WISeKey International Holding Ltd, through its space technology subsidiary WISeSat.Space, and semiconductors, PKI, and post-quantum technology subsidiary SEALSQ Corp, announced the completion of a pilot phase in their strategic partnership with the Space Command of the Swiss Armed Forces. The collaboration, initiated in 2022 and further strengthened in 2024, has focused on evaluating technical and operational building blocks relevant to a future Swiss sovereign and quantum-resilient space communications infrastructure. During this pilot phase, WISeSat, SEALSQ and their partners conducted satellite missions, payload integration work and secure communications testing designed to assess architecture options, operational concepts and future government and defense use cases.

The program has provided technical validation and practical lessons for the next stage of development. Building on these results, WISeSat and the Swiss Space Command continue their partnership. WISeSat is now preparing a next-generation 6U mission, planned to launch in the Fourth Quarter 2026.

The new platform is intended to offer greater payload flexibility, longer mission endurance and broader application potential for secure communications and other sovereign space infrastructure uses. The first 15 next-generation 6U satellites planned by 2027 are intended to form the initial elements of WISeSat?s Quantum Space Orbital Cloud. WISeSat is expected to own and operate these satellites and the associated space and ground segment in cooperation with the Swiss Space Command as part of its program architecture, while SEALSQ is expected to contribute its quantum and cybersecurity technology stack across selected constellation resources and capabilities.

The new 6U generation is also intended to serve as a modular in-orbit platform that will allow Swiss space companies to test and validate selected products, subsystems and applications in a real mission environment, and therefore contribute to the Swiss innovation ecosystem. WISeSat?s objective is to provide a practical framework through which emerging Swiss New Space players may gain access to flight heritage, accelerate development cycles and demonstrate technologies relevant to sovereign and secure space infrastructure. The 6U mission and the first 15 satellites planned by 2027 are intended to constitute the first building blocks of WISeSat?s QSOC roadmap, with full operational capability currently envisioned for 2033.

As the programme develops, future platform generations could support a broader set of payloads and services, depending on technical validation, mission priorities, financing and customer demand. These may include secure communications payloads, advanced post-quantum cryptographic functions, sovereign identity and trust infrastructure, direct-to-device connectivity, optical communications, selected sensing capabilities, onboard processing, secure data storage and other digital infrastructure services. This roadmap reflects WISeSat?s ambition to help establish a Swiss-led, secure and scalable orbital infrastructure serving both sovereign and commercial applications.
