Sidus Space (NASDAQ: SIDU) (“Sidus” or the “Company”), an innovative space and defense technology company, today announced the successful completion of the design phase for its FeatherEdge™ 248Vi edge computer, a modular Artificial Intelligence (AI) and Machine Learning (ML) processor line that represents the next evolution in Sidus’ Orlaith™ AI Ecosystem and is purpose-built to support spaceborne, aerial, and autonomous missions. Building on the proven on-orbit performance of FeatherEdge™ 100i, one of the first commercially operational space edge computers, the new 248Vi is engineered to deliver unmatched compute power and ruggedized reliability for mission-critical operations across all domains.

FeatherEdge™ 248Vi Key Features:

• 248 TOPS of AI Performance powered by NVIDIA® Jetson AGX Orin™ Industrial, enabling advanced multi-sensor perception, situational awareness, and near real-time decision-making
• 64 GB LPDDR5 ECC RAM and 680 GB pSLC NVMe SSD for high-speed data processing and storage
• SOSA®/ MOSA®- aligned 3U VPX design for seamless integration into defense and aerospace systems
• Expanded I/O including 10GbE, PCIe® Gen4, SpaceWire, and CANbus for flexible connectivity
• Ruggedized for Extreme Environments with conduction cooling, MIL-STD-810H compliance, and operational range from -40°C to +85°C.
• Radiation-tolerant architecture supporting LEO and GEO missions with up to 100 krad TID.

Compared to previous generations, FeatherEdge™ 248Vi delivers a 2.5x increase in AI compute capability and 4x memory capacity, while maintaining optimized Size, Weight, Power, and Cost (SWaP-C) for unmanned platforms, electronic warfare, and space and defense operations.

“Completing the design of FeatherEdge™ 248Vi marks a major milestone in our mission to redefine edge computing for space and defense,” said Jim Larson, Senior Vice President, AI Strategic Initiatives at Sidus Space. “This cutting-edge high-performance computer sets the stage for advanced AI/ML applications in the most demanding environments and size constrained applications.”

FeatherEdge™ 248Vi is expected to be available for delivery in early Q2 2026. The 248Vi is available in standalone format or as a part of the Fortis™ Maxima suite, which includes Sidus Single Board Computer (SSBC), Position, Navigation, and Timing (PNT), Global Positioning System (GPS) Receiver, Custom Input/Output (I/O) Card, Power Converter Card, and Software Defined Radio (SDR), delivering a comprehensive solution for advanced space and defense missions.

FeatherEdge™ 100i is commercially available for purchase. To reserve your FeatherEdge™ 248Vi, contact sales@sidusspace.com or visit www.sidusspace.com to place a pre-order.
