Mercury Auxiliary Deflector Dish
The Oracle class has a secondary deflector-like structure built into the sensor module. This is not used as a navigational deflector per se, but should the main deflector become inoperable, with conversion work it could be used to function in that capacity. Its primary use is for the generation of particle beams that would normally require extensive modification to the main deflector dish, generally for use in scientific experiments involving spatial anomalies, or scanning through unconventional means that are not covered by the Oracle array’s sensor palettes. The auxiliary dish is located on 28 and powered from the same location.
