Tank's Hard kill Active Protective System

Active protection system suitable for light to heavy vehicles. Attacks from various threats are detected and intercepted in the immediate vicinity of the vehicle – before they reach their target.

 Russia Areana    

The Arena defense aid suite (DAS) was developed by Russia around 1993 and it was the first Active defence to have a hard kill, this system belongs to the latest generation of Russian APS. Arena's direct predecessor was Shatjor APS that was installed on the experimental Obiekt 478M MBT. Both systems have been designed by the Kolomna-based Engineering Design Bureau (KBP) together with other allied enterprises.Arena is intended to protect tanks from antitank grenades and ATGMs, including some variants of top-attack ATGMs.

In combat mode, the radar continuously searches for incoming projectiles. Once the threat is detected the radar switches to the target tracking mode, in which the data on the moving target is obtained and entered into the computer, which uses it to select the most appropriate silo and determine the time for its activation. At the determined moment, the computer generates command signals to the selected protective ammunition. The later is launched upwards and detonates, creating a directed stream of destructive elements which destroys any target within this field, eliminating the shaped-charge effect of the threat or reducing it to levels that are not dangerous to the tank.In emergency the commander (operator) can manually operate and detonate protective ammunition from the control panel.  



Trophy active defence system is a situational awareness and active protection hard kill system that operates in three major stages: Threat detection and threat tracking followed by hard kill countermeasure (Multiple Explosive Formed Penetrators – MEFP) activation and threat neutralization.  The neutralization process takes place only if the threat is about to hit the platform  The Trophy system is adaptable to any combat platform.  

Once a platform is chosen, a short trade study is completed to work out any integration issues that may arise.  Numerous elements are taken into consideration for each vehicle variant or type. For vehicles with relatively basic or light armor, e.g. the Stryker, the Trophy provides full protection against all types of RPG (as well as other threats) due to the fact that the Trophy destroys these types of threats without detonation.  

  ‪Bright Arrow APS & RCWS‬   ‪

Bright Arrow is a combined hard and soft kill active protection system (APS) and remote-controlled overhead weapon station. Based on proven Iron Fist sensing, jamming and intercepting technology, Bright Arrow integrates firepower, survivability and situational awareness into one system with weight, volume and power constraints designed specifically for light combat vehicles.‬    ‪

Bright Arrow utilizes a sensor suite and remote fire capability to rapidly detect, engage and overmatch threats typically encountered during military missions. The sensor suite provides robust detection capability of anti-tank threats and small arms bursts. The soft kill layer is based on a directional electro-optical jammer to engage a threat’s tracking and sensing behavior. The interceptor-based hard kill layer protects against close-range anti-tank rockets and guided missiles by physically destroying or deflecting the threat a safe distance from the defended platform. The blast interceptor effectively destroys or deflects an incoming threat with minimal fragmentation, minimizing collateral damage or injury to nearby personnel.‬


Iron Curtain  

Iron Curtain is an Active Protection system (APS) that defeats many of the most challenging armored vehicle threats. It was developed by US, it uses a C-band radar to detects and tracks an incoming round, alerting the system and switching it from armed-ready to an armed state.   

At close range, a distributed optical sensor classifies the threat to select aimpoint and determine which countermeasure (CM) to fire.  

The CM acts straight down, killing the threat with minimal collateral damage to personnel in close proximity.  

Quick Kill  

Quick kill is developed by Raytheon. The system consists of a multi-mission, fire-control radar that detects and tracks incoming threats, combined with hard-kill countermeasures that serve as a hit avoidance system, enabling multi-tracking and multi-engagement of enemy fire for vehicle and squad protection.  

The system's vertical launch countermeasure is unique in its ability to engage threats fired from any angle or elevation, providing all weather, full 360 degree hemispherical vehicle and crew protection with each countermeasure.  

  South Korean KAPS    

KAPS was developed by south korea for their K2 tanks, The APS consists of a three-dimensional detection and track radar, heat detection and track system, control computer, launching system and counter rocket, it is said  that it only takes three-tenths of a second for the new system to detect and track anti-tank missiles and rockets fired from enemies and fire its counter rockets to hit those missiles.  

It’s not quite as glamorous as Russian and Israeli hardkill protection systems, and the system is nearly one tenth the estimated cost of an entire K2 tank (Around $8.5 million USD).

  Germany AMAP-ADS  

AMAP-ADS is an active protection system  developed by the German company, it is suitable for light to heavy vehicles. Attacks from various threats are detected and intercepted in the immediate vicinity of the vehicle – before they reach their target. As fragments are not generated the risk of collateral damage is minimised. 

The system provides 360° azimuthal multi-hit protection up to a hemispherical cover. 

With a total weight of only 70 to 600 kg, depending on vehicle type, it is possible to mount AMAP-ADS in theatre within 2 hours and even apply the system to light vehicles. 

Due to the very short reaction times AMAP-ADS defeats threats with velocities of up to 2000 m/s and those that are fired at very close distance.  

  Sweden LEDS 150    

LEDS-150 is a progression of the LEDS-100 active defence system.  It typically consists of laser-warning sensors (LWS), an Active Defence Controller (ADC-150), a combination of passive and active Sensors and High-Speed Directed Launchers (HSDL).  This allows the combined application of active signature management, soft- and hard-kill countermeasure deployment capability to the platform.  Also included in the suite are optional displays and special-to-installation interconnecting harnesses. 

The hard-kill feature of the LEDS-150 product is characterised by its capability to physically destroy the efficiency of the terminal ballistic capability of attacking munitions without residual penetration of the protected vehicle. 

The hard-kill system detects and tracks multiple threats and calculates whether the attacking munitions will hit the platform or not. The system determines the best inertial intercept position and provides the slew and firing commands to the launchers. 

The Mongoose-1 countermeasure missile is launched at a predetermined time to intercept and neutralize the detected munitions off-board at a distance of between 5–15 m from the vehicle to minimize collateral damage to own forces.
