LEFLASYS (ASRAD)
The LeFlaSys Light Mechanized SHORAD (Short Range Air Defence System) has been developed for the German Army by STN ATLAS Elektronik GmbH in Bremen and Krauss-Maffei Wegmann (KMW) in Kassel, Germany. The export version is known as ASRAD (Atlas Short Range Air Defence System). It is based on the Wiesel 2 carrier vehicle, which was developed by Rheinmetall Landsysteme (formerly MaK). The system provides protection of vital assets such as command, control communications and information centres (C3I centres), airfields and troops on the move, or in the battlefield against the threat of low level flying fixed wing and rotary wing aircraft.

An army platoon would be equipped with a LeFlaSys Air Defence Platoon Command Post and typically between five and eight Ozelot Air Defence Weapon Platforms. The LeFlaSys system is expected to fulfil the short range air defence requirements of the rapid reaction forces of the German Army. A series production contract has been awarded for 50 weapon platforms, ten platoon command post vehicles and seven battery command vehicles. Deliveries are planned between 2000 and 2003.

The Hellenic Army of Greece placed an order for 54 ASRAD systems in October 2000. The systems will be mounted on vehicles manufactured under license by the Greek company ELBO.

OZELOT WEAPON SYSTEM

The Ozelot Weapon System is built on the Wiesel 2 small armoured tracked vehicle. The Ozelot carries four ready-to-fire surface-to-air missiles, including the Stinger, Igla, the RBS 70 MK2 and others. Ozelot is air transportable in a CH-53 helicopter.

The main components of the weapon platform are: pedestal with azimuth and elevation; drive and combined sensor and system electronics including the missile interface; electronics; multipurpose launcher; pedestal electronics systems; control and display unit.

FIRE CONTROL

Target acquisition is achieved, either by the 3-D HARD radar installed on the platoon command post, which downloads target data via radio data link to the Ozelot weapon platform, or by the Pilkington Optronics ADAD passive infrared search and track system (IRST), mounted on the forward part of the roof.

For target tracking, the Ozelot is equipped with its own stabilised forward looking infra-red (FLIR) sensor, TV and laser rangefinder as well as dual mode autotracking. The system is capable of automatic range and envelope determination and fire control and second shot capability on the same approaching target. Remote control at up to 100 m is possible, using the same control and display unit.

In addition to the weapon pedestal, there is a navigation system with a global positioning system (GPS), inertial navigation system and north-finding gyroscope, and the C31 interface via VHF-radio for data and voice transmission.

PLATOON COMMAND POST

The purpose of the Platoon Command Post is to carry out target acquisition for 5 to 8 LeFlaSys Weapon platforms Ozelot in a range of approximately 20 km. Target data is transmitted via a radio data link to the weapon platforms in the platoon and also to other platoons. Evaluation of target data received from other sensors including allied forces, threat analysis and identification friend or foe (IFF) is carried out in the Platoon Command Post.

The Platoon Command Post vehicle is equipped with an Ericsson HARD 3-dimensional X-band radar for target acquisition and for tracking in track-while-scan mode. The range of the radar is 20 km. The radar uses Kalman filtering and Moving Target Indication (MTI). The IFF MSR 200 XE identification friend or foe (IFF) is integrated into the radar system.

The platoon command post is also based on the Wiesel 2 vehicle. The platoon leader's station and the radar operator's station are equipped with control and display units with flat panel displays for air picture data and command and control data. The command post uses advanced 64 bit computer technology for C3 air picture data processing, threat analysis and built-in test. Communication links are based on VHF radios, SEM 93 and SEM 80/90 supplied by Alcatel SEL AG of Stuttgart, for voice and data transmission.

The system's navigation suite includes a Rockwell Collins PLGR AN-PSN11 global positioning system and a Talin navigation system from Honeywell.
