The Target Designation Sight (TDS) provide means for optical investigation, target designation and weapon firing. The TDS is equipped with binoculars and the latest version includes a Laser Range Finder.
Bearing and elevation data are fed into the CMS system but the TDS can also be used for emergency control of a gun or CIWS system.
Variants exist for single mountings on port, starboard, fore or aft configurations, or as dedicated pairs or sets.
The importance of the function of the TDS is re-emphasised against asymmetric tactics such as piracy and insurgency.
