Editing Valour-class frigate (section)

=== Electronic systems and sensors ===
40% of each vessel's costs are related to the combat-management system installed on the Valour class, with 75% of the combat suite being developed in South Africa.

The frigates mount a Thales Naval France MRR-3D NG G-band multi-role surveillance radar which is a lightweight phased array antenna that operates as both a surveillance radar and a self-defence system sensor with automatic mode switching. The MRR-3D NG in surface mode can detect low and medium-level targets at ranges of up to {{cvt|140|km}}, and in long-range 3D air surveillance setting up to 140&nbsp;km. For self-defence, any threat within a radius of 60&nbsp;km can be detected and tracked.

Two Reutech RTS 6400 monopoles X band (I/J bands) combined radar and optronic trackers are also equipped that are a high performance, domestically designed and manufactured radar tracker with a 60&nbsp;km operational range. They also mount a Teutech Electro-optical Tracker, a Tellumat Integrated Naval Identification Friend or Foe System, M-Tek Target Designation Sights, a Thales UMS4132 Kingklip Sonar, and an MDS 3060 Obstacle Avoidance Sonar.

Also included is a computer-based "Naval Logistic Management System" that controls the on-board maintenance planning and execution by automatically generating weekly check-lists and repair schedules. [[Replenishment at sea]] can take place over the bow, over the stern, or amidships. Liquid and dry goods as well as passengers weighing up to {{convert|250|kg}} can be transferred this way. Vertical replenishment via helicopters can take place over the helideck and/or the foredeck.<ref name=":2" />
