The U.S. Space Force is pressing forward with a plan to absorb nearly 600 Air National Guard members into its ranks, a move intended to bolster the still-young military branch.

However, the proposal has sparked strong opposition from several state governors who argue that the transfer infringes on their authority and could deprive states of highly skilled personnel.

At the center of the debate are 578 part-time service members currently assigned to space-related missions within the Air National Guard.

These positions are spread across six states—Alaska, California, Colorado, Florida, Hawaii, and Ohio—as well as the Air National Guard headquarters.

Under the 2025 National Defense Authorization Act, these roles are slated to move under the jurisdiction of the U.S. Space Force.

The Space Force, established in 2019 during former President Donald Trump’s first term, has been steadily taking over space missions that were previously managed by the Air Force.

Yet, this latest phase of consolidation—bringing in the Guard members—has proven politically and administratively thorny.

“We are actively pursuing where do we want our part-time workforce? What type of work do they do?” Gen. Chance Saltzman, Chief of Space Operations, said during a Politico event in Washington last week.

Saltzman emphasized the value of maintaining a part-time component in the Space Force, especially as the service refines its personnel structure.

Despite the seemingly small number of affected troops, the move has triggered alarm among governors and lawmakers who see it as a federal overreach.

The National Governors Association issued a strongly worded statement in April, urging the Department of War to halt the transfers.

“We urge that any transfers cease immediately and that there be direct and open engagement with governors,” the association stated.

The concern goes beyond constitutional questions of state versus federal control. Governors are also worried about the economic and professional impacts on their states.

Space-related positions are among the most lucrative in both the military and the private sector.

Governors argue that relocating those billets to the Space Force risks stripping states of a highly valuable part-time workforce.

If Guard members are required to move to remain in their specialized roles, states stand to lose critical talent.

Senator Markwayne Mullin, a Republican from Oklahoma, echoed those concerns during a Senate hearing on Air Force manpower.

“There’s a lot of concern in the National Guard about these individuals who are highly skilled that want to be in the Guard being transferred out,” he said.

For now, the tension between the Space Force and state governments has prevented the service from directly approaching Guard members to discuss transferring.

Under current law, each service member will have a choice: remain with their state Guard unit and retrain into another specialty, or transfer to the Space Force as a part-time member.

Crucially, even for those who transfer, their current positions would remain in the same geographic locations for at least the next 10 years.

This provision, included in the 2025 defense bill, is an attempt to mitigate concerns about mass relocations and the erosion of state-based expertise.

The breakdown of affected personnel includes:

Alaska: 33
California: 126
Colorado: 119
Florida: 75
Hawaii: 130
Ohio: 69
Air National Guard Headquarters: 26

The proposal to create a separate Space Force National Guard had previously been floated but ultimately dismissed as impractical due to the small size such a force would entail.

Instead, the current plan aims to maintain the part-time nature of these roles while shifting oversight to the Space Force.

Still, state officials and National Guard advocates are not entirely convinced.

They remain wary that what starts as a relatively small transfer could lay the groundwork for broader federal control over state Guard resources.

As the Space Force continues to evolve, balancing its growing operational needs with the traditional structure of the National Guard will remain a delicate and politically charged challenge.

The coming months may see further negotiations between Pentagon officials and governors as both sides grapple with how to best integrate cutting-edge space missions into the national defense framework—without alienating the states that have long played a vital role in supporting them.
