WASHINGTON, July 25 — Starlink, the satellite internet constellation operated by SpaceX subsidiary Starlink Services, LLC, has quietly become one of the most strategically significant commercial space assets in existence. As of June 2026, the network comprised roughly 10,413 satellites in low Earth orbit, of which about 10,397 were operational — a fleet that accounts for an estimated 75 percent of all active maneuverable satellites in Earth orbit. The constellation now serves more than 12 million subscribers across approximately 160 countries and territories.
The sheer scale of the system signals a shift in the calculus of control over orbital infrastructure. Starlink is no longer just a broadband play; it is a de facto backbone for government and military communications, most visibly in the ongoing Russo-Ukrainian war.
The company’s role in that conflict has underscored the broader stakes: control of satellite connectivity is now a lever of geopolitical influence.
From a Startup to SpaceX’s Biggest Business
SpaceX began launching Starlink satellites in 2019, but the concept of low Earth orbit constellations is far older. The U.S. Strategic Defense Initiative’s “Brilliant Pebbles” program in the mid-1980s first envisioned a LEO satellite network for missile defense. Commercial attempts in the 1990s — Celestri, Iridium, Globalstar, and Teledesic (which proposed 840 satellites) — all struggled.
Iridium and Globalstar filed for bankruptcy; Teledesic wound down after the dot-com bust. The failure of those earlier systems shaped the skepticism that greeted Elon Musk’s 2015 announcement that SpaceX would build its own constellation.
By early 2014, Musk had been in talks with Greg Wyler to build a roughly 700-satellite network called WorldVu. Those discussions collapsed in June 2014. SpaceX then filed an application with the International Telecommunication Union under the name STEAM via Norway, and the connection to today’s Starlink was confirmed in a 2016 Federal Communications Commission filing.
The company trademarked “Starlink” in the United States. At the January 2015 opening of the SpaceX satellite development facility in Redmond, Washington, Musk said the constellation would target capacity to carry up to half of all backhaul communications traffic and as much as 10 percent of local internet traffic in high-density cities.
He also framed Starlink’s positive cash flow as a funding mechanism for SpaceX’s Mars objectives. The financial numbers bear out that ambition. By the end of 2025, Starlink had become SpaceX’s largest business segment, generating $11.4 billion in revenue and $4.4 billion in operating income.
SpaceX had estimated in May 2018 that designing, building, and deploying the constellation would cost at least $10 billion.
Strategic Asset and Orbital Concern
The military utility of Starlink has reshaped the geopolitical conversation around satellite constellations. In the Russo-Ukrainian war, the system provides critical communications for Ukrainian forces. That role has drawn scrutiny from both rival states and international regulators.
Strategically, the constellation gives the United States and its allies a resilient, distributed communications layer that is far harder to disable than traditional geostationary satellites. Yet the same density that makes Starlink valuable also fuels concerns about orbital congestion and astronomy.
The sheer number of satellites — more than 10,000 operational — has prompted discussions among astronomers about light pollution and interference with scientific observations. Space traffic management is becoming a live policy question as the constellation continues to grow. The history of LEO constellations is littered with bankruptcies and abandoned projects.
That Starlink has not only survived but become SpaceX’s dominant revenue stream is itself a fact worth watching. In 2004, Larry Williams, a former vice president of the failed Teledesic project, joined SpaceX as vice president of strategic relations and opened the company’s Washington, D.C., office.
That same June, SpaceX acquired a 10 percent stake in Surrey Satellite Technology Ltd., a British small-satellite manufacturer, before selling it back to EADS Astrium in 2008. The connections between earlier failures and today’s success are not coincidental. What this signals for the broader stakes of space governance is clear: the era of small, niche satellite constellations is over.
Starlink represents a new model — a single commercial system that dominates maneuverable orbital assets, finances interplanetary ambitions, and serves as a strategic hedge for governments. The next 12 months will test whether international rules can keep pace with that reality, or whether orbital congestion and military competition force a reckoning.
