Starlink

What it is

Starlink is SpaceX's low-Earth-orbit (LEO) broadband satellite network, owned and operated by SpaceX Services Inc., a subsidiary of US-based Space Exploration Technologies Corp. The US Federal Communications Commission (FCC) licenses its spectrum and orbital slots; the International Telecommunication Union (ITU) governs international coordination. The constellation operates at altitudes of roughly 480 to 550 km, far below traditional geostationary satellites at 35,786 km. That lower altitude reduces round-trip latency to 25 to 60 milliseconds, making the service viable for real-time applications. Two main hardware generations are in service as of mid-2026: Gen 1 (versions v1.0 and v1.5) and Gen 2 (V2 Mini and full-size V2), with Gen 2 satellites providing roughly 4 to 20 times the per-satellite throughput of their predecessors.

History

SpaceX launched the first two Starlink test satellites in February 2018. The first major operational batch of 60 satellites flew in May 2019. The FCC authorized 12,000 satellites across multiple orbital shells in 2018, with further approvals for 30,000 Gen 2 satellites beginning in 2022. In January 2026, the FCC granted an additional 7,500 Gen 2 authorizations, raising the total approved fleet to 15,000 and expanding permissible frequencies to V-, E-, and W-band. Commercial service launched in October 2020 in the northern US and Canada as a beta, expanding to approximately 160 countries and territories by 2025. Starlink generated roughly US$11.4 billion in revenue in 2025, approximately 61 percent of SpaceX's total revenue that year and a 50 percent year-over-year increase.

Current state

As of early July 2026, roughly 10,413 Starlink satellites have been placed in orbit, with approximately 10,000 simultaneously active, making it by far the world's largest operational satellite constellation. The network crossed 10 million active subscribers in February 2026. SpaceX's stated target is 25 million subscribers by end-2026, adding roughly 52,000 net new users daily. A direct-to-cell product, rebranded as Starlink Mobile, operates with 650 or more dedicated satellites and covered 16 million users by mid-2026. Throughout 2026, SpaceX is lowering approximately 4,400 Gen 1 satellites from 550 km to 480 km altitude, reducing ballistic decay time by more than 80 percent at solar minimum to address FCC and NASA pressure over orbital density. The Starlink Mobile build-out is also driving new carrier partnerships in markets where terrestrial fiber remains uneconomical, and individual missions continue at pace: a Falcon 9 mission in June 2026 added 24 V2 Mini satellites on a booster making its 25th flight.

Relationships

SpaceX controls the full production stack: satellite design and manufacture, launch (primarily Falcon 9), ground station infrastructure, and end-user terminals. Starship is central to the Gen 3 scaling plan. Full V2 and planned V3 satellites are too large for Falcon 9 to carry in volume, so the Starship Flight 12 booster failure directly affects the timeline for Starlink's next capacity phase. The primary rivals are Amazon's Kuiper constellation and China's state-backed SatNet (Guowang), both targeting similar LEO orbital shells. China raised concerns at the United Nations in early 2026 over Starlink's 60 to 70 percent share of all active LEO satellites and over SpaceX's collision avoidance obligations, a dispute central to the broader LEO collision risk problem. Between December 2024 and May 2025, Starlink satellites executed 144,404 collision avoidance maneuvers, per SpaceX's regulatory filings.

What to watch

Starship cadence is the primary variable for Gen 3 scale; a Starship can carry roughly 3 to 4 times more satellite mass than a Falcon 9. ITU rules require SpaceX to have 10 percent of its Gen 2 authorization operational by 2026 to retain spectrum rights, creating a legal floor on launch pace. Spectrum coordination fights with rival constellations at the ITU and within the FCC are intensifying as multiple operators share Ka-, V-, and E-band regimes. The subscriber model faces a structural test as high-income markets approach saturation and SpaceX shifts toward lower-income regions where average revenue per user is materially lower, pressuring the unit economics behind the US$11.4 billion 2025 revenue figure.
