LEDS

Description: The Land Electronic Defence System (LEDS) is a vehicle-mounted countermeasures system developed by Saab. It combines active signature management with soft- and hard-kill capabilities to provide 360-degree full-spectrum active protection for land vehicles. The system has been designed with modular architecture and scalability for future growth matching current and emerging anti-armor threats. The LEDS follows a layered automated defense principle and is suitable for urban terrain operations with very short defense capability and minimal collateral damage effect. There are several LEDS variants that can be added to each other following a building block principle according to the customers requests.

LEDS-50 is the basic version and is designed to provide a vehicle's crew with situational awareness of laser emissions associated with armor threats. It consists of an active defense controller (ADC) and a number laser warning sensors (LWS-310 and LWS-500 models). The active signature management subsystem can be added to any of the LEDS versions to provide dynamic external fire protection while moving at speeds of up to 60 kilometres per hour. LEDS-100 is a soft-kill system developed for land vehicle enhanced survivability. It combines the LEDS-50 elements with a High-Speed Directed Launcher (HSDL) and fast multi-spectral smoke and optionally an infrared jammer lamp against anti-tank guided missiles. LEDS-100 system denies the threat the opportunity to effectively engage the protected vehicle.

The hard-kill LEDS-150 builds on LEDS-100 system adding the option to physically destroy the efficiency of the terminal ballistic capability of attacking munitions without residual penetration of the protected vehicle. LEDS-150 is designed to detect and track multiple threats and determines if the attacking munitions will penetrate the target or not calculating their trajectory. Moreover, the system also determines the optimal inertial interception path for the incoming threats that will hit the protected vehicle. The Mongoose-1 countermeasure missile is launched at a predetermined time to intercept and neutralise the detected munitions off-board at a distance of between 5 to 15 meters from the vehicle to minimize collateral damage.
