How a Spaceport Gets Licensed: FAA Part 420, the Five-Year Licence and the Hunt for New Sites
Spaceport licensing explained: how the FAA licenses launch sites under Part 420, what the five-year licence allows and why Washington wants new spaceports.
Most discussion of US launch regulation is about rockets. The ground they leave from is regulated too, and the rules for it explain a lot about why the United States has many licensed spaceports but only a handful of busy ones.
This piece explains how a spaceport gets licensed by the Federal Aviation Administration, what the licence does and does not allow, and why the federal government is now asking where to build the next generation of launch sites. For the vehicle side, see our guide to FAA Part 450 launch licensing.
The legal basis
The Commercial Space Launch Act, now chapter 509 of title 51 of the US Code, requires a licence “for a person to launch a launch vehicle or to operate a launch site or reentry site” in the United States, and for US citizens and companies doing the same abroad. That is 51 U.S.C. 50904(a). Under section 50905(a), the FAA must decide “not later than 180 days after accepting an application”, and must tell the applicant of any pending issue if it has not decided within 120 days.
The detailed rules are in 14 CFR Part 420, “License to Operate a Launch Site”, with Part 433 covering re-entry sites and Part 413 setting out the application process. Part 420 does not apply to a site that only supports amateur rocket activities, which we covered in our piece on amateur rocket laws.
In practice the 180-day clock is the end of the process, not the start. The FAA’s own Spaceport Licensing Primer warns that the pre-application consultation period “can be extensive” and, in the FAA’s experience, takes many months and sometimes years, and FAA rules require a prospective applicant to consult the agency before applying.
What the FAA reviews
Section 420.17 lists the bases for a licence. In plain terms, the FAA must be satisfied on six points.
The application is complete. Section 420.15 requires the site layout, the launch points, the types of rocket each will support, the planned launch directions and the operational date. Applicants must also disclose foreign ownership, including any foreign interest of 10 per cent or more in a corporation.
The environmental review is done. The FAA must complete its review under the National Environmental Policy Act before issuing a licence. The applicant supplies the information and, when directed, prepares an Environmental Assessment under FAA oversight or pays for an Environmental Impact Statement by an FAA-selected contractor. The primer describes environmental work as one of the four hardest parts of the process.
The location is safe. This is the heart of Part 420. Under section 420.19, an applicant must show that for each launch point “at least one type of expendable or reusable launch vehicle can be flown from the launch point safely”, meaning with an estimated risk to the public of no more than 0.0001 expected casualties (written in the rule as 1 x 10-4). Rockets are grouped by type and, for orbital vehicles, by weight class, and the site must be large enough to contain the debris from a failure of the largest vehicle planned. A site for an unproven rocket needs a “clear and convincing demonstration” of equivalent safety.
Explosives are sited properly. The applicant needs an explosive site plan showing every hazardous facility and the distances between them and public areas, under sections 420.63 to 420.69.
The airspace and sea lanes are agreed. Section 420.31 requires agreements with the local US Coast Guard district, so that notices to mariners are issued before launches, and with the FAA air traffic control office for the airspace launches will pass through. Sites on a federal launch range can use the range’s existing agreements.
National interests are not harmed. The FAA must find that issuing the licence “would not jeopardize foreign policy or national security interests of the United States”.
What the licence allows, and for how long
A licence to operate a launch site lets the operator offer its site to launch companies for the vehicle types and weight classes assessed in the application. Under section 420.43 it “remains in effect for five years from the date of issuance” and is renewable. The FAA’s directory shows how this works over time: Space Florida’s Launch Complex 46 licence, first issued in 2010, records renewals in 2015, 2020 and 2025.
The licence comes with continuing duties. The operator must control public access, schedule customers so their operations do not endanger each other, notify local officials and neighbouring landowners at least two days before a flight, keep a mishap plan and retain records for three years. Section 420.41(c) adds that the licence does not “confer any proprietary, property, or exclusive right in the use of airspace or outer space”.
What a spaceport licence does not do
It does not authorise a single launch. Every launch from a licensed site still needs a vehicle operator licence under Part 450, and the vehicle operator must coordinate with the site operator on mishap response.
Not every launch site needs a Part 420 licence either. The federal ranges at Cape Canaveral, Kennedy Space Center, Vandenberg and Wallops are government sites. And a company launching only its own rockets from its own land can operate what the FAA’s directory calls a “Private Licensed Exclusive Use Site”, as SpaceX does at Boca Chica and Blue Origin does in West Texas. In those cases the site’s safety is handled within the vehicle licence: section 450.183 requires an operator launching from “a site exclusive to its own use” to meet Part 420’s explosive siting rules. The environmental reviews for Starbase, discussed in our article on the Starship environmental review, are reviews of SpaceX’s vehicle licence, not of a spaceport licence.
Why so many licensed spaceports see so few launches
The FAA’s spaceports by state directory, which relies on information supplied by the spaceports themselves, lists FAA-licensed sites from Alaska to Virginia. Many are at airports and licensed for horizontal launch, where a rocket is carried aloft by an aircraft, at places such as Houston, Midland, Jacksonville and Colorado. Others, like the Pacific Spaceport Complex Alaska on Kodiak Island, support small vertical rockets.
The primer is candid about why licences do not turn into launches. It names four “notable challenges”: stakeholder engagement, co-location with an airport, environmental issues and airspace integration. It quotes an FAA licensing team member describing “one spaceport license that took six years”, mainly because of concerns from two nearby airports. It also says a smaller operational spaceport, averaging two launches a year, faces annual costs of between $10 million and $20 million before labour.
Camden: when a licence is not enough
Spaceport Camden in Georgia is the clearest example. The FAA issued Camden County a launch site operator licence on 20 December 2021 for up to 12 small-rocket launches a year. A local referendum was then held on the county’s plan to buy the land, and in March 2022 voters rejected it. On 7 February 2023 the Supreme Court of Georgia unanimously upheld the referendum, holding that the county was not an elector and could not contest it, as Georgia Public Broadcasting reported.
The federal licence survived; the project did not. The FAA’s own August 2026 notice says local pushback in 2022 ended site development. The FAA’s directory still lists the licence, with an expiry date of 20 December 2026. The lesson for developers is that Part 420 answers a federal safety question. It does not deliver land, local consent or customers.
The push for new spaceports
On 25 August 2026 the FAA published a request for information on siting new spaceports (91 FR 54909). It says the United States carried out 217 of the 329 launches worldwide in 2025, that Cape Canaveral, Kennedy and Vandenberg together account for 83 per cent of US launches, and that the FAA expects “10,000 FAA-licensed launches and reentries a year by 2035”. It ties the exercise to Executive Order 14369 of 18 December 2025 and to the 2026 National Space Transportation Policy, which calls for ranges able to support “more than 1,000 launches and reentries every year” by 2030.
The questions are revealing. The FAA asks “Why are existing commercial spaceports underutilized?”, what Part 420 changes would help a new site, and what people think of earlier proposals, including Space Florida’s Shiloh site, Camden, a Puerto Rico spaceport and launches from converted oil rigs. It also asks how to design “critical space launch corridors”, a term the FAA says it does not currently use. Comments were requested by 26 October 2026.
The RFI sits alongside two other proposals that would change spaceport licensing. The FAA’s July 2026 proposal to use the Secretary of Transportation’s waiver power to set aside requirements of 13 laws, including NEPA, would apply to launch and re-entry site licences as well as vehicle licences, and its October 2026 package of Part 450 changes is covered in our piece on the FAA’s proposed rules.
What I would watch
The first is Camden’s licence. It expires on 20 December 2026. Whether the county seeks renewal, and whether the FAA treats the site as live after the RFI listed it as a “previously proposed” spaceport, will show how the agency handles licences that outlive their projects.
The second is what the Department of Transportation does with the RFI. The notice says it may use responses to identify and characterise potential sites. A federal shortlist of preferred locations would be new; until now, as the notice itself says, the Department “has not been involved in selecting or developing new spaceports”.
The third is the waiver rule. If NEPA review can be waived for site licences, the slowest step in the Part 420 process could disappear, but any final rule is likely to be challenged in court, and the risk of litigation is itself a planning cost for developers.
The fourth is the corridor concept. Airspace, not land, may turn out to be the real limit on new spaceports, and priority corridors would decide which sites can launch often enough to pay their way.
Questions people actually ask
Do you need a licence to operate a spaceport in the US?
Yes. Under 51 U.S.C. 50904, a licence is required to operate a launch site or re-entry site in the United States. The FAA issues launch site operator licences under 14 CFR Part 420 and re-entry site licences under Part 433. Federal ranges, and private sites used only by their owner for its own launches, are handled differently.
How long does an FAA spaceport licence last?
Five years. Under 14 CFR 420.43, a licence to operate a launch site remains in effect for five years from issue unless surrendered, suspended or revoked, and it can be renewed on application.
How long does it take to get a spaceport licence?
The statute requires the FAA to decide within 180 days of accepting a complete application, but pre-application consultation and environmental review usually take much longer. The FAA’s Spaceport Licensing Primer says pre-application work can take many months or even years and describes one licence that took six years.
Does a spaceport licence allow rocket launches?
No. A launch site operator licence lets the operator offer the site to launch companies. Each launch still needs a separate FAA vehicle operator licence under 14 CFR Part 450.
What safety standard does the FAA apply to a spaceport location?
Under 14 CFR 420.19, the applicant must show that at least one type of launch vehicle can be flown safely from each launch point, meaning an estimated risk to the public of no more than 0.0001 expected casualties per flight. The site must also be large enough to contain debris from a failure of the largest vehicle planned.
Why did Spaceport Camden fail?
Camden County, Georgia, received an FAA launch site operator licence on 20 December 2021, but voters rejected the county’s plan to buy the land in a March 2022 referendum, and the Supreme Court of Georgia upheld the referendum on 7 February 2023. The FAA directory lists the licence as expiring on 20 December 2026.
