any better.

And the need for these exercises is apparent by the article most likely providing inaccurate information. UTM coordinates are non standardized, what they should be using is MGRS (Military Grid Reference System). Or even Lat/long as that is used in various data links.

A further issue with using UTM is that it does not include the Polar regions, so if an Antarctic station wanted to participate they could not provide UTM coordinates.

The way the US Navy would do this: turn off all satellite comms without notice, and with ships at sea.

For all fleets at the same time.

I hate it when NETCOM does that because it activates the receivers that were implanted in my and every other soldier’s brain during basic training. It always gives me a headache and a desire to eat a John Wayne bar. (chocolate & toffee disk to those non-military types)
