The SG-1 Fathom underwater glider developed by Helsing is a compact autonomous drone designed for persistent undersea surveillance. Measuring roughly 1.95 meters in length with a slender 28 cm diameter, this mini-submarine relies on a buoyancy-driven glider design rather than propellers, enabling extremely long endurance.

In fact, each SG-1 Fathom can patrol the ocean depths for up to three months at a time, quietly sweeping for submarines or other underwater threats. Its onboard artificial intelligence system, dubbed Lura , is an advanced software platform built around a large acoustic model (akin to a large language model, but for sound) trained on decades of sonar data.
