For the demonstration the Sabertooth was equipped with a high-end sensor suite including side scan sonar, sub bottom profilers, high frequency imaging sonar, multibeam echo sounder and cameras, along with GPS, DVL and inertial measurement unit (IMU) supporting the navigation. Processing of the trajectory data was achieved with an algorithm developed by Saab Dynamics.

Lockheed Martin previously made upgrades to the RMMV to enable the unmanned vessel to perform coastal defense, or intelligence, surveillance, reconnaissance (ISR).

View Full StoryWhat the admiral is hinting at is using submarines to launch unmanned systems. These could be as simple as a communications buoy that rises to the surface, waits a set time, and transmits. They could be expendable drones, launched from a submarine’s missile tubes the same way as a Tomahawk. They could be complex mini-subs in themselves, known as large diameter underwater unmanned vehicles (LDUUVs), that can launch from a manned sub to conduct a long-range mission. They could even be large payload modules that are towed behind a submarine until, at a strategic point, it releases them to settle to the sea floor and await the signal to unleash their payload of UUVs, drones or missiles.

We’ll be leading the marine technologies theme and developing a new AUV that can go underneath ice cavities, sample the biology and provide feedback for all the other themes.”

Surveys will be performed with a 3000m-rated autonomous underwater vehicle (AUV). The AUV is capable of delivering high resolution high quality HISAS bathymetry and side scan sonar data for Sub Bottom Profiling (SBP) at high speeds.

Since November they have mapped about 40 per cent of the 30,000 square kilometre priority search area. “The autonomous vehicle is searching inside a volcano at the moment,”
