Ukraine is still recording issues with the Starlink network, sources within the defence ministry say, after Donald Trump said limits on the satellite uplink had been reversed by Elon Musk. The sources told the BBC that instances of drones experiencing connection loss at speeds of 161km/h (100mph) were being recorded, hampering military operations.

Musk previously said he was not behind the slowdown, which affected Ukraine's ability to use attack drones and co-ordinate defensive operations. The Ukrainian defence ministry sources said the military was constantly monitoring the performance of both the Starlink and Starshield networks.

Last week, Kyiv said uplink speeds to the low Earth orbit satellites had been restricted, affecting the speed at which drones could travel. Any drone travelling faster than 100mph lost its connection, officials said.

Shortly after, Musk said that Starshield, which Ukraine uses for some of its operation, was controlled by the US military and suggested that the Pentagon could be behind the issues. The White House has since repeatedly denied deliberately placing limits on the network in Ukraine.

Trump refused to say whether he had called Musk to ask him to lift restrictions to the service when asked about reports to that end on Thursday, but said: " Bottom line, he put it back." Ukraine uses both the civilian service Starlink and the more secure Starshield, depending on what communications are needed.

The networks use 10,000 satellites to provide connectivity, particularly in remote areas and on the battlefield. Starshield allows Ukrainian drone operators to see targets in real time, as well as operate interceptor drones.

Russia is not authorised to use Starlink, so when Ukraine sends long-range missiles deep into Russia to hit oil refineries, the network does not work. One Ukrainian soldier said there was "simply no alternative" to Starshield, adding that earlier in the week, connectivity had been cutting out when his unit had been travelling in a car at 80km/h (50 mph)."

I'll tell you this much: God forbid they shut it off completely - it would be an absolute catastrophe," he told the BBC. " We need a backup option for securing communications and internet."

Another soldier said they had reverted to the "proven algorithms" they used before they had Starlink when it initially started playing up, but stressed that Ukrainian forces did need the network, citing its speed." Even one or two seconds is critical when we can transfer data and orders faster," she said.
