9LV FCS - Fire Control System

Optimal Weapon Control Onboard

The 9LV FCS provides extremely efficient all-weather fire-directing capability for any naval gun or a wide range of missile systems.

With its open architecture software modules, the 9LV FCS together with the CEROS 200 director, forms a fire-control unit that integrates with any system, whether recently ordered or already onboard.

World-class performance

For operators, the advantages of the 9LV FCS – Fire Control System – are to be found in the world-class performance in terms of acquisition speed, tracking and precision, combined with the supporting software modules to outsmart any threat.

REACTION TIME

The 9LV FCS can designate, track and be ready to fire within less than a second. Using smart filtering, target acquisition and engagement can start immediately after designation.

MULTIPLE TARGETS

The 9LV FCS features a range of manual, automatic and semi-automatic modes for controlling sensors and weapons. Along with advanced tracking capability, this allows effective handling of high-pressure, multiple target scenarios.

Becoming a customer

As a customer of Saab’s you benefit from a complete life commitment. It is our utmost ambition to support and facilitate your use of our products and services. That is why we are always willing to walk that extra mile to develop a strong and trustful relationship.

Features

With world-class performance in terms of acquisition speed and tracking precision, combined with the ability to track any target in any weather, 9LV FCS offers you the advantage of full performance against any threat, including asymmetric threats in littoral environments.

World-class performance

For operators, the advantages of the 9LV FCS – Fire Control System – are to be found in the world-class performance in terms of acquisition speed, tracking and precision, combined with the supporting software modules to outsmart any threat.

The flexibility of the FCS and the 9LV modular open architecture provide advantages for the design of modern naval ships as well as for the upgrade of existing systems.

Optimal weapon control onboard The system is available in a CWI configuration with the 9LV ESSM missile-control module. This version has been delivered to the Australian and New Zealand ANZAC frigates and the Danish Standard Flex, and provides an X-band channel for CW illumination of a target for guidance of the semi-active surface-to-air missile.

9LV FCS can also be combined with the 9LV gunfire-control and SAM modules that provide precision control for any naval gun or fire-and-forget SAM missile system.

Optimal weapon control onboard Several CEROS 200, EOS 500 electro-optical tracking systems, gunfire-control and missile-control modules can be combined in a weapon-control subsystem, where operators dynamically allocate any combination of tracker and weapon for flexible handling of surrounding threats.

For optimal performance, the 9LV Defence Coordination Suite is available for performance-based engagement optimisation of incoming threats.

The versatile associated director, CEROS 200, tracks supersonic missiles as well as surface targets extremely close to the ship. This offers the advantage of full performance against any threat, including asymmetric threats in littoral environments.

The optional 9LV human-machine interface, which provides full control of all 9LV FCS features, will run on any modern multi-function console.
