The Active Defence System

The modern standard for 360° protection

The active protection system ADS combines both performance and innovation whilst being designed to be flexible enough to use on a wide range of vehicles from light to heavy. With seamless and ultra fast interaction between its high-tech system components ADS is capable of countering a wide range of attacks. Threats are detected, discriminated and intercepted in the immediate vicinity of the vehicle thereby ensuring that the chances for collateral damage are reduced to a minimum.

Video: System Description
  • Short reaction time

    Detects, recognises and neutralises threats in less than one millisecond.

  • Short range

    Capable of defeating threats fired from distances of less than ten metres.

  • Multi-Hit

    Offers countermeasure redundancy by overlapping sensor fields of view and countermeasure fields of action.

  • Reduced collateral damage

    Defeats the threat in the immediate vicinity of the vehicle ensuring a significantly reduced damage area in comparison to an actual incoming threat detonation.

  • High weight efficiency

    Offers a high level of protection with small add-on weight.

A safe investment for the future

The whole process from detection to defeat happens so fast that protection is also ensured against threats fired at short distances from the vehicle. The 360° all around protection provides security in urban operation scenarios as well as in other complex theatres. Its flexibility and capability to be modified to cater for new threats is something which is not provided for by any kind of passive protection.

Functional Principles

Early Warning

50 - 200 m/sec / 10 m – 35 m till impact

  • Detection and classification of threat
  • Prewarner
  • Multiple threats scenario is covered
  • Softkill activation

Specify and Confirm

10 m/sec / 2 m till impact

  • Electro-optical sensors
  • Near field system selects countermeasure
  • Optimum intercept solution


4 m/sec / 1 m till impact

  • Countermeasure
  • Hard kill
  • Disable threat


Anti-Tank Guided Missiles

Heavy anti-tank missiles with mono and tandem warheads. Different guidance systems (e.g. wire or beam riding) allow reliable firing ranges > 1.000 m. Very high passive armor penetration capabilities. Some with overflying top attack features.


Anti-Tank Rocket

Shoulder launched light anti-tank rockets without guidance. Typical firing ranges of 15 m – 200 m. Designed for usage in close ambush situations against APCs and IFVs. Requires direct hit to ignite.

ADS Components

Prewarner Sensors

Prewarner Sensors

The primary circle of sensor data is provided from phased array, multiple high frequency antennas. Powerage is very low in order to minimize the possibility to interfere with the sensor and to just provide the necessary data for the threat classification and exact trajectory prediction.

Electro Optical Sensors

Electro Optical Sensors

The secondary and inner circle of sensor data will confirm the imminent collision of the threat with the platform. The high degree of accuracy in close vicinity of the vehicle is key for the correct selection and steering the hard kill.



The hard kill component of ADS is the optimized effector to disable the warheads of threats prior to impact or ignition. Reduced collateral damage is a key design element. The optimization of different countermeasures is ongoing engineering work at ADS GmbH.

Distributed and Modular Active Protection

The ADS is consisting of two independant sets of sensors and several designs of countermeasures. Sensors and countermeasures get distributed alongside the vehicle in order to provide overlapping coverages and redundancies. The flexibility in the integration of the ADS provides the opportunity to use it from light armored vehicles to MBTs. Engineering support for the interconnection and hardware installation is provided by ADS GmbH. Electrical interferences to other sensors or between several ADS are avoided. ADS can be used as a modular system (‚fitted-for‘) with the advantage of interchangability between different platforms.

ADS can get installed as an upgrade to existing platforms or deeply intergrated in the concept phase for new vehicles. The system provides interfaces and information to other digitized equipment of the platform in order to optimize the situational awareness (BMS, cameras, weapon stations, softkill launchers, turrets, flash or noise detection). The system architecture provides growth potential for future customer developments (new threats, new functions, new software). ADS GmbH is constantly optimizing the system engineering and supply chain for its fielded products.
