Russia installed a radio-jammer that interferes with the signals that direct GPS-guided munitions. Last week, Ukraine blew it up ... with a GPS-guided bomb.
No, but there are actually very low very cost, extremely dangerous and illegal, jammers you can make with not too much more. Basically they just burst shitloads of electrical power into the air that jamm up a surprisingly broad range of nearby RF spectrum.
By the time £3.999m has been siphoned off on bribes and corruptionnecessary overheads, you should be happy with the coathanger and a car battery, comrade.
Was making a joke with you, about how much the Russian army loses in corruption and how their prices are not to be believed. Wasn't having a go at you. Try to be a bit more chill?
