Getting to the Bottom of the Navies' Mine Warfare Challenges

The General Dynamics Mission Systems Bluefin Robotics Knifefish UUV detects, classifies and identifies volume, proud and buried mines in high-clutter underwater environments, and is a critical element of the LCS Mine Countermeasure (MCM) mission package. Knifefish’s job is to detect, avoid and identify mine threats, reducing the risk to personnel by operating in the minefield as an off-board sensor while the host ship stays outside the minefield boundaries. Knifefish also gathers environmental d

To find the mine warfare challenge with the highest degree of difficulty, start at the bottom.Lurking unseen below the surface, naval mines pose a serious problem. They’re cheap, relatively easy to deploy and can inflict heavy damage against even the most sophisticated warships. They can be hard to detect and difficult to counter. What you can’t see can hurt you. And the most difficult mines to find and eliminate are bottom and buried mines. Navies have developed ships to hunt for mines in the water column so they can be avoided or destroyed…

Knifefish is a medium-class mine countermeasure UUV designed for deployment off the Littoral Combat Ship. OPTEVFOR is the Navy’s sole test and evaluation organization for surface, air, and un

The U.S. Navy uses unmanned and robotic underwater vehicles for a multitude of functions, including environmental sensing, mine hunting, and salvage. The Navy plans to evolve an unmanned systems operating concept that is platform agnostic and capable of operating in highly complex contested environments with minimal operator interaction.The most recent edition of the Navy’s Unmanned Systems (UxS) Roadmap was issued in 2018, and a new version is expected in the near future. The 2018 document states that UxS will operate in every domain…

The ocean is a very large and increasingly congested place. More and more shipping and industry is using it. But the risks hidden below the waterline, that established navigational tools don’t always detect, remain.But what if the trend for new surface-based sensor technology, the likes of which enable cars to detect potential collision hazards, could be available for shipping to detect underwater obstacles?That’s just what Sonardyne International Ltd. has developed with its new Vigilant forward looking sonar (FLS).

At CMRE, it’s not just about the science. It’s about building trust and confidence in resilient systems. An interview with Dr. Catherine Warner, Director, NATO Center for Maritime Research and Experimentation, La Spezia, ItalyTell us a little about yourself and CMRE. What does CMRE do, and how do you see your mission evolving?I came here from the Pentagon, where I was the science advisor for the director of operational test and evaluation. My experience has been working with operators on systems that they’re getting ready to field.

Lockheed Martin $24M Anti Sub Systems Contract

Advanced acoustic processing and tracking capabilities provided by Lockheed Martin (NYSE: LMT) will enhance underwater surveillance and help increase situational awareness for the U.S. Navy fleet. Lockheed Martin has been awarded a follow-on contract from the Navy's Space and Naval Warfare Systems Command to provide technology updates and new concepts to detect and track submarines. This contract extension is valued at $24m. The team will engineer enhancements to the Navy's common Integrated Undersea Sensor System hardware and software baseline, or Integrated Common Processor (ICP) system, which assists operators in localizing and tracking surface and subsurface maritime contacts.

Wesmar’s Sonar Series EV850

WESMAR is introducing the EV850 series, a new, all digital navigation and security sonar. This searchlight sonar provides detailed information about the waters around and beneath boats while at anchor or cruising. Thanks to active stabilization, the new sonar series provides target tracking even in rough water. Additionally, the sonar screen never leaves the monitor when making adjustments, essential to avoiding hazards or tracking divers. The sonar has the ability to detect and follow divers many hundreds of feet away, providing early warning and time for response.
