Starlink

Starlink is SpaceX’s broadband constellation and the largest satellite fleet ever flown — by a margin so wide that it accounts for the majority of all active satellites in orbit. It is also the only LEO broadband network operating at meaningful commercial scale, and the benchmark against which every other operator in this directory is measured.

The reason Starlink exists, and the reason its competitors are struggling to match it, is not the satellite. It is the rocket. SpaceX is the only constellation operator that owns its own launch provider, and Falcon 9 reusability collapsed the cost of putting mass into orbit far enough to make a 40,000-satellite network arithmetically plausible. Every strategic advantage Starlink holds traces back to that vertical integration.

How It Got Here

SpaceX announced the constellation in January 2015. The first sixty operational satellites — the v0.9 batch — went up in May 2019, and public beta, marketed with characteristic bluntness as “Better Than Nothing Beta”, opened in October 2020 at $99 a month with a $499 terminal.

The trajectory since has been defined by two curves running in opposite directions: satellites launched, climbing steeply, and cost per satellite, falling. SpaceX has iterated the spacecraft continuously — v1.0, v1.5 with optical inter-satellite links, then the substantially larger V2 Mini — while iterating the terminal to strip cost out of the phased array, historically the most expensive component in any consumer satellite system.

The Constellation

Metric	Position	Source type
Gen1 authorisation (FCC)	4,408 satellites, Ku/Ka-band	Regulatory filing
Gen2 authorisation (FCC)	7,500 of 29,988 requested	Regulatory filing
Satellites launched	>8,000 cumulative	Launch record
Operational in orbit	~7,000 (majority of all active satellites)	Tracking data / estimate
Operational altitude	540–570 km	Regulatory filing
Design life	~5 years — implies continuous replacement	Company statement

The five-year design life is the number most often skipped over, and it is arguably the most important one on the page. A 7,000-satellite constellation on a five-year cycle needs roughly 1,400 replacement satellites launched every year simply to stand still. That is a permanent, structural cost line, not a build-out phase that ends. Any competitor without cheap in-house launch inherits the same treadmill at a far worse unit cost.

Optical inter-satellite links

Laser links between satellites let traffic route through the constellation rather than dropping to a ground station in every hop. This is what makes mid-ocean and polar coverage commercially viable, and it is the capability OneWeb’s first generation conspicuously lacks.

Business Model and Economics

Starlink is a consumer subscription business with high-margin enterprise segments bolted on top. The consumer product is the volume driver and the reputational engine; maritime, aviation and government are where the ARPU is.

• Residential — the base tier, priced regionally, with hardware subsidised or discounted in competitive markets.
• Maritime and aviation — multi-thousand-dollar monthly plans. Airlines including United, Qatar Airways, Air France and Hawaiian have signed for in-flight connectivity, an incumbent market Starlink is taking on price and performance simultaneously.
• Direct-to-cell — a partnership-led model with T-Mobile in the US and carriers including Optus, Rogers, KDDI and One NZ elsewhere. SpaceX supplies the space segment; the carrier owns the customer.
• Starshield — the government and defence variant, including classified work reported for the National Reconnaissance Office. Strategically important and almost entirely opaque.

Scale and revenue

SpaceX is private and does not publish audited accounts, so every revenue figure in circulation is either a company statement or a third-party estimate. Treat them accordingly. The customer base passed 4 million in late 2024 and 5 million during 2025, on company statements. Independent analysts estimated 2024 Starlink revenue in the region of $7–8 billion, and SpaceX has publicly projected materially higher figures for subsequent years.

What is not in dispute is the direction: Starlink long ago overtook the launch business to become the majority of SpaceX revenue, and it is the financial engine underwriting Starship.

Competitive Position

Starlink’s moat is cost per bit delivered, and it is compounding. Owning the launch vehicle removes the single largest cost input a competitor must buy on the open market — frequently from SpaceX itself. Manufacturing satellites at volume drives the unit cost down a learning curve nobody else is far enough along to be riding.

The credible challenge is not another broadband constellation. It is Amazon, which can absorb losses indefinitely and owns a distribution channel — Prime, AWS — that SpaceX cannot replicate. And the credible constraint is not competition at all: it is capacity. Starlink is bandwidth-constrained in dense markets, and adding subscribers in a congested cell degrades the product for everyone already in it. Growth and quality are in direct tension.

Regulation and Risk

• Market access — Starlink must be licensed country by country, and several large markets have been slow, conditional or hostile. Each one is a discrete political negotiation, not a technical rollout.
• Orbital debris and congestion — Starlink conducts a very large number of automated collision-avoidance manoeuvres, and its share of active satellites makes it the central actor in any conjunction debate.
• Astronomy — satellite brightness and radio interference remain an unresolved conflict with ground-based observatories, and a live source of regulatory pressure.
• Key-person and governance risk — SpaceX’s political entanglements are now a commercial variable for a company that sells to governments on both sides of most arguments.
