WASHINGTON, D.C. –
SpaceX secured a partial Federal Communications Commission approval on July 18, 2025, allowing the company to expand its next‑generation Starlink satellite constellation by 7,500 satellites, operate much of that fleet at lower altitudes, and use a broader set of radio frequencies – while receiving a time‑limited waiver to exceed current power limits domestically for the purpose of boosting service performance.
The 34‑page FCC order doubles the allowed size of SpaceX’s second‑generation Starlink constellation from 7,500 satellites to 15,000, producing a combined fleet ceiling of 19,400 satellites when added to earlier clearance for first‑generation satellites. The order also authorizes deployments in multiple lower orbital shells and approves use of additional spectrum in many (but not all) bands SpaceX requested. At the same time the commission imposed operational conditions intended to protect incumbent geostationary operators and limited the waiver’s scope to operations within the United States.
Approval details and operational parameters
The commission’s order permits deployment “up to 144 satellites in up to 72 planes in each of the 340km, 345km, 350km, 355km, and 365km orbital shells and by deploying up to 120 satellites in up to 56 planes in the 480km and 485km orbital shells.” The second‑generation satellites may also operate at higher altitudes up to roughly 500km. The decision follows a broader request from SpaceX that initially sought authorization for more than 22,000 satellites; the FCC issued a partial grant instead, emphasizing that it would continue to monitor constellation size, orbital debris risk, and interference as deployments scale.
The FCC granted SpaceX a “time‑limited waiver” to exceed existing limits on equivalent power flux density (EPFD) for the domestic market while the agency continues a rulemaking to potentially revise those EPFD standards. On the waiver the commission said: “We believe that while this rulemaking is ongoing, it is in the public interest to grant SpaceX’s request for waiver to allow it to exceed the EPFD [equivalent power‑flux density] limits, given the benefits to SpaceX’s service and thus American consumers and the continued protection of GSO [geostationary] operators.”
Key regulatory points and figures
- Second‑generation satellite cap: increased from 7,500 to 15,000 (net increase 7,500).
- Total authorized constellation (with first‑gen clearance): up to 19,400 satellites.
- Authorized lower orbital shells: 340-365km (multiple shells at 340, 345, 350, 355, 365km) and select 480-485km shells; continued permission at ~500km for some satellites.
- Waiver: time‑limited; confined to Starlink operations within the United States; conditioned to prevent harmful interference and to comply with any final EPFD rules adopted in the pending FCC rulemaking.
By acting through its satellite licensing authority under the Communications Act, the commission is effectively setting a new benchmark for how large, low‑Earth‑orbit broadband constellations can grow while remaining consistent with U.S. spectrum policy and orbital safety norms.
Spectrum, partnerships and corporate implications
The order clears many of the radio bands SpaceX sought to improve downstream and upstream throughput for Starlink, while leaving other requested bands under further review. The decision also permits SpaceX’s cellular Starlink capability to operate with a swath of 2GHz spectrum that the company acquired from EchoStar for use outside the United States; the FCC continues to review the related spectrum transfer and a proposed 15,000‑satellite constellation intended to employ those holdings. The cellular Starlink offering is already being commercialized in the U.S. through carrier partnerships that include T‑Mobile, a model regulators are watching as satellite‑to‑device services blur traditional lines between satellite and terrestrial networks.
For SpaceX, the authorization affects multiple commercial vectors simultaneously: network capacity and consumer speeds, the company’s commercial relationship with mobile carriers, and the cadence of satellite manufacturing and launch demand. SpaceX plans to launch larger V3 Starlink satellites and intends to use its Starship launch vehicle for those flights; the company has forecast that the first V3 satellites will be launched sometime in 2025. Starship remains in an active flight test program, and the timing and pace of Starship test activity will influence when and how quickly SpaceX can populate the newly authorized shells.
Capacity, competitive dynamics and market reach
Industry observers cited in the record argued the expanded authorization will materially increase Starlink’s capacity in congested U.S. markets and reduce latency by operating satellites closer to Earth. Satellite industry analyst Tim Farrar said he expects the order to support significant capacity growth and subscriber expansion. GlobalHeadlinez is publishing Farrar’s full statement as provided to the record:
“The peak capacity in high demand areas could be as much as five times higher (of course you need to launch enough satellites to deliver that capacity). It should allow for substantial growth in the US customer base, which is already likely closing in on 3 million subscribers. And it will make it far less likely that Starlink encounters any congestion on the network from high levels of aircraft use near hubs, which was an area where Viasat claimed to have an advantage.”
The approval touches direct competitors and incumbent satellite operators that have argued for stricter protections against interference and orbital crowding. The FCC attached conditions requiring SpaceX to cease operations that cause harmful interference and to coordinate with affected operators where necessary, reflecting the agency’s role as an arbiter between new LEO entrants and established geostationary operators that rely on stable interference environments for television, broadband, and mobility services.
Environmental and statutory review
Petitioners asked the commission to require additional environmental study under the National Environmental Policy Act (NEPA) over the atmospheric effects of de‑orbiting satellites. The FCC declined to open a new NEPA review, citing the record and a Government Accountability Office review that “recognized that there was uncertainty surrounding potential effects and that further study would be beneficial,” and concluded petitioners had not submitted new evidence. The commission stated: “The record still does not demonstrate that reentering satellites may impact the human environment.” The order notes SpaceX’s commitment to work with the scientific community on methods to study atmospheric effects of reentering spacecraft debris.
That stance keeps the FCC aligned with its current categorical exclusion approach to satellite licensing under NEPA, even as the growth of so‑called megaconstellations intensifies debate in Congress, among scientists, and within the agency itself over whether satellite reentries and night‑sky impacts should trigger more formal environmental review.
Operational conditions and next procedural steps
The FCC’s grant is explicitly conditional. Key operational constraints in the order include:
- Restrictions to prevent harmful radio interference and requirements to coordinate with geostationary satellite operators when necessary.
- A waiver that applies only to operations within the United States and that remains contingent on the completion of the FCC’s pending EPFD rulemaking and any rules adopted therein.
- Continued regulatory review of spectrum transfers and of the proposed constellation intended to use EchoStar‑acquired spectrum outside U.S. jurisdiction.
The practical commercial effect for SpaceX is immediate regulatory clearance to proceed with manufacturing and launch planning for the 15,000‑satellite second‑generation cap, subject to the company’s ability to schedule and execute launches and to comply with the FCC’s operational conditions. For policymakers, the order underscores how the commission is using case‑by‑case licensing, EPFD waivers, and ongoing rulemakings to shape the trajectory of satellite broadband and direct‑to‑device markets under the broader U.S. communications law framework administered by the Federal Communications Commission.
As other companies advance rival constellations and terrestrial carriers explore hybrid satellite‑cellular offerings, this decision will serve as a reference point for future licensing fights over spectrum access, orbital slots, and the balance between rapid deployment and environmental and safety concerns.
