The Space Force is requesting $71 billion for fiscal 2027 in the White House’s newly released budget proposal, a topline that would bring with it major funding increases for missile warning programs, launch procurement, and end strength.
Space Force leaders in recent months have signaled they expect significant budget growth for the U.S. military’s smallest service in fiscal ’27, arguing that its funding—which currently sits at around $40 billion—needs to increase to meet demand for more space capabilities. The White House released the high-level details of its proposed budget April 3, and it appears to deliver on the service’s expectations.
Speaking April 1, just before the formal release, Chief of Space Operations Gen. Chance Saltzman said the budget growth reflects alignment among stakeholders within the service and the Pentagon that space capabilities are critical to joint force operations.
“We were able to make that case and the leadership in the Department of War, the leadership in [the Office of Management and Budget,] certainly the leadership of the White House and the president agree with us, agree with our advocacy, that space capabilities need to grow, that the Space Force’s capacity needs to grow,” Saltzman said at the Mitchell Institute’s Spacepower Forum.
The Space Force’s request, undergirded by a record $1.5 trillion defense topline, would deliver approximately $31 billion above last year’s budget to support key priorities like missile warning, tracking, and defense; space-based moving target indication; satellite communications; and data transport and command and control.
Of that $71 billion, about $59 billion would be funded through the base, or “discretionary,” request and $12 billion would come through a separate reconciliation package. The research and development account would grow to more than $40 billion—topping the entire service’s request from 2026—and its procurement account would increase to $19 billion, more than five times what it requested last year. The proposal also includes $1.9 billion for Space Force personnel, up from the $1.6 billion it asked for in fiscal ’26, and $9.7 billion for operations and maintenance, a nearly $4 billion increase.
Space Force 2027 Budget
| Category | Fiscal 26 Budget | Fiscal 27 Budget | Increase |
|---|---|---|---|
| Military Personnel | $1.6 billion | $1.9 billion | $300 million |
| O&M | $5.9 billion | $9.7 billion | $3.8 billion |
| RDT&E | $29 billion | $40.6 billion | $11.6 billion |
| Procurement | $3.6 billion | $19 billion | $15.4 billion |
| Totals | $40 billion | $71 billion | $31 billion |
More Systems, Guardians
Saltzman said the Space Force’s budget request reflects its need to grow existing programs and add new ones. That’s largely reflected in the service’s research and development and procurement accounts, which would see the greatest gains from the White House’s proposal, with much of that funding going toward the service’s highest priorities.
That includes the Pentagon’s Golden Dome project, a signature Trump administration effort to bolster U.S. defenses against advanced missile threats. The defense budget requests $17.5 billion for Golden Dome, and while it’s not clear how much of that funding resides within the Space Force’s purview, major increases to the service’s existing space-based missile warning, tracking, and defense portfolio provide at least some indication.
The request includes nearly $5 billion for the Space Force’s Resilient Missile Warning and Tracking program, which is fielding satellites to low-Earth orbit and medium-Earth orbit—a $1.7 billion increase from its fiscal ’26 budget, according to high-level Pentagon budget documents. About $3.5 billion of that is for the LEO program, managed by the Space Development Agency, and $1.4 billion would be funneled toward the MEO layer, which Space Systems Command oversees.
The Space Force’s Long Range Kill Chains program would see an increase of nearly $1 billion for a total request of $1.3 billion, and another $1.5 billion would fund an effort called “Automate Sat C2,” which may support broader Space Force efforts to improve satellite command-and-control capabilities.
Efforts to build out a space-based moving target indication constellation would also see a boost. The Space Force’s R&D budget includes $1 billion for Space-Based MTI and, notably, its procurement request adds $7 billion for Air Moving Targeting satellites and $1 billion for its Ground Moving Target Indicator program.
Three other noteworthy increases in the Space Force’s R&D and procurement budgets: a $1.5 billion add for a new funding line, Proliferated LEO SATCOM; $4 billion for 22 National Security Space Launch missions; and $1.5 billion for the Space Data Network, the service’s larger data transport effort, which will include dedicated military spacecraft as well as commercial satellites and will support Golden Dome.
To manage the Space Force’s growing portfolio of missions and systems, Saltzman and Chief Master Sergeant of the Space Force John Bentivegna have said the service’s current cadre of 10,000 Guardians needs to double in size in the coming years.
With a $330 million increase in personnel funding, the fiscal ’27 budget puts the Space Force on a path toward increasing its end strength, but the doubling officials have called for won’t come for a few years. Funding projections from the White House’s Office of Management and Budget show the service’s personnel budget growing from $1.8 billion in 2027 to $3.2 billion in fiscal 2030.
Execution, Long-Term Stability
While the fiscal 2027 budget is historic for its size and scope, it’s far from a done deal, as Congress must still approve the White House’s proposal. The Trump administration successfully passed a reconciliation bill to supplement last year’s spending, but the politics of the upcoming budget cycle will likely make passage more difficult this time around, particularly as midterm elections loom.
Byron Callan, a defense analyst for Capital Alpha Partners, said as much in a recent newsletter.
“We remain quite skeptical that these figures will be achieved for defense (unless there is another major war) because of the challenge of passing a reconciliation bill and the high probability that the 2026 mid-term election returns split-party control in Congress,” he wrote.
Further, the Trump administration’s decision to rely heavily on the reconciliation process to pay the bill for major programs, raises questions about whether funding growth will be sustained over time and whether the department can execute such a significant influx of cash.
Of the Space Force’s $71 billion request, around $59 billion is built into the Defense Department’s base budget, with the remaining $12 billion funded through reconciliation. OMB’s five-year funding projection, called the Future Years Defense Program, shows the service’s topline dropping to $69 billion in fiscal 2028 and $65 billion by fiscal 2030.
As for execution, Saltzman said the Space Force has done the foundational work to make sure it can “effectively spend those additional resources.”
“We know the systems that are required. We know the kinds of resiliency that’s needed. We know the training capacity that we have to add,” he said at the Mitchell Institute event. “Now, hopefully, with just the new resources, it’s just more money onto existing programs to rapidly expand those capabilities. That’s going to be our strategy.”
