Saab upgraded RTN aircraft carrier H.T.M.S. Chakri Naruebet

Saab to Upgrade C2 System of the HTMS Chakri Naruebet

27 April 2012

The contract involve upgrading the aircraft carrier with the latest generation of command and control system, 9LV Mk4. Saab will also supply data-link equipment to the ship, which will allow communication between the ship and the Royal Thai Air Force’s Gripen fighter aircraft and the airborne radar system Erieye, carried by the Saab 340 AEW.

Saab is the main contractor to the Royal Thai Navy, and as well as supply of its own systems, its tasks will include procurement of third-party systems and responsibility for integration of all existing and new systems.

“This is the second 9LV Mk4 contract signed between the Royal Thai Navy and Saab. It further strengthens Saab’s position in the country, which we are proud of,” says Gunilla Fransson.

The contract mainly concerns the Security and Defence Solutions business area as

the supplier of the command and control system. The Electronic Defence Systems business area will supply the Sea Giraffe AMB surveillance radar system as well as data-link equipment for communication with Gripen and the Erieye airborne early warning systems.

The contract will run between 2012 and 2015.

Combining all the information from different sensors and UAV / UUV sources into a real time situational picture and helping the crew to react is the task of the combat management systems (CMS). Swedish company Saab’s 9LV CMS system for instance features a performance-based engagement-planning function for anti-air warfare, which is based on probability calculations and will optimise survivability by evaluating all possible threat-engagement combinations using all combinations of sensors and weapons, including ship manoeuvre.

One goal with designing today’s CMS is to fully integrate all sensors and effectors with a flexibility to allow every workstation in the operation room to perform every role. The system-architectures will become more and more fully distributed, with consoles connected via high-speed data networks, embodying commercial, off-the-shelf products. Open architecture and off-the-shelf products are also supposed to make updates easier in the future as naval vessels have life cycles of up to 30 years and today’s software and computing system up to one or two years. naval-technology.com

SEA GIRAFFE AMB radar surveillance equipment designed to be capable of detecting both on the coast and in the air precisely. Designed to connect directly combat 9LV (CMS)

The radar is able to detect the angle of 0-70 degrees to 360 degrees, covering a 180 kilometer surveillance can detect targets with high accuracy. And detect even the target object invisible. Small as well as the 3D GIRAFFE AMB radar is versatile with the ability to cover all the needs. Featured in Add the time to meet and make decisions. Low radar footprint Can observe the motion of the target by land, sea and air radar highlights three critical limit.

• Investigator in the air and can interfere with the radar track of the enemy.
• Can observe and track the motion of the enemy on the side.
• Be alert gunshot detection and neck where the bullet was fired.
• Can distinguish between different types of goals Even the up and down motion of the helicopter.
• Can pointing to fight missile defense land. Naval and air precisely.
• To support gunnery ship.
