Space Force budget would more than double in Trump’s $1.5 trillion defense plan

WASHINGTON —  The Trump administration’s fiscal year 2027 budget proposal calls for a sharp expansion of U.S. military spending, including a particularly large increase for the U.S. Space Force as the Pentagon shifts resources toward on-orbit capabilities for missile defense.

The White House on April 3 outlined a $1.5 trillion national defense budget, a roughly 42% increase that would mark the largest military topline in U.S. history. The proposal frames the increase as a push to rebuild industrial capacity and accelerate new programs, including a missile defense architecture known as Golden Dome for America.

Within that total, funding for the U.S. Space Force would climb to more than $71 billion, up about $40 billion from fiscal 2026 levels, according to budget materials. The increase represents the most significant infusion of resources since its creation in 2019.

The plan relies in part on an unconventional funding approach. Of the $1.5 trillion defense total, about $1.15 trillion would flow through the standard congressional appropriations process, while roughly $350 billion would be sought through budget reconciliation. 

Reconciliation allows the majority party to advance spending measures with a simple Senate majority, bypassing the 60-vote threshold and bipartisan negotiations that typically govern the annual appropriations process.

That approach allows the administration to propose higher spending levels than would likely pass under normal budget caps, but it also introduces uncertainty. Analysts have questioned whether the administration can successfully use reconciliation to fund defense increases at this scale.

Huge increase for missile defense

In the Space Force request, about $12 billion of its proposed funding would come through reconciliation, most of that in the procurement and research accounts that traditionally sit in the discretionary budget.

A significant portion of the increase is tied to missile defense systems based in orbit. The budget includes about $17 billion for the Golden Dome program, though only a small fraction, roughly $400 million, would be funded through regular appropriations, with the remainder expected to come through reconciliation.

Golden Dome is envisioned as a layered missile defense architecture that would rely in part on satellites to detect, track and potentially enable interception of advanced threats, including hypersonic weapons. While elements of space-based missile warning already exist, the proposal points to a more expansive network of sensors and supporting infrastructure.

A large share of the Space Force’s proposed increase is directed toward missile defense satellite programs. An analysis by aerospace consulting firm Velos shows research, development, test and evaluation shows funding for low Earth orbit missile-tracking satellites rising by nearly $2 billion, alongside a roughly $700 million increase for similar systems in medium Earth orbit. Programs aimed at deploying space-based sensors capable of tracking moving targets would receive an additional $2 billion, including about $800 million routed through mandatory funding.

The request also introduces several new program lines, including a $1.5 billion Space Data Network, automated satellite command-and-control systems, and expanded procurement for proliferated communications satellites—all aimed at improving resilience and data flow across military space architectures.

Taken together, the Space Force budget would allocate $40.6 billion to research and development, $19 billion to procurement, $9.6 billion to operations and maintenance, and $1.8 billion to personnel.

Saltzman: programs will ‘scale’

Gen. Chance Saltzman, the Space Force’s chief of space operations, signaled ahead of the budget release that additional resources were likely, citing growing alignment within the Pentagon and the White House on the need to expand space capabilities.

The scale of the increase reflects a broader shift in Pentagon planning, which increasingly treats space as a central domain of military competition rather than a supporting function.

“Our team has done a really good job of explaining why Space Force capabilities are so critical,” Saltzman said at an April 1 event. “The leadership … agree with our advocacy that space capabilities need to grow.”

He indicated the service intends to scale existing programs rather than launch entirely new ones, accelerating deployment timelines that had previously stretched across much of the decade.

“You can’t wait five, six, seven years to be where we need to be,” Saltzman said. “We need to be there in two years, three years.”

Even so, the proposal faces significant hurdles in Congress, where lawmakers will ultimately determine both the topline and the viability of using reconciliation to fund defense programs at this scale.
