Technology

The “Metatron” project represents a comprehensive system for the protection of Israel, integrating advanced engineering solutions, technologies, and security systems to ensure the reliability and resilience of its borders. The wall and its infrastructure integrate protection from tunneling, modern monitoring and surveillance systems, and environmental and energy solutions, designed to prevent threats from various directions – from underground attacks to airborne and cyber threats.

Protective Coatings and Materials

• Anti-climb Protection
  • Smooth vertical faces without handholds, anti-climb toppings and sensor-equipped mesh along the upper edge to prevent climbing and attempted breaches of the structure.
  • Polyurea coatings and geomembranes on the underground part of the wall protect the structure from groundwater and chemical attack; detection of digging relies on the sensors described below.
• Blast and Impact Protection
  • A multilayer wall: an anti-shaped-charge screen, shells of ultra-high-performance fibre-reinforced concrete (UHPC), a reinforced concrete core and an anti-spall layer on the inner face. The wall is designed to withstand direct fire and repeated hits without collapse or a through-breach; polyurea coatings additionally reduce fragmentation and spalling.
• Seismic and Shock Protection
  • Expansion joints and energy-absorbing layers in the underground part reduce the effect of earthquakes, underground explosions and shock waves on the structure.

Sensors and Monitoring Systems

• Ground Penetrating Radars (GPR)
  • For monitoring underground activity, including tunneling and any unauthorized movement under the wall.
  • Ground-penetrating radar (for example, GSSI SIR 4000 units) is used for regular scans of the strip along the wall. Depending on the soil, it sees from a few meters to a few tens of meters deep, so it covers digging near the surface, while deep attack tunnels are detected by seismic-acoustic and fiber-optic sensors.
• Seismic Sensors
  • Seismic sensors for monitoring earthquakes and other seismic vibrations affecting the structure of the wall.
  • This will rely on standard geotechnical instrumentation: seismometers, accelerometers, tiltmeters and inclinometers, of the kind used to monitor dams, bridges and other major structures.
  • All sensors must be integrated into the overall management system and analyze vibrations and soil movement.
• Thermal Cameras and Surveillance Cameras
  • For 24/7 monitoring of all sections of the wall and detecting suspicious objects or activities, fixed long-range thermal cameras (for example, from Teledyne FLIR) will be used, providing high-quality images even in low-light conditions.
• Acoustic Monitoring
  • For detecting unusual vibrations related to attempts to tunnel, digging, or other changes in the soil structure.
  • Seismic-acoustic sensor arrays and distributed fiber-optic acoustic sensing (DAS) along the wall will be used; this technology is already applied to protect pipelines and extended perimeters.
• Pressure and Gas Sensors
  • Gas and pressure sensors to detect underground blasts and abnormal changes in the soil atmosphere.
  • Fixed gas detectors (combustible and toxic gases, oxygen depletion) and pressure sensors will be installed in the underground part, while inspection teams carry portable gas detectors.
• Motion Sensors
  • Motion sensors for detecting active attempts to penetrate or move near the wall.
  • Passive infrared sensors, microwave barriers, fence-mounted vibration sensors and, on some sections, ground surveillance radars will be used.

Automated Security Systems

• Automatic Fire Points with AI
  • For recognizing and neutralizing threats, the Rafael Sentry-Tech system, widely used for border protection in Israel, will be used. The system uses AI to classify objects (such as drones or unauthorized persons) and alert an operator; in all cases, the decision to use force is made by a human operator, and the AI does not carry out autonomous engagement of targets.
  • Firing positions equipped with sensors and controlled by operators via automated aiming systems, to ensure a rapid, human-supervised response to threats.
• Mobile Air Defense Systems
  • Protection systems such as Iron Dome by Rafael Advanced Defense Systems, used for intercepting missiles and UAVs, providing defense against airborne threats.
• Automated Reconnaissance Drones
  • Drones such as Elbit Systems’ Skylark and Aeronautics’ Aerostar will be used for patrolling and surveillance; both are used for border and perimeter monitoring. These drones are equipped with sensors, cameras, and AI for data analysis.
• Fortified Bases
  • Permanent IDF crews are stationed only at fortified bases with sally-port gates, every 10-40 km depending on the threat level, and at ecoduct nodes; there are no small fixed posts along the wall, which would be easy targets.

Energy Autonomy and System Support

• Autonomous Energy Sources
  • Solar panels and wind turbines will provide autonomous power to all engineering systems, including lighting, monitoring, cameras, and other security components.
  • Utility-scale solar panels and wind turbines from established manufacturers (for example, Siemens Gamesa turbines) will be used, of the kind applied in large infrastructure projects worldwide. For backup power, industrial battery storage systems of the Tesla Megapack class and backup generators will be used to ensure a stable and autonomous power source in extreme situations and areas where solar or wind capacity is insufficient.

Security Zones and Controlled Areas

• Zones Along the Wall
  • The wall stands entirely on Israeli territory and is not the border.
  • From the outside in:
    • the border (or, where no agreed border exists yet, the 1967 line);
    • a closed outer approach zone 300-500 m wide, which is Israeli territory and a closed military area, with a tracking strip along the border fence and a technical road along the outer face of the wall;
    • the wall itself;
    • an inner security strip at least 50 m wide, typically 100-150 m, with a sensor fence, an anti-vehicle barrier and a patrol road;
    • beyond it, ordinary land.
  • The outer road serves unmanned patrol vehicles, maintenance crews and armored response teams, which exit through double sally-port gates built into fortified bases, every 10-40 km depending on the threat level of the section; the main rapid-response line remains on the inner patrol road. In densely populated areas near the 1967 line the width of the zones varies.
  • There is no wide no-farming belt: construction and farming are restricted only within these narrow zones, and agriculture continues right up to the inner strip. The approach zone is cleared of explosive hazards once, during construction, by engineering units with standard mine-clearing equipment.
• Access Control
  • Military police, drone systems and automated monitoring systems control access to both zones. Unauthorized crossing is prohibited in both directions, including by Israeli citizens: passage is only through gates, with a crossing log subject to international audit.
  • Teledyne FLIR thermal cameras and Terma radars will be used to monitor large areas and prevent unauthorized access.
• Access Restrictions
  • Periodic satellite imaging and continuous drone observation to track movements over significant distances.

Environmental Integration

• Green Engineering
  • Multi-level eco-ducts to provide safe migration paths for animals.
• Minimization of Environmental Impact
  • The project includes systems to control the impact on ecosystems, such as monitoring flora and fauna, as well as preventing light pollution by installing energy-efficient lighting systems.

Legal and Control Systems

• International Agreement
  • Establishing the legal right to neutralize or permanently seal unauthorized tunnels detected beneath or adjacent to the wall perimeter.
  • Placement of international observers to ensure transparency and legality of actions.
• Environmental Standards Monitoring
  • Establishment of checkpoints to ensure compliance with environmental standards within the safety zone.

Costs and Resources

• Technology costs, base estimate including design and contingency:
  • Sensor systems (seismic-acoustic, fiber-optic, thermal cameras, radars): $1.4 billion
  • Satellite imagery and data: $0.6 billion
  • Operator-controlled remote weapon stations (about 300), armored patrol vehicles (about 290) and command centers: $1.0 billion
  • Cameras, UAVs, ground robots, AI: $1.5 billion
  • Cybersecurity and backup systems: $0.7 billion
• Total: about $5.2 billion, or about $4.7 million per km (range: $3.5-7.5 billion)

The budget is preliminary and approximate. It does not include the wall structure, the fortified bases or the ecoduct nodes, which are detailed in the Wall section. All financial evaluations are based on approximate equipment costs at the time of preparing the materials.

Conclusion

The “Metatron” project is a comprehensive structure incorporating many advanced solutions for the protection of Israel. The wall is equipped with multi-layered protection, modern sensors, automated security systems, energy independence, and environmental solutions to preserve the surroundings. These measures will provide a high level of protection from various threats, including tunneling, seismic impacts, and airborne attacks.

In turn, the integration of centralized management, patrolling, and technical maintenance in the “Metatron” project will ensure a high level of coordination, efficiency, and rapid response, ensuring the security and longevity of the wall throughout its operational lifespan.
