Two German firms have demonstrated a drone boat designed to emerge from submarine torpedo tubes, completing sea trials that validate the concept in real maritime conditions.

Two German firms have demonstrated a drone boat designed to emerge from submarine torpedo tubes, completing sea trials that validate the concept in real maritime conditions.

Submarine developer GABLER and Rostock-based FLANQ tested their jointly developed “Ranger” demonstrator, a torpedo-tube-launched uncrewed surface vessel (TTL USV) designed to give naval forces a new way to deploy autonomous systems.

The platform is built to launch from standard 21-inch (53-centimeter) torpedo tubes and operate independently on covert intelligence, surveillance, and reconnaissance (ISR) missions.
