The Russian crafts had positioned themselves unusually close to the American, in a near-identical orbit, and they had synced their paths with USA-245—a classified, multibillion-dollar KH-11 satellite, equipped with imaging systems on par with the Hubble telescope—such that one of them came within twenty kilometers of it several times in a single day. Satellites in the same plane may on occasion pass within one hundred kilometers of one another but far less frequently. The Russians, it seemed, were stalking an American spy satellite.
Good read on space-warfare abilities. Those folks with wikipedia on a drive and LoRa communicators ain't seeming quite so eccentric at the moment.
