The Panther destroyer fleet has been "grounded" following anomalous readings from the Automated Ship Monitoring System (ASMS). This system monitors a huge number of ship measures including vibration of components, stress levels, heat et cetera and automatically transmits the telemetry data to DDS Engineering on Solaris via Open Architecture. It is thought that on two ships heat levels near the hyperspace generator and main engine harness were regularly passing DDS safety margins.
The Panther fleet (which at the moment is only 3 examples though 1 more is currently on proving trials) will have extra coolant systems installed as well as more temperature sensors in modifications which will take a few days to complete per ship. However this does raise eyebrows as to current DDS designs as the Rome class has also recently had problems which have needed emergency modifications.
