Innovative underwater technologies have been demonstrated at the largest maritime exposition in the U.S. – the Navy League’s Sea-Air-Space Exposition, National Harbour, Maryland from 9th to 11th April 2018, reported Defense News.

Among the AUVs (autonomous underwater vehicles) featured: a Hydroid’s high-speed, micro-sized vehicle and a Teledyne Energy’s subsea refuelling station.

The small (with length of about 91 cm and diameter of about 12 cm) vehicle Remus M3V of Hydroid may reach speeds of more than 10 knots and depths of up to 300 m. It is intended for ISR (intelligence, surveillance and reconnaissance), search and survey, and multivehicle missions. Its advantages, except the small size, are the low cost and compatibility with existing AUV operating systems.

According to Justin S. Reid, business development manager at Hydroid, “The Navy always wants more with less. They want a smaller vehicle that can do the same things as a larger vehicle, and also the price point to match it.”

The Remus M3V may also operate in buoy mode thanks to its variable centre of gravity.

The Teledyne’s subsea power station is designed for remote refuelling of underwater vehicles. It is deployable via ship or helicopter and its energy storage is 200 kilowatt-hours. The operating depth is 3,000 m.
