400km/h: The Speed Limit That Restored Ukraine's Satellite Link

Ukrainian military commanders regained full access to their primary satellite communication network on Saturday, marking the end of a brief but critical disruption.

Defence Minister Yevhenii Khmara confirmed in a public statement that the connection is now stable. He noted that speeds exceeding 400km/h are once again possible, a metric that signals the restoration of full capability on the network.

The restoration of high-speed connectivity is vital for the front lines, Khmara explained. Reliable data links are essential for the operation of autonomous drones, the coordination of logistics, and the maintenance of secure communications for soldiers in the field.

Kyiv relies heavily on Starlink and its more secure, military-grade counterpart, Starshield, to pilot drones and manage operations across the country. The network, which consists of 10,000 low Earth orbit satellites, is particularly important in remote areas of the battlefield where traditional infrastructure is lacking.

The recent restrictions emerged during a period of diplomatic tension between US President Donald Trump and Ukrainian President Volodymyr Zelensky. Ukrainian officials previously accused Trump of instructing Elon Musk, the owner of Starlink, to impose limits on the service. Under those limits, drones reportedly lost their connection when traveling at speeds of 161km/h or faster.

Trump denied giving such an instruction but later acknowledged that Musk had restored the service. Musk has suggested that the Pentagon, which controls the Starshield system, may have been behind the recent technical issues. This technical dispute occurred alongside a broader disagreement over Ukrainian strikes on Russian oil infrastructure.

The diplomatic row intensified as Trump prepared for the midterm elections scheduled for next month. He waived certain sanctions on Russia and agreed to a deal to import Russian diesel for the US market, a move that drew criticism from Ukraine and its European allies. Trump argued that Ukrainian strikes on refineries were pushing global fuel prices higher, while Kyiv maintained that those attacks were necessary to cut off a primary revenue source for Moscow's war effort.

Zelensky stated that the US threatened to withdraw intelligence sharing if the strikes continued, a claim Trump also denied. The dispute over connectivity highlights the strategic importance of satellite technology in modern warfare, particularly as Russia is not authorized to use Starlink, leaving the network inactive when Ukrainian assets operate deep within Russian territory.

Fighting on the ground continued alongside the diplomatic developments. Russia's defence ministry reported on Saturday that its air defences shot down 616 Ukrainian fixed-wing drones. These drones struck several regions, including the Russian-annexed Crimean peninsula, where local authorities introduced restrictions on electricity and water following power cuts caused by the strikes.

Ukrainian authorities stated that in the past 24 hours, they targeted a missile component manufacturer, a chemical plant, and an aircraft at a military airfield inside Russia. They also reported that Russian forces carried out 88 air strikes on Friday, deploying 309 glide bombs and 10,270 kamikaze drones in the offensive.
