Space Defense & Security Summit

Building on the success of its second edition, we are delighted to announce that SDSS will return for a third edition to take place on September 15-16, 2026, at the sophisticated Les Salons Hoche.

The second edition of SDSS exceeded all expectations, marking an extraordinary success with over 480 attendees from 33 countries. ​With 92 expert speakers and 54 partners and sponsors, SDSS fostered critical discussions on space defense, security, and international cooperation. This strong participation solidifies SDSS as a premier platform for global leaders shaping the future of space and defense.​

SDSS will be held just a short five-minute walk from the World Space Business Week’s venue – the Hôtel du Collectionneur. The proximity of the two venues will allow seamless integrations between participants of both events, fostering unparalleled synergies across the space community.
