Starlink vs. OneWeb vs. Kuiper: The Mega-Constellation Wars Explained

The race to deliver broadband internet from low Earth orbit is the defining infrastructure competition of the 2020s. Three mega-constellations, SpaceX Starlink, Eutelsat OneWeb, and Amazon Project Kuiper (now Amazon Leo), are deploying thousands of satellites to connect the unconnected and challenge terrestrial telecom incumbents. Each takes a fundamentally different approach to technology, business model, and market strategy.

This analysis compares all three across the dimensions that matter: constellation architecture, coverage, performance, pricing, partnerships, government contracts, and competitive positioning. The data is current as of March 2026.

Constellation Architecture: Scale vs. Strategy

The three constellations differ dramatically in scale, orbital altitude, and design philosophy.

SpaceX Starlink

Starlink is, by every measure, the largest satellite constellation ever built. As of March 2026, SpaceX operates approximately 7,000 active Starlink satellites across multiple orbital shells, with FCC authorization for up to 12,000 in its first-generation constellation and an additional 30,000 in its Gen2 constellation. Starlink satellites orbit at altitudes between 340 km and 570 km, with the majority clustered around 550 km in the first-generation shell.

Each Starlink v2 Mini satellite weighs approximately 800 kg and features a phased-array antenna system, inter-satellite laser links (now deployed across most of the constellation), and a Hall-effect thruster for orbit raising and station-keeping. The laser links are a critical differentiator: they allow traffic to hop between satellites without touching the ground, reducing latency for long-distance routes and enabling service over oceans and polar regions without ground stations.

SpaceX launches Starlink satellites on its own Falcon 9 rockets, giving it a vertically integrated cost advantage that no competitor can replicate. The marginal cost of adding satellites is dramatically lower when you own the launch vehicle and are already flying at a cadence of roughly one mission every 2.5 days.

Eutelsat OneWeb

OneWeb's constellation is fully deployed at 648 satellites in a 1,200 km polar orbit. Following OneWeb's 2020 bankruptcy and subsequent rescue by a consortium led by the UK government and Bharti Airtel, the company merged with Eutelsat in 2023 to create Eutelsat Group, combining OneWeb's LEO constellation with Eutelsat's geostationary fleet.

OneWeb's architecture prioritizes global coverage from day one with fewer satellites by operating at a higher altitude where each satellite covers a larger ground footprint. The trade-off is higher latency (approximately 50–70 ms compared to Starlink's 20–40 ms) and lower per-user capacity. OneWeb satellites weigh about 150 kg each and were manufactured by Airbus OneWeb Satellites at a facility in Florida.

The merger with Eutelsat created an interesting multi-orbit strategy. Enterprise and government customers can be served by GEO satellites for broadcast and backhauling, while LEO satellites handle latency-sensitive applications. This hybrid approach is unique among the three competitors.

Amazon Project Kuiper

Amazon's Kuiper constellation received FCC authorization for 3,236 satellites across three orbital shells at 590 km, 610 km, and 630 km. After years of development, Kuiper launched its first production satellites in late 2025 and is now in the early deployment phase, with approximately 100–150 satellites in orbit as of March 2026. Amazon must deploy at least half its constellation by July 2026 to meet its FCC license deadline, a timeline the company has acknowledged it will not meet and is seeking an extension for.

Kuiper satellites are manufactured at Amazon's purpose-built facility in Kirkland, Washington. Each satellite features a Ka-band phased-array antenna, custom-designed ASIC chips for signal processing, and an advanced propulsion system. Amazon has invested over $10 billion in the program, making it one of the largest private infrastructure investments in space history.

Amazon has secured launch capacity across multiple providers, including United Launch Alliance (Atlas V and Vulcan), Arianespace (Ariane 6), and Blue Origin (New Glenn), rather than relying on a single launch provider. This diversified approach reduces single-point-of-failure risk but increases coordination complexity and potentially cost.

Coverage and Performance

Starlink offers active commercial service in 75+ countries, covering most of North America, Europe, Australia, parts of South America, and expanding into Africa and Asia. Its dense satellite constellation delivers the best consumer performance in the industry, with real-world download speeds of 100–300 Mbps and latency of 20–40 ms in areas with sufficient ground station coverage. Starlink's laser inter-satellite links have been transformative for coverage over oceans, in polar regions, and in areas where ground station placement is politically or geographically difficult.

OneWeb provides global coverage including polar regions, a key advantage for maritime, aviation, and government customers operating at high latitudes. Its 1,200 km polar orbit delivers full Earth coverage with 648 satellites, though with higher latency and lower per-user throughput than Starlink. OneWeb does not serve individual consumers; its distribution model relies on telecom partners and service providers who integrate OneWeb capacity into their own offerings. Major distribution partners include BT, Hughes, AT&T, and Airtel.

Kuiper has not yet launched commercial service. Amazon has demonstrated download speeds of up to 400 Mbps in testing, which, if achieved at scale, would be competitive with or superior to Starlink. Amazon plans to leverage its existing logistics and retail infrastructure for terminal distribution, potentially offering Kuiper terminals through Amazon.com and Whole Foods locations. The company has also indicated it will bundle Kuiper service with Amazon Prime, creating a distribution advantage no other constellation operator possesses.

Pricing and Business Models

The three constellations target different markets with different economics.

Starlink operates across consumer, business, maritime, aviation, and government tiers. Consumer service starts at $120/month with a $499 terminal. Starlink Business offers higher throughput at $250/month. Starlink Maritime and Aviation products serve the mobility market at premium price points ($5,000–$25,000/month for maritime). The consumer business provides volume, while enterprise and mobility segments drive margin. Starlink generated an estimated $6.6 billion in revenue in 2025, making it the primary revenue driver for SpaceX.

OneWeb/Eutelsat operates exclusively in the B2B and government segment. It does not sell directly to consumers. Revenue comes through distribution agreements with telecom operators, managed service contracts with enterprise customers, and government/defense contracts. The merged Eutelsat Group reported approximately €1.2 billion in annual revenue, though only a portion comes from OneWeb's LEO services. The B2B model avoids the capital-intensive consumer terminal subsidy problem but limits total addressable market.

Kuiper has not yet published commercial pricing. Amazon CEO Andy Jassy has indicated the company targets a consumer price point of approximately $100/month or less, undercutting Starlink. Amazon's willingness to absorb losses in the early years (a strategy it has employed across retail, AWS, and Alexa) suggests it may price aggressively to capture market share. The potential integration with AWS ground station infrastructure creates enterprise synergies that neither Starlink nor OneWeb can match in the cloud services domain.

Partnerships and Distribution

Each constellation operator has built a distinct partnership ecosystem.

Starlink has partnerships with major airlines (including Hawaiian Airlines and JSX for in-flight Wi-Fi), cruise lines, and enterprise connectivity providers. T-Mobile's direct-to-cell partnership with Starlink is particularly significant: it enables standard smartphones to connect to Starlink satellites for texting and eventually voice and data in areas without cell tower coverage. This partnership, if it scales, could make Starlink infrastructure for every mobile carrier, not just a standalone service.

OneWeb/Eutelsat has deep partnerships in the telecom and government sectors. Distribution agreements with BT (UK), AT&T, Hughes Network Systems, Bharti Airtel (India), and SoftBank (Japan) give it a global enterprise reach. The UK government's ownership stake (now through Eutelsat) provides preferential positioning for British military and government connectivity requirements.

Kuiper leverages Amazon's unmatched ecosystem. AWS integration means enterprise customers can potentially route satellite data directly to AWS cloud regions. Amazon has announced partnerships with Verizon (to extend its 4G/5G coverage to rural areas via Kuiper backhaul) and with telecom providers in underserved markets. Amazon's retail logistics network provides an unparalleled distribution channel for consumer terminals.

Military and Government Use

All three constellations have significant government and military dimensions.

Starlink has become a de facto military communications asset. Its use by Ukrainian forces since 2022 demonstrated the operational value of LEO broadband in contested environments. SpaceX has developed Starshield, a dedicated government and military variant with enhanced encryption, anti-jam features, and secure ground infrastructure. The U.S. Space Force, Army, and intelligence community have multiple contracts with SpaceX for Starshield services. Starlink's demonstrated resilience against Russian electronic warfare has made it the benchmark for military satellite communications.

OneWeb/Eutelsat has contracts with the UK Ministry of Defence, the U.S. Air Force, and NATO allies. The UK government's strategic investment in OneWeb was partly motivated by the desire for a sovereign LEO communications capability post-Brexit. OneWeb's polar orbit coverage is particularly valuable for military operations in the Arctic, an increasingly contested theater.

Kuiper is pursuing government contracts, though its later deployment timeline means it has not yet secured the large-scale military adoption that Starlink has achieved. Amazon Web Services' existing position as the largest cloud provider to the U.S. intelligence community (via the C2E contract and its predecessor) provides a natural entry point for Kuiper in the defense and intelligence market. If Kuiper can offer integrated satellite-to-cloud pipelines for government data, it could carve out a distinct defense niche.

Who Is Winning, and Why

As of March 2026, Starlink is winning decisively on every operational metric: satellite count, coverage, subscribers, revenue, and demonstrated military capability. SpaceX's vertical integration (designing, manufacturing, and launching its own satellites) creates a structural cost advantage that neither OneWeb nor Kuiper can replicate. Starlink has over 4 million subscribers globally, generates billions in recurring revenue, and has proven its technology in the most demanding real-world conditions imaginable.

But this is not a winner-take-all market. Several factors prevent Starlink from capturing the entire market:

• Sovereignty concerns. Many governments, particularly in Europe, India, and China, are reluctant to depend on a single U.S. company for critical communications infrastructure. OneWeb's European ownership and Kuiper's partnerships with non-SpaceX entities provide alternatives for sovereignty-conscious buyers.
• Enterprise preferences. Large enterprises and governments often prefer multi-vendor strategies. OneWeb's B2B model and Eutelsat's decades of enterprise satellite experience make it the natural second source for organizations that do not want single-provider risk.
• Amazon's distribution muscle. Amazon's ability to bundle Kuiper with Prime, sell terminals through its retail channel, and integrate with AWS creates a consumer and enterprise distribution advantage that could erode Starlink's market share once Kuiper reaches operational scale.
• Capacity constraints. Even with 7,000 satellites, Starlink faces capacity limitations in dense urban areas. A market with three or more mega-constellations may actually serve users better than a monopoly, as spectrum and orbital resources are shared across providers.

The Likely Outcome

The mega-constellation market is likely to consolidate into a structure similar to the mobile wireless market: 2–3 major providers with differentiated positioning. Starlink will be the market leader with the largest consumer base. Eutelsat/OneWeb will serve enterprise and government customers who want a non-SpaceX provider. Kuiper, if Amazon executes on deployment, will compete on price and ecosystem integration, potentially capturing significant share in markets where Amazon has strong existing relationships.

The wild card is China. The SatNet/GuoWang constellation (13,000 planned satellites) and the G60 constellation backed by the Shanghai government represent a state-backed competitive threat that could fragment the global market into Western and Chinese blocs. China's constellations will serve the Chinese domestic market and Belt and Road partner nations, potentially limiting the addressable market for Western providers.

What to Watch in 2026

• Kuiper deployment pace. Can Amazon ramp from 100 to 1,000+ satellites by year-end? The FCC deployment deadline creates real urgency.
• Starlink Gen2. The transition to larger Gen2 satellites launched on Starship will dramatically increase per-satellite capacity. First Gen2 launches on Starship could redefine the economics of the entire industry.
• OneWeb Gen2 plans. Eutelsat has discussed a second-generation LEO constellation with inter-satellite links and higher capacity. Watch for concrete deployment commitments.
• Direct-to-cell. Starlink's T-Mobile partnership is the first mover, but AST SpaceMobile and Kuiper have similar ambitions. The first constellation to offer reliable direct-to-cell service at scale wins a massive market.
• Government contract awards. U.S. DoD and NATO procurement decisions for LEO SATCOM will shape revenue trajectories for years.
