Universal sight and fire control system
The modular design of UTAAS offers the user a variety of performance options and upgrading possibilities. The beam paths for all channels go through the same aperture, offering good system stability and no need for realignment.
Independent line of sight
This principle enables the operator to retain the target in the centre of the reticle during the entire aiming and laser range-finding sequence. No re‑aiming is needed. Gun-laying is automatically controlled by the fire-control computer.
The design of the top module allows large deflection angles in both azimuth and elevation to be achieved. These are essential for effective combating of fast aircraft.
Options
The low-hazard laser rangefinder has a variable repetition frequency, which can be configured for various operational requirements. Various methods of anti-laser eye protection can be employed in the sight.
For night and all-weather operation, the system can be equipped with a range of third generation thermal imagers.
The system can be customised for various weapon systems and integrated with command and control systems. It also has an interface to smart ammunition programming units.
In use
Saab has designed and delivered fire-control system (FCS) packages for infantry fighting vehicles and main battle tanks for many years. Today the UTAAS is in service in Sweden, Norway, Switzerland, Finland, the Netherlands, Denmark and Estonia, all with the Combat Vehicle 90.
