Ukrainian officials reported that disruptions to Starshield, a satellite communications system linked to Elon Musk’s SpaceX and paid for in part by European countries, have significantly impacted their drone operations and air defenses. Starshield, a more advanced counterpart to the widely used Starlink internet network, is vital for drone flights and certain military communications. However, recent restrictions have caused drones to lose connectivity at speeds as low as 40 miles per hour, with some regaining connection only when flying below 100 miles per hour. This limitation undermines the effectiveness of some Ukrainian drones and interceptors, which typically exceed these speeds during operations.
While Starlink provides basic communication capabilities, Starshield is critical for more complex maneuvers on the battlefield. Ukrainian forces have been forced to adapt to the new speed limits for drones, but officials say the restrictions have undermined their ability to thwart Russian drone attacks targeting Ukrainian cities.
President Volodymyr Zelensky described the satellite slowdowns as a “planned operation” and has called on the United States to restore full functionality. Zelensky has expressed concerns that the connectivity might never be fully reinstated or could be abruptly cut off again, forcing Ukrainian troops to divert attention from combat to develop workarounds.
The cause of the throttling remains unclear. SpaceX founder Elon Musk has stated that Starshield is controlled by the Pentagon, while U.S. officials have given mixed messages. Secretary of State Marco Rubio suggested that SpaceX decides access to the system, fueling confusion over responsibility. A White House official maintained that no authorized changes to Ukraine’s satellite internet had occurred, and former President Donald Trump denied involvement in any restrictions.
Some U.S. lawmakers have weighed in, urging the restoration of Ukraine’s satellite communications amid concerns that disruptions jeopardize critical U.S. intelligence sharing and Ukraine's air defenses. Senator Thom Tillis, after a video call with Zelensky, warned that weakening Ukraine’s satellite connectivity and air defenses could embolden Russian President Vladimir Putin and prolong the conflict.
In response to calls about the cause of the disruptions, Rubio said no deliberate denials of aid had occurred and cited global shortages of Patriot missile interceptors, which Ukraine has also requested. Treasury Secretary Scott Bessent criticized Zelensky’s suggestion of deliberate U.S. action as “very reckless,” reflecting political divisions in Washington.
On the ground, Ukrainian commanders report that the speed restrictions have tangibly affected operations. Brig. Gen. Andriy Biletsky noted that drones previously maintained stable connections at speeds up to 250 miles per hour but are now capped at 100 miles per hour, limiting their tactical use. He emphasized that slowing interceptors hampering attacks on jet-powered Russian drones is particularly damaging for Ukraine’s civilian defense.
Some Ukrainian soldiers have voiced frustration, feeling abandoned by restrictions they see as politically motivated rather than technical. Lt. Yuriy Butusov of the 23rd Assault Regiment described the slowed connections as effectively granting a “vacation day” to Russian forces, resulting in greater Ukrainian casualties and material losses.
The satellite communication disruptions have deepened concerns within Ukraine’s military about reliance on external support that could be altered by foreign political considerations, complicating efforts to defend the country against ongoing Russian aggression.
