Oceaneering Freedom AUV Gets a Look for Defense Applications

Oceaneering International said its Aerospace and Defense Technologies (ADTech) business segment won a contract by the Defense Innovation Unit (DIU), a U.S. Department of Defense organization, for the development and testing of the Freedom Autonomous Underwater Vehicle (AUV) as a potential Large Displacement Unmanned Undersea Vehicle (LDUUV) prototype for the U.S. Navy’s Program Office for Advanced Undersea Systems.The contract includes a Manufacturing Readiness Review to assess current production capacity and tradeoffs that could be performed to speed LDUUV capabilities to the fleet.The

RTsys Takes Delivery of More Teledyne DVLs

and drones specialist RTsys announced continued collaboration with Teledyne Marine with further orders for RDI DVLs as demand continues to grow for its range of specialist AUVs comprising of the SEMA ASW training target, COMET-300, NemoSens AUV and µAUV for scientific, industrial and defense applications.RTsys said it took delivery of 20 Pathfinder DVLs and 10 Wayfinder DVLs“When it comes to performance, navigational accuracy is no place to compromise,” said Pierre-Alexandre Caux of RTsys. “Compact and accurate, the RDI DVLs therefore present the perfect fit for our range

Kraken inks $2.7m in Sonar, Subsea Battery Contracts

Kraken Robotics Inc. (TSX-V: PNG, OTCQB: KRKNF) received contracts totalling $2.7m for subsea batteries and synthetic aperture sonar systems (SAS). The SAS sensor contracts represent two new customers, continuing the growth of Kraken's list of users. One customer is a European Research Institute operating next-generation AUVs, and the other is a NATO member country in underwater defense applications. Deliveries will occur in 2024.

Greensea Demonstrates Untethered ROV Operation at Sea

at sea, Greensea said it was able to demonstrate that a VideoRay Defender outfitted with OPENSEA Edge was able to search, classify, map, and inspect during a mock EOD mission while being untethered. Operators supervised the autonomous ROV through Greensea’s EOD Workspace user interface for defense applications, the company said.©GreenseaOver-the-horizon CommsGreensea also utilized its safe C2 (standoff command and control) technology to provide seafloor to over-the-horizon communications. This enabled the supervision of the ROV over very low bandwidth and very high latency-sparse data connections

Hearing the Light: DAS could Revolutionize Subsea Defense

to move forward with the development of the Poseidon nuclear-armed, nuclear-powered AUV, DAS could play an important role in an integrated underwater distant early warning and defense system, providing ISR or relaying targeting data to interceptor vehicles.While DAS shows great promise for defense applications, it does have limitations – at least for now. Its effective range, for example, is roughly 50 to 100 kilometers due to the attenuation of the reflected light during its two-way travel, so a truly large scale DAS array would require some kind of amplification.

meters), capable of accommodating a range of sophisticated sensors, and can remain in situ for weeks, months, or even years, enabling persistent observation and collection of a wide range of hydrographic data.These capabilities, as well as their inherent stealthiness, also make them ideal for defense applications. The United States Navy, for example, currently operates a fleet of Slocum gliders - Littoral Battlespace Sensing Gliders (LBS-Gs) - which are used for anti-submarine warfare (ASW) and intelligence preparation of the operational environment (IPOE).Like their scientific counterparts, LBS-Gs

because they fill a void in autonomous ocean systems as they can work in the surf zone and carry larger sensor payloads on the seafloor. Bayonet has the resources to scale and advance the product line, and strategically, the crawler product line complements Greensea’s autonomy portfolio for defense applications.”Deployable from land or water independent of weather, the range of Bayonet crawlers have been designed to transit along the ocean floor as well as on land, making them the only robotic platform in the world capable of working between 40fsw and the dunes on the beach as well as in the
