Space Force scrambles as Elon Musk's SpaceX retires its major rocket

That presents a headache for the US Space Force, POLITICO reports .

The Space Force has said it's open to eventually using SpaceX's Starship.

But there are engineering challenges to overcome.

SpaceX's plans to retire its most popular rocket could jeopardize the United States' ability to launch military satellites — a plight compounded by the Pentagon's dependence on Elon Musk's company.

SpaceX is by far the dominant player in the rocket business and indispensable to the military, dwarfing competitors and accounting for 85% of US launches in 2025.

The company is phasing out its Falcon 9 rocket to make way for Starship, a massive new vehicle that SpaceX says will be more efficient and profitable, but which many military satellites aren't designed to fit.

The situation leaves the Space Force in a launch crunch that could affect the military's ability to put its advanced satellites in orbit — and on time.

The Pentagon has few alternatives to ferry its equipment, and SpaceX's competitors are likely years away from being able to offer comparable services, reports POLITICO, which — like Business Insider — is part of the Axel Springer Global Reporters Network.

"Everybody's having problems, so the Space Force is freaking out a little bit about launch," one former Space Force official, who, like others, was granted anonymity to discuss the sensitive issue.

It also highlights the scale of Musk's company's footprint and the way its business decisions can affect the security of countries including the United States.

From the battlefield in Ukraine, where Kyiv is dependent on his Starlink satellite internet service, to cutting-edge artificial intelligence and SpaceX's stranglehold over the pathways to orbit, the world's first trillionaire has a direct hand in the technology that will shape the future.

The Space Force recently tried to book rides for three future satellite missions, but SpaceX declined to offer its services, according to two people familiar with the missions.
