The Rise of the Underwater Sentinel: How Uncrewed Systems and Advanced Sonar are Reshaping Maritime Security
A recent multi-million-pound contract awarded to SEA, part of the Cohort plc Group, to supply its KraitArray technology to Liquid Robotics (a Boeing Company) signals a pivotal shift in maritime surveillance. This isn’t just about one deal; it’s a glimpse into a future where uncrewed systems, equipped with sophisticated sensors, are increasingly responsible for safeguarding our oceans. The integration of KraitArray with Liquid Robotics’ Wave Glider USV is accelerating the deployment of persistent, autonomous underwater detection capabilities.
Persistent Surveillance: The New Normal
For decades, naval forces have relied on expensive, crewed vessels for anti-submarine warfare (ASW), intelligence, surveillance, and reconnaissance (ISR), and maritime domain awareness (MDA). However, the increasing complexity of underwater threats – from quiet submarines to autonomous underwater vehicles (AUVs) – demands a more adaptable and cost-effective approach. Uncrewed systems offer precisely that. They can loiter for extended periods, covering vast areas without the logistical burden and risk associated with manned operations.
The KraitArray’s low size, weight, and power (SWaP) characteristics are crucial here. Traditional towed array sonars are bulky and require significant power, limiting their use on smaller platforms. KraitArray’s modular design allows it to be seamlessly integrated into the Wave Glider, creating a highly mobile and discreet surveillance asset. According to a 2023 report by the Center for Strategic and International Studies (CSIS), investment in uncrewed maritime systems is projected to grow by 15% annually over the next decade, driven by this need for persistent surveillance.
Beyond Anti-Submarine Warfare: Expanding Applications
While ASW is a primary driver, the applications of this technology extend far beyond detecting submarines. KraitArray and similar systems are proving invaluable for:
- Illegal Fishing Detection: Identifying and tracking vessels engaged in illegal, unreported, and unregulated (IUU) fishing.
- Pipeline and Cable Protection: Monitoring critical underwater infrastructure for damage or tampering.
- Environmental Monitoring: Collecting data on marine life, pollution levels, and oceanographic conditions.
- Mine Countermeasures: Locating and identifying underwater mines.
The US Navy, for example, is actively exploring the use of USVs equipped with advanced sonar to augment its existing mine countermeasures capabilities. This reduces the risk to personnel and allows for more thorough coverage of potential minefields.
The Innovation Ecosystem: Collaboration is Key
The partnership between SEA and Liquid Robotics highlights a crucial trend: collaboration. Developing and deploying these complex systems requires expertise in multiple domains – sonar technology, uncrewed vehicle design, data analytics, and communications. Companies are increasingly forming strategic alliances to leverage each other’s strengths and accelerate innovation.
“KraitArray was engineered from the outset to unlock the full potential of agile and uncrewed platforms,” says Paulie McCartan, Head of Undersea Products at SEA. This collaborative spirit is fostering a dynamic ecosystem where rapid prototyping and iterative development are the norm.
The Data Challenge: From Sensing to Understanding
Collecting vast amounts of underwater data is only the first step. The real challenge lies in processing and analyzing that data to extract meaningful insights. Artificial intelligence (AI) and machine learning (ML) are playing an increasingly important role in this process. AI-powered algorithms can automatically identify and classify underwater sounds, detect anomalies, and predict potential threats.
Pro Tip: Edge computing – processing data directly on the USV rather than transmitting it back to shore – is becoming essential for reducing latency and bandwidth requirements. This allows for faster response times and more efficient operations.
Future Trends to Watch
Several key trends are poised to shape the future of underwater sensing and uncrewed maritime systems:
- Increased Autonomy: USVs will become more autonomous, capable of making decisions and adapting to changing conditions without human intervention.
- Swarming Technology: Deploying multiple USVs in a coordinated swarm to cover larger areas and enhance detection capabilities.
- Hybrid Systems: Combining USVs with AUVs to create a layered sensing network. AUVs can dive deeper and collect more detailed data, while USVs provide a surface communications relay.
- Quantum Sensing: Emerging quantum sensor technologies promise to dramatically improve the sensitivity and accuracy of underwater detection.
The global market for uncrewed maritime systems is expected to reach $9.5 billion by 2028, according to a recent report by Market Research Future. This growth will be fueled by increasing geopolitical tensions, the need to protect critical infrastructure, and the growing demand for environmental monitoring.
