The U.S. Space Force and nine partner nations recently participated in the two-week Schriever Wargame 2025.
The exercise tested strategies, evaluated future technologies and strengthened international cooperation in space.
“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,” U.S. Space Force Col. Shannon DaSilva and Space Delta 10 commander, said. “We’ve built not only scenarios, but relationships — and those are the foundation of our ability to deter, defend and succeed in space.”
The exercise included hypothetical future capabilities used to stress-test decision making and identify gaps in how partners share data and operate together.
Space Delta 10 hosted the event at the LeMay Center’s Wargame Institute. There were more than 350 participants from the U.S. Department of Defense, partner nations, industry and academia. Participants included representatives from Australia, Canada, France, Germany, Italy, Japan, New Zealand, Norway, the United Kingdom and the United States. Italy and Norway were first-time observers.
“Our partnerships grow stronger each time we come together,” DaSilva said. “Schriever Wargame 2025 proved that the future of space security lies in partnership, trust, and shared vision.”
During Schriever Wargame 2027 it is expected that participating nations will jointly set wargame objectives.
