Stratospheric Defense & Strike Node (SADN)

A Next-Generation Platform for Persistent Surveillance, Resilient Deterrence, and Autonomous Response

The SADN is a high-altitude, hydrogen-powered aircraft system designed for long-duration operation in the stratosphere. Powered by solar energy and supercapacitor-supported hydrogen fuel cells, it delivers near-continuous flight time with zero-emission endurance.

Each node supports modular payloads for intelligence, surveillance, and reconnaissance (ISR), electronic warfare (EW), and command-and-control (C2) functions. SADN systems are fully modular and AI-managed, allowing for persistent regional coverage, adaptive response, and autonomous mission execution.

Key applications include:

• Strategic air and missile defense
• ISR coverage in denied or disaster-struck regions
• Electronic warfare and communications relay
• Humanitarian response coordination in remote or contested areas

The SADN platform integrates only commercially available components (COTS), ensuring rapid deployment, affordability, and compliance with existing manufacturing ecosystems. It is a cornerstone technology in our broader Autonomous Deterrence Doctrine (GRAD), aimed at replacing outdated mutual-assured destruction frameworks with precision, autonomy, and resilience.
