NSSA’s International Security Space Forum 2026 will take place October 20–21, convening senior government, military, and industry leaders from the United States and allied nations engaged in national security space cooperation.

At a time of growing geopolitical instability and increasingly contested space operations, the need for trusted international partnerships has never been more urgent. Allied nations depend upon resilient space capabilities to enable communications, missile warning, positioning, navigation and timing, weather monitoring, intelligence collection, and integrated military operations across every domain. As strategic competitors continue to expand their space capabilities, strengthening cooperation among like-minded nations is essential to ensuring collective security, operational interoperability, and long-term stability.

The Forum will bring together distinguished representatives from Australia, Canada, France, Germany, Italy, Japan, Norway, the United Kingdom, the United States, and other partner nations to engage in strategic dialogue on the future of security cooperation in space. Through keynote addresses, executive discussions, and thematic panels, participants will examine the evolving threat environment, emerging operational challenges, and opportunities to deepen allied collaboration across space operations, acquisition, industrial partnerships, and policy development.

Discussions throughout the Forum will focus on advancing practical cooperation among allies and partners, including improving operational integration, strengthening information sharing, enhancing resilience of critical space architectures, aligning acquisition approaches, and identifying policy frameworks that enable more effective multinational collaboration. Sessions will also explore how governments and industry can work together to accelerate innovation, improve interoperability, and support the development of shared capabilities in support of collective defense objectives.

The International Security Space Forum 2026 is intended not only as a venue for strategic discussion, but as a catalyst for enduring partnerships and actionable outcomes. The Forum seeks to strengthen relationships among allied governments and industry leaders, foster greater alignment on operational and acquisition priorities, and advance collaborative approaches that reinforce security, deterrence, and stability in the space domain.

Seating is limited, and early registration is strongly encouraged. Join the international security space community this October for two days of high-level engagement, partnership-building, and forward-looking dialogue at the intersection of space, security, and allied cooperation.
