Sidus Space Launches Fortis™ VPX: A Ruggedized, AI-Powered 3U OpenVPX Module Supporting Complex Missions from Sea to Space

Modular computing system unlocks new market opportunities across space, defense, and maritime sectors

Sidus Space (NASDAQ: SIDU), (the “Company” or “Sidus”), an innovative space and defense technology provider, today announced the launch of Fortis™ VPX, a ruggedized, modular, SOSA™ aligned computing system engineered for high-reliability command and data handling (C&DH), advanced artificial intelligence/machine learning (AI/ML) processing, and precision navigation in extreme environments. The Fortis™ line of products establishes a new cornerstone in Sidus’ expanding portfolio of space-qualified and defense-grade technologies, designed to support the increasing demand for edge computing across commercial and government sectors.

Fortis™ VPX provides the scalable digital backbone needed to accelerate mission development timelines, reduce integration complexity, and support software-defined operations. Leveraging an open architecture and industry-standard 3U VPX form factor, Fortis™ is built for rapid integration into a range of applications across maritime, land, space, and airborne domains.

“Fortis™ VPX is a force multiplier for AI-driven mission systems,” said Carol Craig, CEO of Sidus Space. “Its modularity, computing power, and SOSA™ aligned compatibility enables customers to quickly adapt to evolving mission requirements while reducing total lifecycle costs.”

Strategic Alignment & Market Relevance

With integrated AI/ML processing, secure navigation, and robust C&DH capabilities, Fortis™ VPX is positioned at the intersection of defense modernization, commercial space infrastructure, and autonomous systems development. The systems’ modularity and dual-use applicability support a broad spectrum of use cases across satellite constellations, tactical ground systems, unmanned aerial vehicles (UAV), and intelligence, surveillance, and reconnaissance (ISR) platforms.

Alignment with the SOSA™ Technical Standard and Sidus’ proprietary IP supports recurring revenue opportunities through both system sales and service-based contracts across defense, aerospace, maritime, and commercial end uses.
