LRAUV

LRAUV is a long-range autonomous underwater vehicle for persistent oceanographic and marine monitoring missions without continuous ship support. Its propeller-driven design combines powered manoeuvring with low-power transit and drift modes. Operators can launch from shore, plan missions through a web interface and communicate using Wi-Fi, cellular, satellite or acoustic links when each channel is available.

The 12-inch-diameter vehicle weighs about 110 kg and operates from zero to 2.5 knots. Saab specifies more than 1,000 km of range at one knot with a lithium battery, with a lithium-primary configuration extending beyond 2,000 km at 1.5 knots. Standard operating depth is 300 metres, with a 1,500-metre option, and modular payload capacity supports mission-specific ocean sensors.
