Saab has been awarded a contract to perform mid-life upgrade (MLU) for the Norwegian Army's ARTillery HUnting Radar (Arthur).
Awarded by the Norwegian Defence Logistic Organisation (NDLO), the SEK115m ($13.2m) contract requires Saab Technologies Norway to upgrade the radar system's sensor to Saab's current production version of Arthur (ModC).
The contract also covers development of new command, control and communication functions and integration in a new 10ft container, which has ISO corners for easy and flexible use on many vehicle types.
Saab Surface Radar Solutions business unit head Anders Linder said: "We are very happy that the Norwegian Forces take the step to the latest version of Arthur, which ensures the best possible radar for this application."
The sensor upgrade is expected to improve the system's detection range and accuracy, increase the operational flexibility and also provide mobility and protection in a highly mobile manoeuvre warfare environment.
Jointly developed by Saab Electronic Defence Systems and Saab Technologies Norway, Arthur is a C-band medium-range weapon-locating system designed for detection and location of artillery weapons within a 60km range, enabling timely and precise counter-battery fire.
Air-lifted by the C-130 Hercules and other military helicopters, the standalone radar can be mounted on any truck with an adequate payload, and features low side-lobes, making it difficult to jam.
The system is partly based on the same technology as Saab's Giraffe radar, and simultaneously scans 100 targets per minute, while tracking own shells and calculating impact points during registration.
Having entered into Norwegian Army's in 1999, the radar is currently integrated on a Hägglunds BV-206 tracked vehicle designed to support light infantry brigades.
The army will now use M113F4 armoured tracked vehicle as the main carrier for Arthur.
Development and production MLU prototype will be carried out at the company's facilities in Halden, Norway, and Gothenburg, Sweden, and delivery is scheduled to take place in 2017.
Apart from Norway, the system is also used by the Czech Republic, Canada, Denmark, Italy, Greece, Malaysia, Norway, Sweden, Spain, Singapore, as well as the UK.
