Kongsberg Maritime subsidiary Hydroid has been awarded a contract by the Japanese Ministry of Defence (MoD) to supply one REMUS 600 autonomous undersea vehicle (AUV) for performing mine countermeasure operations.

The new order brings the Japanese MoD’s AUV fleet to five vehicles, which include four REMUS 100 systems procured earlier in the year.

Hydroid president and co-founder Christopher von Alt said: "The REMUS 600 is ideally suited for this application, as, when fully configured, its exceptional endurance allows it to operate underwater for long periods of time in varying depths of water."

The REMUS 600 AUVs feature different types of sensors to aid in hydrographic surveys, debris field mapping, environmental monitoring, fishery operations, scientific sampling and mapping, as well as search and salvage operations.

Specifically designed for operations requiring extended endurance, the REMUS 600 AUV also supports mine detection operation, which includes locating explosive devices and other undetonated ordnances, as well as finding and classifying submerged objects.

"The REMUS 600’s endurance allows it to operate underwater for long periods of time in varying depths of water."

The modular REMUS AUV’s, with increased payload capacity and greater operating depth, assist in harbour security operations and many basic and applied research programmes.

Designed with Office of Naval Research funding, the REMUS 600 AUV is slightly buoyant and can operate up to depths of 600m, while enabling increased operational scope.

Capable of configuring for 1,500m or 3,000m operations, the highly versatile REMUS 600 system can remain operational for up to 70 hours, while the increased size and power capacity allow it to carry large payloads to meet mission requirements.

The Japanese MoD currently uses REMUS 100 systems for conducting mine countermeasure operations, as well as investigating and mapping sea floor dispersion of contaminants.

More than 300 Hydroid REMUS AUVs are currently operational around the world.
