The two-week wargame, held at the LeMay Center’s Wargame Institute and hosted by Space Delta 10, involved more than 350 participants from defence, industry and academia. Alongside the United States, this year’s participants included Australia, Canada, France, Germany, Italy, Japan, New Zealand, Norway and the United Kingdom. Italy and Norway joined for the first time as observers.
Royal Australian Air Force Wing Commander Adam Carroll, Commanding Officer of the 1st Space Surveillance Unit and Australia’s senior national representative, said the exercise underscored just how critical space services are to the nation’s way of life.
“Access to space services is essential to the Australian way of life, the consequences from the loss of those services is a lesson we continue to embed across our integrated force,” WGCDR Carroll said.
“It has never been more important for like-minded nations to work together to outpace potential threats and provide our senior leaders a clear picture of how space conflict could unfold and what is necessary to deter it.”
Australia’s participation builds on its long-standing role as a trusted partner in global space operations, from tracking deep-space missions through the Canberra Deep Space Communication Complex to operating cutting-edge space surveillance systems in support of collective security.
The 2025 wargame also tested five “notional technologies” – hypothetical future capabilities designed to highlight operational challenges, decision-making gaps and opportunities for greater interoperability. While specific details remain classified, officials said the lessons will help shape the next generation of space capabilities for both governments and industry.
US Space Force Colonel Shannon DaSilva, commander of Space Delta 10, said the wargame has been central to building trust and resilience among allies.
“For more than 25 years, Schriever Wargame has been the place where partner nations come together to test strategies before they’re needed in the real world,” Col DaSilva said. “We’ve built not only scenarios, but relationships – and those are the foundation of our ability to deter, defend and succeed in space.”
Planning is already underway for Schriever Wargame 2027, where participating nations – including Australia – are expected to jointly set objectives for the first time, marking a new phase of international collaboration in space security.
