Overview
- GABLER and FLANQ completed Sea Acceptance Tests in June 2026 that validated the seaworthiness and core systems of their Ranger torpedo-tube-launched uncrewed surface vessel.
- Ranger is a 4.5‑metre boat built to fit a 21‑inch (533 mm) torpedo tube, rated to survive 300 metres depth during launch and then autonomously surface to carry out intelligence, surveillance, and reconnaissance missions.
- The platform uses a folding keel and sensor mast, an electric drivetrain designed to be quiet, and a configurable payload bay so navies can swap in cameras, electronic sensors, or other mission equipment.
- GABLER will lead commercialization and host-submarine integration while FLANQ supplies autonomy and software, and the partners say they are also developing a one-way attack variant called Strike.
- Because Ranger can launch from existing torpedo tubes, the demonstrator offers a lower-cost way for submarines to gather surface data without surfacing, a capability that could change submarine tactics and force planners to reassess risk to crews.
