The SPACEPORT Act amends chapter 511 of Title 51 to refocus the federal grant program for space transportation infrastructure. It broadens which local entities qualify as 'public agencies', imposes a 90 percent federal share limit for project grants (subject to a national-interest waiver), directs the Secretary of Transportation to develop selection criteria and consult key agencies, requires a multi-part report on demand and funding options, and caps annual appropriations for the program at $10 million.
This is a narrowly targeted statutory rewrite: it moves the grant program from an undefined federal share toward a standard 90/10 financing expectation, tightens program governance through DOT-led criteria and mandatory consultation with Defense, NASA, and Commerce, and forces an evidence-based assessment of U.S. civil, national security, and commercial space transportation needs. For state and local infrastructure planners, launch operators, and federal agencies, the bill reshapes how spaceport upgrades compete for federal dollars and how those projects are evaluated and funded.
At a Glance
What It Does
The bill amends the space transportation infrastructure grant chapter to (1) redefine eligible 'public agency' recipients, (2) limit federal grants to no more than 90% of a project's cost unless waived for national interest, (3) require the Secretary of Transportation to set selection criteria and consult other agencies, (4) mandate a substantive DOT report on demand and funding options, and (5) authorize up to $10 million per year for the program.
Who It Affects
State and local governments, airport authorities, and tax-supported organizations that would seek federal funding for spaceport or launch-range projects; commercial launch providers and launch-range operators that rely on upgraded infrastructure; and federal agencies—DOT, DOD, NASA, and Commerce—tasked with consultation, evaluation, and reporting.
Why It Matters
The act establishes a clearer financing expectation for federal support (90% cap), brings explicit interagency coordination into project selection, and requires a forward-looking assessment of U.S. and international launch capacity and funding models—shaping which projects get built and how public and private partners structure deals.

What This Bill Actually Does
The bill rewrites the statutory grant program that supports space launch and re-entry infrastructure. It first expands the legal definition of who may receive grants to include airport authorities and tax-supported organizations, which potentially brings more local entities into eligibility.
It then sets a default federal cost share limit: grants may not exceed 90 percent of a project's total cost, creating a baseline expectation that nonfederal partners will cover at least 10 percent. The Secretary of Transportation retains discretion to waive that cap when the Secretary determines a higher federal share is in the national interest.
On project selection and evaluation, the bill removes the previous, narrower single‑phrase framing of federal needs and replaces it with an explicit set of considerations: civil, national security, and commercial space transportation needs. The Secretary of Transportation must develop detailed selection criteria tied to those considerations and is directed to consult with the Secretary of Defense, the NASA Administrator, the Secretary of Commerce, and other appropriate agency heads about how projects affect government launch ranges and national needs.
That puts DOT at the center of evaluation while formally building interagency views into decisions.The legislation also forces an evidence-driven planning exercise. Within two years, DOT must deliver to Congress a multi-part report assessing demand for space transportation services across civil, national security, commercial, and international markets; offering legislative, regulatory, and policy recommendations to support resilient capabilities; examining long-term funding options for infrastructure; and surveying international capacity with recommendations for U.S. competitiveness and an international network.
DOT must update that report six years after enactment and then every four years thereafter. Finally, the bill sets an annual authorization of up to $10 million for grants and adjusts chapter headings and statutory cross-references to reflect the retooled program.
The Five Things You Need to Know
The bill sets a default federal grant share cap at 90% of a project's total cost and allows the Secretary of Transportation to waive that cap if doing so serves the national interest.
It broadens the definition of 'public agency' to explicitly include airport authorities and tax-support organizations as eligible recipients.
The Secretary of Transportation must develop specific project evaluation and selection criteria and consult the Defense, NASA, and Commerce departments on national-security and launch-range impacts.
DOT must submit a report within two years that evaluates civil, national security, commercial, and international demand; recommends policy and funding options; and assessess international capabilities, with an update due six years after enactment and every four years after that.
The act authorizes up to $10,000,000 per fiscal year to make grants under the modernized chapter.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Short title
Establishes the Act's short names: 'Spaceport Project Opportunities for Resilient Transportation Act' and the 'SPACEPORT Act.' This is purely nominal but signals congressional intent to frame the statute around resilient transportation and project opportunities.
Expanded definition of 'public agency'
Amends 51 U.S.C. 51101(5) to make 'public agency' include a State or agency of a State, political subdivisions, airport authorities, and tax-support organizations. Practically, this widens the pool of local entities that can apply for grants—bringing airport authorities and certain publicly funded organizations into explicit eligibility and changing who can lead or receive project funds.
Federal share limit and waiver authority
Rewrites the limitations in 51 U.S.C. 51102(b) to cap federal project grants at 90 percent of total project cost but grants the Secretary a waiver where exceeding 90 percent is determined to be in the national interest. That creates a presumption of a 10 percent nonfederal match while preserving flexibility for exceptional circumstances—military urgency, strategic national projects, or other priorities the Secretary deems critical.
Selection criteria and required interagency consultation
Overhauls 51 U.S.C. 51103(b) by (1) recasting the foundational evaluation focus from the general 'Government space transportation needs' to explicit civil, national security, and commercial needs; (2) replacing vague language about 'contributions' with 'support'; (3) sharpening the assessment of impacts on launch and re-entry operations; and (4) requiring DOT to craft specific selection criteria. It also mandates that DOT consult DOD, NASA, Commerce, and other agencies regarding the civil, national security, and launch-range impact elements—embedding interagency input into project selection rather than leaving it ad hoc.
Statutory report requirement and cadence
Directs the Secretary of Transportation, in consultation with DOD, NASA, Commerce, and other relevant agencies, to produce a comprehensive report within two years assessing domestic and international demand, policy and regulatory recommendations, long-term funding options for infrastructure, and an international capability assessment with competitiveness recommendations. The bill requires an update six years after enactment and then periodic updates every four years, creating a recurring statutory analytical obligation to inform policy and funding decisions.
Annual authorization
Amends 51 U.S.C. 51105 to authorize up to $10,000,000 per fiscal year for the grant program. This sets an explicit ceiling for annual appropriations, a modest sum relative to large infrastructure programs, which will affect the scale and number of projects that can be supported at the federal level.
Technical amendments
Updates the chapter heading to 'Space Transportation Infrastructure Modernization Grants' and corrects the table of chapters to reflect the new name. These are non-substantive editorial changes that align statutory headings with the program changes.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Airport authorities and tax-supported local organizations — now explicitly eligible as 'public agencies,' they can apply directly for grants and lead infrastructure projects that support launch operations.
- State and local governments seeking to upgrade launch facilities — the 90% federal share cap still makes federal dollars attractive for capital-intensive projects while leaving room for local matching and public-private cost-sharing structures.
- Commercial launch providers and launch-range operators — a clearer federal program with DOT-developed selection criteria and interagency consultation can improve planning certainty and create opportunities for infrastructure investments that expand commercial launch capacity.
- Federal agencies with launch interests (DOD, NASA, Commerce) — mandatory consultation gives these agencies a formal voice in project selection and alignment of infrastructure investments with civil and national security needs.
Who Bears the Cost
- Nonfederal project partners (states, localities, private partners) — the 90% cap codifies an expectation of at least a 10% local or private match, increasing the need for local funding commitments or private investment.
- Department of Transportation — DOT must develop selection criteria, manage interagency consultations, and produce recurring, detailed reports, adding administrative and analytical responsibilities without an explicit new funding stream for those tasks.
- Congressional appropriations process — the $10 million annual authorization is a statutory ceiling; appropriators must decide how to allocate limited funds across competing projects and may find demand exceeds the authorized level.
- Smaller or under-resourced jurisdictions — while newly eligible, jurisdictions without the ability to provide matching funds or to meet DOT's future criteria may struggle to win grants, shifting benefits toward better-capitalized applicants.
Key Issues
The Core Tension
The bill tries to balance stronger federal stewardship of spaceport investments and interagency alignment with fiscal restraint and local cost-sharing: it seeks to prioritize national security and commercial competitiveness while limiting federal exposure, but that combination forces trade-offs in which projects get funded, who can realistically participate, and how discretionary the Secretary’s waiver authority becomes.
The bill walks a line between creating a predictable federal posture and constraining program scale. The 90 percent cap offers a uniform financing signal that encourages nonfederal contribution but may undercut projects in economically disadvantaged regions that rely on higher federal cost shares.
The national-interest waiver is a safety valve, but it vests significant discretion in the Secretary of Transportation without spelling out objective waiver criteria, which could invite political or interagency tensions when invoked.
The statutory requirement that DOT consult DOD, NASA, and Commerce on selection factors and launch-range impacts improves coordination but also introduces potential conflicts among differing agency priorities—commercial growth, national security redundancy, and civil-science access do not always align. Implementing the mandated report and recurring updates will demand robust metrics and data-sharing across agencies; absent clear analytic standards, the report risks being either too general to guide investment choices or too granular to resolve inevitable trade-offs.
Finally, the $10 million annual authorization sets a modest budgetary envelope that may substantially limit the program’s ability to address large-capital needs, leaving states and private actors to bridge the remainder or shelve projects.
