One Man's Finger on Ukraine's Air Defense Switch

Last week, interceptor drones that Ukraine's military uses to shoot down incoming Russian bombs stopped working properly at high speeds. The cause wasn't a mechanical failure or enemy jamming. It was SpaceX, which quietly throttled Starshield — the military-grade version of Starlink that Ukraine relies on — to block terminals traveling above certain speeds from connecting to the network. The interceptors, which depend on that connection, became far less effective at exactly the moment Russia stepped up attacks on Ukraine's energy grid. According to reporting, the fallout included two reported deaths and at least 17 injuries.

The Ukrainian military says it got no advance notice. President Volodymyr Zelenskyy has characterized it as a direct message from the United States, arriving amid escalating friction between himself and President Donald Trump. What followed was a tangle of contradictory accounts: Musk initially said SpaceX doesn't control Starshield and that the US military makes those calls, while the White House denied ordering any restriction. Then came reports that Musk himself had proposed the slowdown to Trump, who signed off on it — followed by yet another report claiming Musk ordered the restriction unilaterally.

For Ukrainians trying to survive a war, the question of who exactly pulled the lever matters less than the fact that it could be pulled at all. This isn't unprecedented, either — Starlink coverage was reportedly withheld in 2022 during a planned counteroffensive near Crimea. But this incident is different, according to defense expert Andrew Reddie of UC Berkeley, because it appears to have hit Ukraine's defensive capability rather than an offensive operation. "And then you end up with all the harrowing images of apartment blocks on fire and people getting pulled out of the buildings," he said.

The incident has reignited a bigger question that extends well past this one war: what does it mean that a single company, run by a single person, has become this essential to global security — and nobody elected him to that role?

A monopoly in all but name

SpaceX went public recently in an IPO that positions it as one of the most valuable companies on Earth, built initially on its rocket-launch business before Starlink became its dominant revenue source. Its Falcon 9 rocket is the most-launched in history, and its rideshare program — letting smaller satellite operators buy space on a single launch — has pushed launch costs to historic lows, opening orbit to startups and university labs that could never have afforded it before.

That success has a flip side: SpaceX now effectively controls access to space.

"For all intents and purposes, SpaceX has a monopoly on launch right now," said Wendy Whitman Cobb of the School of Advanced Air and Space Studies. Competitors exist — United Launch Alliance, Blue Origin, Rocket Lab — but, as she put it, "nobody comes even close to SpaceX in terms of frequency, mass, scale, cost. I mean, they've got everything in the bag."

Space economist Oğuz Karasu of the Oxford Space Initiative makes a similar point with a number: launch makes up only about 8 percent of the entire space industry, he said, "but without that 8 percent, you can't have the rest of it." Control the launch pad and you control everything that depends on it.

That leverage compounds because SpaceX isn't just a launch provider — it's also the owner of the single biggest customer for its own rockets. The company has used its cheap, frequent Falcon 9 flights to build out a Starlink constellation of more than 10,000 satellites in low Earth orbit. "There is no incentive for a SpaceX launch to be used to provide constellations for other countries that would compete," said Reddie.

SpaceX has launched a handful of satellites for Amazon's rival Kuiper (now Leo) constellation, which Reddie suggests could be read either as a hedge against antitrust scrutiny or simply a sign of how little SpaceX fears the competition. SpaceX did not respond to a request for comment on any of this.

Where monopolies lead

The textbook pattern with monopolies is that prices eventually rise once competition is squeezed out. SpaceX doesn't publish its launch prices, but Whitman Cobb and Karasu both said they've heard complaints that Falcon 9 launches, especially to low Earth orbit, are getting pricier. Starlink's consumer pricing has also climbed steadily since its 2020 beta launch.

There are legitimate reasons prices rise — inflation, rising costs — but a dominant company now also has shareholders to satisfy, and not much competitive pressure holding prices down. It's a pattern familiar from elsewhere in Silicon Valley: undercut rivals with investor-subsidized pricing until the market is cornered, then raise prices once customers have nowhere else to go.

The stakes here go beyond pricing, though, because space infrastructure quietly underpins everyday life in ways most people never think about. GPS and satellite communications sit behind gas pumps, ATMs, financial transactions, emergency dispatch. "If GPS goes down, you're not going to be able to get gas at the gas pump, you're not going to be able to get money out of the ATM," Whitman Cobb said, "let alone not be able to do financial transactions or get an ambulance to the right place on time."

No one thinks Musk is likely to black out Starlink worldwide on a whim. The concern is structural: when one company controls the infrastructure that so much of modern life quietly depends on, that company's owner ends up with an outsized amount of leverage over everyone else. "All of our current economic activities are based on space technologies right now," said Karasu. "Giving this much control, or this much power, to one person is not good for society's future."

Even NASA is stuck

The dependency problem reaches institutions that should, in theory, have options. SpaceX has reportedly decided to retire the Falcon 9 and stop taking new missions from 2028, which is leaving the Space Force scrambling for launch alternatives for military satellites and putting NASA's access to the Crew Dragon capsule — currently its ride to and from the International Space Station — in question.

This isn't a hypothetical risk. After the Space Shuttle Columbia disaster killed seven astronauts in 2003, the shuttle program was shut down, and the US had no way to launch humans into space from American soil between 2011 and 2020. A single-point-of-failure launch system has already cost the country a decade of independent access to orbit once before.

It's part of why NASA keeps funding Boeing's troubled Starliner capsule despite years of delays — and why, when a Falcon 9 issue temporarily grounded the rocket in February, there were real worries the Crew-12 mission to the ISS could slip. The Falcon 9 is, by any measure, an extraordinary piece of engineering with an outstanding track record. But even the best system can fail, and NASA has learned the hard way what happens when there's no backup.

"Even NASA is realizing, okay, we are putting all our bets on a single player," said space business expert Michele Scataglini of the Oxford Space Initiative. "The market needs to have more competition, otherwise it's not a market." The trouble is that SpaceX's lead isn't just about rockets — it's reinforced by sister companies working on batteries and AI that feed back into the whole operation. "These are all self-reinforcing capabilities for the firm," Scataglini said, "that I would say none of the other players alone possesses."

A non-state actor making state-level calls

Starlink access in Ukraine has since been restored, but the country remains dependent on a system it doesn't control. Reddie frames the deeper issue plainly: "You've effectively got a non-state actor making decisions as if they're a government."

Scataglini called the episode a global wake-up call. "There's a single entrepreneur that has more power than governments in deciding how strategic defense capabilities can be used," he said. And the risk isn't confined to Ukraine. If launch and satellite infrastructure keeps consolidating around one company, Scataglini warned, the deciding question becomes "which country has access to space, and which one does not" — a question likely to fall hardest on nations in the Global South that already have the least leverage.

Whitman Cobb sees a sliver of a silver lining in how visible the harm has been this time. "I'm cautiously optimistic that, at least in this case in particular, it is highlighting the dangers of being reliant on a single company, a single individual," she said. "It took something bad happening — people dying — for people to realize, oh, wait, maybe there's a problem here."

Whether that realization translates into real competition — more launch providers, more satellite operators, less consolidated power over orbit — remains an open question. For now, the infrastructure holding up GPS, satellite internet, and a live war's air defenses still runs largely through one company, answerable mostly to one person.
