    This looks to be the Golden Age of MCM warfare with the emergence of many innovative capabilities, manned and unmanned,

    Navy pursues advanced drone ship mine-hunting tech

    BY KATHERINE OWENSMAR 07, 2017
    The Navy is continuing to move forward with development of the Unmanned Influence Sweep System (UISS) countermine technologies as part of its overall effort to create a fleet of unmanned vehicles capable of enhanced coordination while performing a wider range of technical operations...

    The UISS is made of a minesweeping unit and the Textron Common Unmanned Surface Vehicle (CUSV) that tows it. As Defense Systems previously reported, the UISS locates and detonates sub-sea mines through emitting sounds and magnetic signatures that replicate those of a ship in order to set off mines programmed to detect passing ships... Textron reports that the CUSV is capable of traveling for up to 20 hours with a 4,000-pound load at speeds up to 20 knots per hour... In addition, according to the U.S. Naval Institute, the CUSV is being designed so that it can be easily transitioned between roles as a minesweeper, and a mine hunting and detonating support craft, with the ability to tow side-scan sonar, mine neutralization equipment, intelligence, surveillance and reconnaissance technology (ISR), and nonlethal weapons.

    “Unlike purely remote controlled boats, these [USVs] are able to perceive their environment and plan their routes without human intervention,” Robert Brizzola, program manager, Sea Platforms and Weapons, ONR, said

    The depths these UUVs are intended to descend to are incredible. Stupid question - do these things have pressure hulls?

    all the deep diving ones have to, otherwise they'll get crushed pretty rapidly once they hit the threshold

    Thanks. I was wondering if it was possible to harden key systems against the pressure and doing away with a pressure hull to save some weight and cost. Any cargo intended to operate at those depths would necessarily be similarly hardened.

    all goes back to CONOPs in the end - so mission profiles for the USV

    the majority of USV are running around in depths where crushing will only happen if they lose comms or control and head to the bottom (unless the software hits a failsafe mode and forces return to the top)

    the new generation of combatant USV's will be able to reach the same depths as large subs so as to engage in a form of manouvre parity etc....

    Some other interesting presentations in the video with Underwater vehicle developments from Sea Air Space 2017
    What caught my attention was that Raytheon sell upgrade kits for Mk46 torpedoes to convert them to Mk 54. I wonder if the ADF is buying new torpedoes or kits

    The Mk54 has also had upgrades from the Mk48 CBASS, Bl7 so its a generational improvement

    And are those upgrades from CBASS available to all Mk54 users or are some features protected for use only by the JV partners?

    to be honest, I have NFI

    I only ever looked at the developments from an Oz/US perspective. I kind of assumed that the libraries etc were tied to the region

    I would think that the software also has some common capabilities for the indian ocean

    Thanks, the first time I'd heard of it.

    the USN has been interested in vessel based management of USV, UUV, swarm UROV tech for over a decade

    the problems have revolved around payload, persistence, swarm comms, redundancy/fallback/retrieval, AI issues

    they've come a long way in the last 10 years and I suspect that things are far further ahead than indicated based on what I dealt with many moons ago

    In retrospect and AFAIK that's basically one of the capabilities of a Mk 48 ie. locate a hostile with active sonar and communicate this back via tether to it's mother ship. Though this new UUV doesn't appear to a kamikaze.:cool:
