Overview
- GABLER and FLANQ completed Sea Acceptance Testing for the Ranger demonstrator in June 2026, validating seaworthiness and core system performance during at-sea trials.
- Ranger is a 4.5‑metre uncrewed surface vessel built to fit a standard 21‑inch (533 mm) submarine torpedo tube and is rated to survive depths of about 300 metres.
- The vehicle uses a folding keel and retractable sensor mast plus a quiet electric drive to deploy from underwater, autonomously surface, and carry mission-configurable sensor payloads for ISR tasks.
- GABLER will lead commercialization and host-platform integration as development moves toward operational capability and the partners are advancing a one-way-attack variant called Strike.
- The programme moved from concept in September 2025 to proof-of-concept in roughly ten months by using commercial components, AI-enabled autonomy, and open architectures to offer navies lower-cost, attritable ways to extend submarine reach.
