Sovereign, air-gapped AI for defence and security

For defence, AI must work where there is no network, without depending on foreign suppliers and without fuel convoys. An off-grid, air-gapped AI data center brings compute and analysis where it is needed, with own energy and verifiable open-weight models.

THE PROBLEM

Why on-site, why off-grid.

  • Disconnected or degraded environments (DDIL), where connectivity cannot be taken for granted.
  • Classified data that cannot leave the perimeter.
  • Energy dependence of forward bases, with exposed fuel logistics.

THE RULES
  • The Ministry’s “AI and Defence – 2026 Edition” strategy aims at strategic autonomy and sovereign compute, with a Defence AI Office and Laboratory.
  • Law 132/2025 (Art. 6) excludes AI activities for national security from its scope; they follow the Defence security rules.
  • For SAFE funds the European supply chain matters.
WHERE ON-SITE AI HELPS
  • decision support and document analysis
  • logistics and predictive maintenance
  • translation and transcription
  • on-site analysis of sensor and satellite imagery
  • training and simulation

06 / FAQ

Questions people ask.

01What is an air-gapped AI?+

A system completely isolated from the internet: models and updates arrive on verified physical media.

02Can open-source models be used in defence?+

Yes: open weights can be inspected, installed on site and used without depending on an external service. The license must be checked for every installed release.

03How is a data center powered in an area with no grid?+

Photovoltaic and JA Planet storage, with a backup generator when needed.
