Elon turning off Russian access to Starlink by whitelisting only authorized terminals in the region was a turning point for Ukraine's success. The conflict has proven that modern warfare depends on Starlink and its mimics.
'A new piece of electronic warfare equipment appears more precisely targeted, apparently capable of jamming Starlink terminals on the ground across an area of up to 20 square kilometers.'
The specifics of an implementation of this are objectively absurd. Power requirements alone make this a non-starter. If that weren’t enough, it would be a declaration of war.
Not to mention they are spending an awful lot of money on developing anti-satellite missiles for having a working directed-energy weapon that can do the same.
I'm sure they are experimenting with directed-energy ASAT technology though, because why wouldn't they?
