Feels like the title needs some sort of "2002" notice - the reporting is recent but the actual wargame was done in 2002 and only recently declassified. So, of course, the US military's vulnerability has only increased in spades since 2002 due to drones. All those bases in the Middle East that were supposed to help protect the countries where they were based were just ripe targets. I think more critically, most of the…
I'm not sure a carrier strike group would actually outright lose to a giant swarm of drones, at least in terms of the carrier being sunk. A Shahed warhead is pretty small once you're using it against large warships. That said, I wonder why you don't see Ukraine and Russia doing this more -- "saving up" for massive clouds of long range strike drones every couple weeks, instead of sending out a couple hundred every nig…
There are real technical limitations to operating large numbers of drones simultaneously. They are competing with eachother for bandwidth, and the more you squeeze in the weaker they all become to jamming. You need to coordinate larger teams with more resources to operate lots of drones all at once, rather than resupplying smaller teams periodically. Once you have enough drones flying toward a target to survive the defenses, any additional drones are wasted; and for the moment most air defenses are either too expensive or too limited in the number of targets they can simultaneously handle to require large swarms. Smaller numbers of more capable drones can outperform larger numbers of cheaper drones - 1 drone with an 80% chance of neutralizing the target might be cheaper than 2 drones which individually have a 50% chance for a total of 75%; and 2 such drones beat 5 cheap ones. Finally, big attacks are more likely to be detected, either prior to the attack by espionage or while in transit by radar and other sensors - minimizing the time that defenses have to respond or for targets to flee can be much more advantageous than having an extra munition.
All around you want the minimum necessary to get the job done.
