The armed submarine drones were poised to attack the Russian fleet, according to a CNN report that cited an excerpt of a forthcoming biography of Musk by Walter Isaacson, the former chief executive of CNN. Instead, according to the book, which goes on sale Tuesday, the drones “lost connectivity and washed ashore harmlessly.”

Ukrainian and American officials scrambled to get service restored, according to the report, appealing to Musk directly. Musk eventually agreed.

But the recounting of the incident is a reminder of how SpaceX — and its founder — amassed enormous power and leverage as its competitors proved incapable of keeping up with a dizzying pace of innovation. That influence shows the delicate balance government must navigate when companies innovate faster than their competitors — or the government itself.

“One of the advantages is the huge amount of innovation coming out of the private sector, which the government wants to leverage to stay ahead of China and others,” said Brian Weeden, the director of program planning at the Secure World Foundation, a think tank. “The flip side is it gives a lot more power to the private sector and particularly to billionaire individuals who control those companies and technologies.”

SpaceX’s Dragon capsule is the only way NASA can send its astronauts to and from the International Space Station. It launches sensitive national security satellites for the Pentagon and the National Reconnaissance Office. It launches more rockets than any other company or country — this year it has already surpassed its record last year of 61 — and operates more satellites than any other entity on Earth, with more than 4,500 in orbit.

SpaceX started providing Starlink internet service to Ukraine after Russia’s invasion, creating a lifeline for the country when its communications systems had largely been knocked out. But according to Isaacson’s book, Musk grew concerned about Ukraine’s military using them for offensive purposes, according to the CNN report.

“How am I in this war? Musk asked,” according to Isaacson. “Starlink was not meant to be involved in wars. It was so people can watch Netflix and chill and get online for school and do peaceful things, not drone strikes.”

In February, Gwynne Shotwell, SpaceX’s president and chief operating officer, told reporters something very similar.

“We were really pleased to be able to provide Ukraine connectivity and help them in their fight for freedom,” she said. “It was never intended to be weaponized, but the Ukrainians have leveraged it in ways that were unintentional and not part of any agreement.”

Since reports surfaced of SpaceX shutting off satellite communication in Ukraine last year, the Pentagon has granted SpaceX a contract. The details of the contract are unknown — on Thursday Pentagon spokesman Jeff Jurgenson declined to say more “due to the critical nature of these systems.” But Weeden said placing Starlink under contract should allow the Pentagon more control and possibly prevent the service from being suddenly shut off again.

“That is the balance that the Defense Department has to grapple with as it focuses on this commercial technology: Is it losing control in some way?” Weeden said. But the government is not helpless and has ways to rein companies in: “You can address a lot of those concerns through contracting mechanism or other legal agreements,” he said.

When SpaceX first launched its Starlink constellation, Musk said the chances of success were not guaranteed. Other satellite companies had tried and failed in the past, given the enormous cost to launch and operate hundreds or thousands of satellites. But in large part because SpaceX is vertically integrated, meaning it not only builds the satellites but launches them itself on its reusable Falcon 9 rocket, it has so far been able to be successful.

In addition to being used in Ukraine, the constellation is used to connect remote communities, and it has been a key part of hurricane recovery efforts as well as in other natural disasters where connectivity is lost.

When SpaceX started Starlink, others were eyeing the market for satellite internet as well. At the time, Musk said, “it’s always good to have competition.” But Starlink has since outpaced its competition.

Another satellite provider, OneWeb, went bankrupt and then was resurrected and operates a far smaller network. Amazon plans to launch thousands of satellites but has yet to send up a single one. It is also facing a lawsuit from one of its shareholders, who alleges the company “acted in bad faith” when awarding launch contracts to other commercial companies, including Jeff Bezos’s Blue Origin, but not to SpaceX.

“Despite being the launch provider with the most proven track record and the lowest prices in the industry, SpaceX was seemingly not considered by Amazon,” the suit alleges. (Bezos owns The Washington Post. Interim CEO Patty Stonesifer sits on Amazon’s board.)

SpaceX is also the sole provider to NASA for crew transportation to the space station. But that’s not because NASA just awarded one contract. It awarded two specifically so that companies would have to compete against each other, driving down the cost and increasing reliability. But the other company to win a contract, Boeing, has yet to fly any astronauts and may not until next year, leaving SpaceX as the only provider.

“SpaceX has been truly innovative in several key areas, launch and large constellation broadband internet — two things people have long dreamed of but have been tried and failed before,” Weeden said. “SpaceX has managed to make them a reality. In many other industries soon after there are breakthroughs, that encourages more competition. And the innovative technology proliferates across multiple companies. But in the case of SpaceX, we haven’t yet seen competitors who have managed to do what they can do.”

That dominant position didn’t come easy. SpaceX was initially locked out of Pentagon launch contracts and had to sue the Air Force to be allowed to compete. It also fought to earn NASA as a customer, and now it is one of the space agency’s most reliable partners.

A good portion of that success stems from Musk himself, who works relentlessly and pushes his teams to as well, attempting to overcome seemingly insurmountable odds. Building rockets that would fly to space and then land safely so that they could be reused is one example, especially as many had told Musk it was impossible. Building a constellation of thousands of satellites was another. Both were accomplished relatively quickly, which is part of the SpaceX ethos.

“You can always go faster than you think you can. Hands down,” Kiko Dontchev, SpaceX’s vice president of launch, said during a recent conference presentation. “There’s always time to gain. There’s always efficiencies to be brought. You think you went fast enough? … You can go faster. Every time my team is like, ‘Dude, we can’t go faster.’ You’re like, ‘Yes, you can.’ Move the goal posts. You’ll be surprised what happens when you challenge people.”

SpaceX has also thrived operating under what are known as fixed-priced contracts, where the contractor must eat any cost overruns. Traditionally, big Pentagon contracts operated under “cost-plus” contracts, allowing companies to be reimbursed if they went over their bid. That, critics have argued, has stifled innovation and allowed companies to move slowly.

The Space Force is also looking to SpaceX and its Starship, which, once flying, will be able to lift enormous amounts of mass to orbit. And it has praised SpaceX for keeping its Starlink constellation online even while Russian jammers were able to interfere with other networks.

“The quality of the link is excellent,” Ukraine’s minister for digital transformation, Mykhailo Fedorov, told The Post last year. “We are using thousands — in the area of thousands — of terminals, with new shipments arriving every other day.”
