SpaceX throttles Starshield, halting Ukrainian interceptors

SpaceX restricted the speed of terminals connected to Starshield, the military version of its Starlink satellite internet service, last week. The change prevented equipment moving above certain speeds from maintaining a connection. Ukrainian armed forces rely on this network to guide interceptors that counter Russian bomb-carrying drones.

The slowdown caused these interceptors to fail at high speeds. Russian forces exploited the gap to strike energy infrastructure across Ukraine. Ukrainian authorities reported that two people died and at least 17 were injured in the resulting attacks.

The Ukrainian military stated it received no advance notice of the restriction. President Volodymyr Zelenskyy characterized the move as a direct message from the United States. He made these remarks as tensions rise between his government and President Donald Trump's administration.

Public reaction focused on the lack of coordination. Critics targeted President Trump for perceived abandonment of Ukraine and SpaceX Chief Executive Officer Elon Musk for enabling the administration. The sudden cutoff generated widespread criticism across political lines.

Explanations for the decision have changed over the past week. Musk initially claimed SpaceX did not control Starshield and that the US military made the decision. The White House denied taking action. Later reports indicated that Musk proposed the slowdown to Trump, who accepted it. Subsequent accounts stated that Musk ordered the restrictions directly. Access to the service in Ukraine has since been restored.

Ukraine depends on US technology for defense, including Starlink and Starshield. Access has been limited in the past. In 2022, coverage was not extended to support a counterattack in Crimea. Experts say the current episode demonstrates how much geopolitical leverage has accumulated in the hands of a single unelected executive.

This concentration of power stems from the structure of the space industry. Wendy Whitman Cobb, a professor at the School of Advanced Air and Space Studies at Maxwell Air Force Base, said SpaceX effectively holds a monopoly on launch. She noted that rivals such as United Launch Alliance, Blue Origin, and Rocket Lab exist but do not match SpaceX in frequency, mass, scale, or cost.

Space economist Oğuz Karasu of the Oxford Space Initiative described the monopoly as practical rather than legal. He stated that launch accounts for about 8 percent of the space industry, but the rest of the sector cannot function without it. SpaceX has built a network of more than 10,000 Starlink satellites in low Earth orbit using Falcon 9 rockets.

Andrew Reddie of the University of California, Berkeley, called the situation almost an antitrust issue. He noted that SpaceX launches support constellations it owns, leaving little incentive to launch competing systems. SpaceX has launched some Amazon Kuiper satellites, now called Leo. Whitman Cobb and Karasu said they have heard complaints that Falcon 9 prices for low Earth orbit are rising, and Starlink prices have climbed since its 2020 beta.

NASA and the Space Face face exposure from this dependency. SpaceX is reportedly retiring the Falcon 9 and taking no new missions from 2028. The Space Force is struggling to find launch options for military satellites. Questions have also arisen regarding NASA's future access to the Crew Dragon capsule. A Falcon 9 issue in February briefly grounded the rocket and raised concerns about the Crew-12 launch. NASA continues to back Boeing's Starliner and contract with Rocket Lab and Blue Origin.

Michele Scataglini of the Oxford Space Initiative said the market needs more competition, otherwise it is not a market. Reddie said the central security problem is that a non-state actor is making decisions as if it were a government. He noted that this episode directly affected Ukraine's defensive capability. Scataglini called it a global wake-up call and warned that one firm could decide which countries get access to space, particularly in the Global South. Whitman Cobb said she is cautiously optimistic that the events will raise awareness of the risks of reliance on a single company, though it took people dying for the problem to be recognized.
