I know both US and Russia are very advanced in jamming. When your navy or whatever it is needs help, how will they communicate effectively? Don’t they always need their own strength to resist attacks? Please, the best military strategy has to be cost effective. If you can do the same job with 50 billion dollars a year instead of 1 trillion, why not? Jamming affects only low-frequency waves. High-frequency waves remain unaffected. Since you know who is where perfectly within your community, why not just beam your communication with high-frequency waves? Military communication will have to go through stealth satellites that change their orbits from time to time, because they can be downed easily. However, commercial ships can and should still communicate through commercial satellites, just because pirates and military forces of their grade don’t have anti-satellite technology yet. You don’t want to reveal the locations of your stealth satellites to all your commercial ships. Problem solved!
In any case, proper military strategic thinking works more like a computational model that can be tested against loop holes. It’s supposed to take a think tank about a couple of years to do it right. It makes sense, because you invest a couple of years for the next couple of decades, well worth it.
