With increasing challenges posed by illegal activities, evolving threats, and unpredictable maritime conditions, coastal surveillance is a complex yet critical mission. Thales' CoastShield solution delivers real-time intelligence, long-range detection, and seamless sensor integration, ensuring early threat identification and enhanced situational awareness to safeguard Exclusive Economic Zones (EEZs) and national security interests.

How can authorities secure vast coastlines and detect hidden threats in real time? CoastShield provides next-level maritime surveillance. 

CoastShield combines AI-driven intelligence, multi-sensor integration, and real-time surveillance to protect coastlines, from the shore to the open sea.

Coastal Maritime Surveillance - Thales

Coastline Security: The Growing Challenge

Coastal surveillance has always been an essential yet challenging mission. With vast shorelines, unpredictable weather, and high-density maritime activity, detecting illicit operations hidden among legitimate maritime traffic is becoming increasingly difficult. Illegal, Unreported, and Unregulated (IUU) fishing, smuggling, and unauthorised vessel movements threaten national security, economic stability, and environmental sustainability. 

Traditional monitoring methods often struggle to detect these threats in real time. Standard radar and surveillance systems can fail to identify small, fast-moving, or low-profile vessels, leaving authorities with critical blind spots. In today’s evolving security landscape, national agencies require an advanced, automated solution capable of 24/7 threat detection and rapid response coordination. 

Thales has developed CoastShield to address these challenges, providing a comprehensive coastal surveillance system that offers unmatched detection range, AI-driven analysis, and seamless integration with national security infrastructure. 

CoastShield: Seeing Through Maritime Clutter from the Shore to the Open Sea 

Designed to support coastal nations, CoastShield is at the forefront of next-generation maritime security, delivering real-time intelligence, automated threat tracking, and AI-enhanced situational awareness. 

At the heart of CoastShield, the CoastWatcher 100 radar enables: 

  • The detection of small targets at long distances, covering surface activity up to 100 nautical miles (NM).
  • Monitoring low-altitude airspace, identifying aerial threats near coastal zones.
  • 24/7 real-time surveillance, ensuring continuous protection of national waters and Exclusive Economic Zones (EEZs). 

Seamlessly integrating multiple sensor types into a unified Control Center, CoastShield provides authorities with a real-time, high-resolution maritime picture. This fusion of data enables security forces to detect, track, and assess threats with greater speed and accuracy than ever before. 

Thanks to its user-friendly AI-powered interface, CoastShield transforms complex surveillance data into clear, actionable insights. Authorities can quickly assess risks, coordinate responses, and deploy the necessary resources both on land and at sea, ensuring that every decision is based on the latest intelligence. 

Detecting Abnormal Activities in Real-Time 

CoastShield’s customisable alert system enables security agencies to set specific monitoring criteria tailored to high-risk zones, suspicious vessel types, or predefined movement patterns. By establishing dynamic risk thresholds, the system automatically flags unusual activity, allowing operators to respond before the threat escalates. 

In addition, CoastShield is integrated with existing maritime surveillance infrastructures, ensuring that operators always have an up-to-date, unified operational picture. By leveraging existing investments while enhancing detection capabilities, CoastShield empowers national agencies to maximise efficiency all whilst minimising costs. 

Scalable and Modular for Tailored Coastal Protection 

Every coastline presents unique security challenges, requiring flexible and scalable surveillance solutions. CoastShield is designed to adapt to various operational needs, from single-site coastal stations to fully integrated national surveillance networks. 

Depending on requirements, CoastShield can be delivered as a turnkey solution, including:

  • CoastWatcher 100 radar, ensuring long-range detection.
  • Control towers and communication networks for secure data transmission.
  • Power supply and civil infrastructure, enabling remote deployments. 

For nations requiring wider surveillance coverage, CoastShield can be expanded into a multi-station network, connecting multiple coastal monitoring sites via voice and data communication links. This approach ensures continuous coverage along vast coastlines, providing a cohesive national defense framework. 

With long-term support and upgrade services, Thales ensures that CoastShield remains operational, up-to-date, and fully optimised to counter evolving maritime threats. 

Redefining Maritime Security with CoastShield 

Coastal security is no longer just about monitoring known threats—it is about anticipating risks, automating response coordination, and ensuring seamless intelligence sharing. CoastShield’s integration of real-time AI analytics, multi-sensor technology, and advanced radar tracking provides a powerful, future-proof solution for coastal surveillance. 

With the rise of sophisticated maritime threats, security agencies must stay ahead of evolving challenges. CoastShield offers: 

  • Unmatched detection range, securing vast maritime areas
  • AI-powered anomaly detection, reducing operator workload and improving response times
  • Scalable and flexible deployment, allowing for customised national security solutions

By equipping security agencies with actionable intelligence and real-time situational awareness, Thales is enabling nations to safeguard their coastlines with confidence and precision. 

More eco-friendly technology tend to perform better. The circular economy is pushing us to optimise everything we can. It’s a powerful driver of excellence in design.
