SG-1 Fathom British Autonomous Underwater Vehicle (AUV)

The SG-1 Fathom British Autonomous Underwater Vehicle (AUV) is an autonomous, propellerless vehicle capable of gliding silently beneath the sea at speeds of 1 to 2 knots for up to three months. They are designed for discreet deployment and long-endurance missions. As an underwater satellite constellation, these gliders significantly reduce detection latency and operational workload while enhancing maritime situational awareness. The SG-1 focuses on persistent ISR (intelligence, surveillance, and reconnaissance), offering complementary functions in alliance operations.
