The DDS have begun to introduce a new generation of infra-red sensors with much higher sensitivity and resolution to existing sensors which provide a useful part of a ship's sensor suite. Coupled to improvements in real-time image processing and targeting information the DDS say these new sensors will improve the detection of cloaked ships (many cloaks still leave a very slight IR signature) and improved accuracy in combat situations.
Upgrades to IR sensors across the fleet have already begun and will be fitted to ships as they go through scheduled refits and repairs. The new sensors are plug compatible with the old ones so upgrading literally takes only a few hours per ship.
