WASHINGTON — Scenarios for future Schriever Wargames will be planned jointly with allies rather than having objectives set unilaterally by the US Space Force, according to a senior service official.
“For the last 25 years, the Schriever Wargame series has been bringing nations together to work towards shared security and interoperability in the space domain. And in the future, with Schriever Wargame 2027, these nations will set the objectives for the war game for the first time jointly as a group,” Col. Shannon DaSilva, Space Delta 10 commander, told reporters Monday.
“We’re trying to make this less, intentionally less, US centric,” she added. “The chief of Space Operations set the objectives for this year’s wargame, and we’re hoping that that’s this is the last time that the US will unilaterally set the objectives. And rolling into Schriever Wargame 2027, our intent is that all the nations will jointly set the objectives for the wargame, and that we will be testing operational concepts that are more internationally focused.”
Space Delta 10 is the wargaming and doctrine-development unit of the US Space Force’s Space Training and Readiness Command (STARCOM), and led this year’s 2025 Schriever Wargame Capstone (SW 25).
Running from Aug. 10-21 at the LeMay Center’s Wargame Institute at Maxwell Air Force Base, Ala., this year’s biennial table-top game involves “more than 350 participants from the United States Department of Defense, industry, and partner nations to explore strategic challenges in a future conflict scenario,” according to a STARCOM press release.
There are a total of nine allied and partner nations participating in SW 25, a STARCOM spokesperson told Breaking Defense: Australia, Canada, France, Germany, Italy, Japan, New Zealand, Norway, and the United Kingdom. Italy and Norway, as first time attendees, sent only observers, the spokesperson said.
However, the STARCOM spokesperson said that release of a full list of countries involved wouldn’t be available until the command had confirmed which governments had approved a release of their participation.
The scenario for SW 25 was centered on conflict in the Indo-Pacific theater a decade in the future, Lt. Col. Justin Jones, who commands Delta 10’s Operations Squadron, told reporters.
“Our scenario is centered in the INDOPACOM [US Indo-Pacific Command] area of responsibility. So we’re focused on how we operate together and develop partnerships in that AOR to meet our space focused competitive endurance objectives,” he said.
One feature of this year’s game is the use of “five advanced notional technology concepts to prompt discussion on future investment and integration,” STARCOM’s press release noted.
Jones explained that those concepts involved “technologies that we feel would be likely in the realm of the possible here in the near future, and they’re focused largely on how we work together as a coalition to share data, to reduce decision-making timelines and to really better share information with one another, so that we have a complete picture of what’s going on in the operational environment.”
Further, DaSilva said, they were chosen with an eye to where nations might want to invest in the future.
“The idea was to explore what might be in the realm of the possible for future investment discussions and integration with our partners,” she said.
While stressing that she couldn’t “go into much detail,” DaSilva added that these include technologies related to “space domain awareness, communication, [and] collaboration tools” that aren’t currently available.
Pressed on why so few details about the five technology concepts could be revealed, she explained that participating nations outside the US were working under different classification rules.
“We have other partners involved that feel like things should be held at different classification levels, and we’re trying to be sensitive to the fact that there isn’t a common, approved security classification guide to the game,” DaSilva said. “And things that the United States feel should be held at potentially a lower or unclassified [level] — things that we might be more comfortable talking about in the open — some of our newer partners are less comfortable [about].”
