Space Force training for on-orbit warfare in inaugural Resolute Space exercise

The Space Force has officially kicked off its largest exercise to date known as Resolute Space 2025, a weeks-long event that will pit guardians against realistic simulated threats, according to service officials.

Over 700 Space Force personnel stationed at multiple military bases are participating in the exercise, where guardians will test and train on space-based capabilities to conduct orbital warfare, electromagnetic warfare, cyber warfare and more. During the event, the service will present threat-informed scenarios simulating a fight with an adversary and allowing for troops to use operational military satellites — as well as commercial assets — to counter them.

“As the scenario increases in challenges and complexity, this gives our blue forces a thinking adversary to spar against,” Lt. Col. Shawn Green, commander of the Space Force’s 527th Space Aggressor Squadron, said Tuesday during a briefing with reporters. “Our goal is to create a relevant, realistic, informed threat replication for blue to fight through so that we can increase the probability of success in war.”

Resolute Space 2025 is part of the Department of the Air Force’s massive exercise known as Resolute Force Pacific (REFORPAC), intended to demonstrate the ability of both the Air and Space Forces to rapidly deploy against adversaries in the Indo-Pacific. It is a central piece of the DAF’s new Department Level Exercise (DLE) series that includes other major Air Force training events, such as Mobility Guardian and Bamboo Eagle, happening concurrently.

The Space Force’s exercise began July 8, and will feature guardians stationed at Joint Base Pearl Harbor-Hickam in Hawaii, as well as Peterson, Buckley and Shriever Space Force Bases, according to the service. Other personnel stationed throughout the Indo-Pacific will also participate in Resolute Space 2025, which is slated to wrap up in early August.

To simulate enemy capabilities and attacks, Green said the Space Force created a mission planning cell that will synchronize fires across space-based orbital, cyber and electromagnetic warfare — presenting various moves and countermoves that guardians will have to fight through.

Resolute Space 2025 will also integrate with elements of the REFORPAC exercise, which aims to ensure the Space Force can effectively fight alongside the Air Force in the future.

“We are working to fuse our different mission areas with the time-phased scheme of maneuver as part of the larger scenario,” Green said. “We’re doing that by providing space electromagnetic warfare, orbital warfare [and] cyber warfare. And we’re using those types of activities to fuse into this large, globally integrated exercise for live, virtual, synthetic scenarios so that our training is realistic, relevant and challenging.”

Col. Jay Steingold, Resolute Space director, told reporters that the exercise also spans across other key mission areas — including space domain awareness; satellite communication; positioning, navigation and timing (PNT); intelligence, surveillance and reconnaissance (ISR); missile warning; command and control; and military-commercial integration.

Personnel will be able to use on-orbit space assets designed for training guardians, as well as satellites owned by commercial partners during the exercise, Steingold added.

“We have satellites that we are able to utilize to provide training for our U.S. Space Force guardians, whether that be an understanding of how they quote-unquote fly, or in terms of payload capacities and capabilities and general training on orbit,” he said. “We’re certainly leveraging our commercial partners and their capabilities — not only from their developmental standpoint, but also what they bring to bear in terms of cost savings.”

While the Space Force has held exercises in the past, those events were largely focused on individual mission areas and not at the scale of Resolute Space. Steingold said that while large-scale exercises are costly and time-consuming to plan and execute, participating in Resolute Space 2025 is imperative to improving the service’s capabilities, training and overall integration with the joint force and international allies.

“This is the opportunity to really dig in and find out if we have any weaknesses whatsoever, so we can fill them,” he said. “Whether it’s capabilities that our [Operational Test and Training Infrastructure] partners can bring from a training environments perspective, to actual warfighting capabilities that we need to take us further into the future to ensure the safety and security of the space domain.”
