The Space Force budget stands at about $26 billion in regular appropriations for fiscal year 2026, or about $40 billion when counting funds designated from the July 4, 2025 reconciliation law known as the One Big Beautiful Bill Act. For fiscal year 2027, the Department of the Air Force requested $71.1 billion for the service, comprising roughly $59 billion in base discretionary funding and about $12 billion in a proposed second reconciliation package. As of September 15, 2026, that fiscal year 2027 figure remains an unapproved request before Congress.
The Space Force remains the smallest military service by personnel and base funding, representing about 3.4 percent of total Department of Defense appropriations in fiscal year 2025. Despite that standing among the armed services, its fiscal year 2026 funding exceeded the civilian budget of NASA, which received $24.4 billion in enacted appropriations for the same fiscal year.
The fiscal year 2026 total of about $40 billion funds satellite constellations, ground tracking stations, launch infrastructure, and the personnel who operate military space networks. The money is requested through the Department of the Air Force, research spending dominates the ledger, and classified accounts hide a large share of total space spending.
Space Force Budget Toplines by Fiscal Year
The Space Force budget grew from an initial $15.4 billion request in fiscal year 2021 to an enacted total of about $40 billion in fiscal year 2026 when factoring in reconciliation funds. The initial fiscal year 2021 request did not represent entirely new national defense spending. According to SpacePolicyOnline reporting, that initial request served as a reshuffling of funds previously managed directly by the Air Force.
Congress consistently adjusted early presidential requests before enacting annual defense appropriations. In fiscal year 2022, the White House requested $17.4 billion, and lawmakers enacted an expanded appropriation of $18.0 billion. In fiscal year 2023, the administration sought $24.5 billion, and Congress appropriated $26.3 billion. Growth slowed in fiscal year 2024. The administration requested $30.0 billion, but the fiscal year 2024 defense minibus signed on March 23, 2024, provided about $29 billion, roughly $1 billion below the original request. An Aerospace Corporation Center for Space Policy and Strategy analysis placed enacted fiscal year 2024 funding at approximately $28.9 billion.
Fiscal year 2025 marked the first contraction in the service’s history. The administration requested $29.6 billion according to the Aerospace Corporation, while SpacePolicyOnline recorded the request at $29.4 billion, a difference the two sources do not reconcile. Enacted funding fell to $28.9 billion under Aerospace calculations, or $28.7 billion under the March 2025 full-year continuing resolution reported by SpacePolicyOnline. The Aerospace Corporation identified fiscal year 2025 as the first budget enacted for the Space Force that fell below the prior year, making it the only flat budget year in the service’s existence.
For fiscal year 2026, the administration released a split proposal in June 2025. It requested $26.3 billion in base discretionary appropriations, representing a 9 percent cut of $2.6 billion from fiscal year 2025 enacted levels. The administration offset that reduction by designating $13.8 billion from the One Big Beautiful Bill Act signed on July 4, 2025, producing a combined request of $40.1 billion to $40.2 billion. Final fiscal year 2026 regular appropriations settled at about $26 billion, per SpaceNews. Air & Space Forces Magazine described the enacted total as about $40 billion when counting the reconciliation injection, while the Congressional Research Service listed the enacted total at $31.9 billion.
In April 2026, the Department of the Air Force submitted a fiscal year 2027 request of $71.1 billion, consisting of about $59 billion in base discretionary funds and about $12 billion in a proposed second reconciliation bill. The Congressional Research Service documented the request at $71.3 billion, split between $59.2 billion discretionary and $12.1 billion mandatory funding, while Stars and Stripes reported $71.2 billion. Secretary of the Air Force Troy Meink stated in April 2026 that the department was asking to double the Space Force budget in fiscal year 2027. Then-Chief of Space Operations Gen. Chance Saltzman called the proposal a generational opportunity to position the service against growing threats, as reported by Stars and Stripes. As of September 15, 2026, the fiscal year 2027 figure remains an unapproved request subject to congressional debate.

The Two Funding Channels Inside the Department of the Air Force
The Space Force receives its annual funding through the Department of the Air Force budget, dividing resources between standard discretionary appropriations and multi-year reconciliation measures. The service does not have its own cabinet department. It functions inside the Department of the Air Force in a structure similar to the Marine Corps inside the Department of the Navy.
Standard base funding flows through distinct appropriation accounts established by Congress. The Department of the Air Force submits separate justification books for each major account during the annual budget rollout. Operation and maintenance activities operate under Treasury account 057-3410. Dedicated lines cover research, development, test, and evaluation, equipment procurement, and military personnel. Congress has also established a separate military end strength authorization for the Space Force since the National Defense Authorization Act for Fiscal Year 2022.
A second funding channel emerged in 2025 through budget reconciliation legislation. The One Big Beautiful Bill Act, signed into law on July 4, 2025, provided $153.4 billion in national security funding across fiscal years 2025 through 2029. The statute allocated approximately $21.6 billion, or 14 percent of that national security funding, to the Space Force and broader Department of Defense space initiatives.
Reconciliation spending differs fundamentally from regular appropriations. Reconciliation measures require only a simple majority to clear the Senate rather than the 60 votes required to overcome a filibuster on standard appropriations bills. Reconciliation funds also carry multi-year expenditure authority rather than expiring at the end of a single fiscal year. Senate Armed Services Committee chairman Roger Wicker warned that reconciliation defense spending does not replace the need for real growth in the military base budget. The reliance on reconciliation creates structural uncertainty because future Congresses can alter or decline to renew mandatory allocations.
Breakdown of Major Appropriation Accounts
Research, development, test, and evaluation accounts absorb the majority of the Space Force budget, accounting for nearly two-thirds of the service’s discretionary spending request. Because space operations rely on orbital systems that require years of design, prototyping, and ground testing before launch, development accounts routinely dwarf hardware purchasing and personnel costs.
In the fiscal year 2026 base discretionary request of $26.4 billion, research, development, test, and evaluation stood at $15.5 billion, or approximately 59 percent of the total. Operation and maintenance claimed $6 billion, procurement accounted for $3.4 billion, and military personnel received $1.5 billion.
The fiscal year 2027 discretionary request maintained that spending pattern. The Congressional Research Service calculated the $59.2 billion base request across four primary accounts:
- Research, Development, Test, and Evaluation: $38.4 billion, representing 65 percent of the base discretionary request.
- Procurement: $9.6 billion.
- Operation and Maintenance: $9.3 billion. Stars and Stripes reported this line at $9.1 billion.
- Military Personnel: $1.9 billion, funding pay and benefits for active-duty Guardians. Stars and Stripes cited this line at $1.8 billion.
When adding the proposed fiscal year 2027 reconciliation funds of roughly $12 billion, the distribution shifts toward production contracts. Air & Space Forces Magazine tallied the total proposed fiscal year 2027 accounts at $40.6 billion for research and development, $19 billion for procurement, $9.7 billion for operation and maintenance, and $1.9 billion for personnel. Procurement represents the largest proportional increase, jumping from $3.6 billion in fiscal year 2026, in Air & Space Forces Magazine’s tally, to $19 billion in the 2027 request.
A substantial portion of this capital flows through specialized acquisition agencies. The Space Development Agency accounts for roughly one-fifth of all Space Force procurement and research spending combined. In the fiscal year 2026 request, the Pentagon proposed cutting the agency’s transport layer constellation by 20 percent, reducing it by $340 million from $1.6 billion in fiscal year 2025 to $1.3 billion. House appropriators and the Senate Armed Services Committee moved to restore those funds. Acquisition execution across the rest of the portfolio remains managed by Space Systems Command.
Program Allocations and Classified Space Control
Program allocations in the Space Force budget dedicate $21.6 billion to space control systems in the fiscal year 2027 request, representing approximately 30 percent of the total proposal. Space control lines fund offensive and defensive capabilities designed to protect United States spacecraft and deny space capabilities to adversaries during a conflict.
The vast majority of space control investment sits behind high security classifications. According to a National Security Space Association analysis covered in Defense Daily, $19.4 billion of the $21.6 billion space control request is classified. The unclassified procurement line for space control equals $459 million, which rose by $457 million over the prior year.
Specific hardware buys inside the unclassified ledger include satellite communications electronic warfare systems. The fiscal year 2027 request includes about $450 million to procure additional L3Harris Meadowlands satellite-communications jammers. The Department of the Air Force projected an additional $605 million in Meadowlands procurement across fiscal years 2028 through 2031. On September 14, 2026, Secretary Meink declined to describe the specific capabilities purchased by the classified portion of the space control budget. Details on existing capabilities appear in our analysis of space control programs and operational weapons systems in development.
Beyond space control, the unclassified fiscal year 2027 request details several major hardware investments:
- Missile Warning and Tracking: $6.8 billion.
- Air Moving Target Indicator Satellites: $7.0 billion.
- Satellite Communications: $6.7 billion.
- National Security Space Launch: $2.9 billion for 22 missions (Air & Space Forces Magazine puts the same 22 launches at about $4 billion).
- Proliferated Low Earth Orbit SATCOM: $1.5 billion.
- Space Data Network: $1.5 billion.
- Cyber Warfare Operations: $500 million.
Readers can connect these spending figures to operational responsibilities by reading our guide to the missions assigned to the Space Force.
Classified Accounts and Pass-Through Spending
Classified programs and Department of the Air Force pass-through funding conceal a large fraction of national security space spending from public view. Budget analysts separate the money that the Department of the Air Force controls from funds merely routed through its administrative ledgers.
The largest of these is pass-through funding, historically referred to as non-blue spending. Pass-through funds sit inside the Department of the Air Force budget request but flow directly to other agencies without the Air Force or Space Force exercising control over how the money is spent.
In the fiscal year 2027 request, pass-through spending reached $52.3 billion, marking the first time that non-blue funds exceeded $50 billion in a single year. That total represents 13.4 percent of the Department of the Air Force’s overall $391.1 billion request. Excluding pass-through funds leaves $338.8 billion for genuine service operations, divided between $267.7 billion for the Air Force and $71.1 billion for the Space Force.
At OrbitalIntel, we track Department of the Air Force budget justification books to verify where classified lines and pass-through dollars obscure program spending. For fiscal year 2027, the department requested $74.3 billion in classified spending across its two military branches. The Air Force classified request totaled $56,993,425,000, while the Space Force classified request reached $17,330,381,000. That $17.3 billion classified allocation accounts for nearly one-quarter of the entire $71.1 billion Space Force request.
Military Branch and Civilian Agency Comparisons
The Space Force receives the smallest annual budget of any United States military branch. In fiscal year 2025, the Space Force appropriation accounted for approximately 3.4 percent of total Department of Defense appropriations.
Budget totals depend on the accounting framework applied. Under the Department of Defense Comptroller framework, which incorporates pass-through accounts and proposed reconciliation packages, the Pentagon requested $1.5 trillion in total spending for fiscal year 2027. Under this framing, the Space Force appears at $75.89 billion, placing it ahead of the Marine Corps request of $52.82 billion. In service-specific Department of the Air Force documentation that strips out outside pass-through dollars, the Space Force request stands at $71.1 billion.
The high cost of the Space Force stems from its technical requirements rather than its labor footprint. The service allocates less than 3 percent of its budget request to personnel pay and allowances. Detailed pay rates for Guardians are outlined in our guide to military pay and allowances, while structural differences are detailed in our Space Force versus Air Force comparison.
The Space Force budget has also surpassed the annual budget of the nation’s civilian space agency. For fiscal year 2026, Congress enacted $24.4 billion for NASA, while the Space Force received about $26 billion in regular appropriations and roughly $40 billion when counting reconciliation. For fiscal year 2027, the White House proposed $18.8 billion for NASA, a 23 percent decrease documented in The Planetary Society analysis. The proposed fiscal year 2027 Space Force request of $71.1 billion is nearly four times larger than NASA’s requested funding.

Reconciliation Mechanics and Golden Dome Programs
Funding for missile defense architecture under the Golden Dome initiative relies almost entirely on congressional reconciliation rather than base defense appropriations. The administration positioned the program as an integrated multi-layered missile shield, but its budget footing remains separate from regular military service accounts.
The One Big Beautiful Bill Act of July 2025 initiated the program’s dedicated funding stream. Sourced estimates of total Golden Dome funding inside that statute remain contested across defense publications. Defense One reported $23 billion, the Aerospace Corporation documented $24.4 billion, and SpaceNews cited approximately $25 billion.
Within that initial reconciliation allocation, the Aerospace Corporation itemized $5.6 billion for space-based interceptors and $9.2 billion for space-based tracking and sensor satellites. Air & Space Forces Magazine reported a matching $5.6 billion for space-based interceptors alongside $7.2 billion for sensor networks and $2.0 billion for airborne targeting systems.
For fiscal year 2027, the administration requested $17.5 billion Pentagon-wide to continue development of the Golden Dome architecture. That request split into $14.22 billion for research and development, $2.15 billion for procurement, and $1.15 billion for operation and maintenance. Less than $400 million of that $17.5 billion request sits inside the standard Department of Defense base budget. The remaining 97 percent depends on congressional passage of the proposed fiscal year 2027 reconciliation bill.
The cost projections and timeline for Golden Dome remain subject to debate between administration officials and independent analysts. President Trump stated that Golden Dome would cost approximately $175 billion and achieve initial deployment in about three years. In its fiscal year 2026 budget brief, the Aerospace Corporation noted that independent estimates for orbital space-based interceptor constellations alone range from $161 billion to $542 billion.
The decision to fund missile defense through reconciliation packages creates structural vulnerabilities for long-term satellite constellations. Todd Harrison of the American Enterprise Institute noted that the program sits on unstable footing because reconciliation is unlikely to continue beyond fiscal year 2027, leaving open the question of where program funding will come from in fiscal year 2028 if lines are not transitioned into the base budget.
If Congress declines to pass the fiscal year 2027 reconciliation package and does not move Golden Dome line items into regular appropriations, about 97 percent of the $17.5 billion fiscal year 2027 Golden Dome request would have no funding source. That is the gap Harrison describes. To evaluate how acquisition accounts translate into operational hardware, consult our guide to Space Systems Command structure and programs.
