Envoy AUV

Size & Weight

Envoy is a compact and lightweight vehicle, measuring 8.5 meters in length and 1 meter in diameter, with a displacement of 3,700 kg. Smaller configurations are available to suit specific mission requirements, making it adaptable to various operational scenarios.

Power & Endurance

Envoy offers endurance and range, powered by a 1200 W hydrogen fuel cell. This configuration enables a 2,000 km submerged range and a 15-day endurance. Battery-powered configurations are also available. Additionally, the endurance can be extended through the use of a suction anchor.

Payload & Depth

Envoy’s 500-liter flooded payload bay provides ample space for various sensors and instruments. With a 2,000-meter operating depth, Envoy can explore and survey a wide range of underwater environments, including deep-sea trenches and hydrothermal vents.

Envoy AUV Surveillance

The Envoy AUV, previously known as the Solus-LR is a long-endurance underwater vehicle powered by a fuel cell. It can remain submerged for months, traveling thousands of kilometers. Using a suction anchor, it secures itself to the seabed for covert, long-duration missions in challenging underwater environments. This enables persistent surveillance and data collection, making the Envoy AUV valuable for a wide range of underwater applications, from scientific research to national security.
