The yellow ball sensor in the bottom is an passive hyperwave imaging sensor - a phis, pronounced "fish". Essentially what it does is image the systems within a ship that use forcefields, especially those using exotic materials for midspace-related applications. So the Massacre can use the system to scan how many drive shunts, power convertors, zero point systems, etc, are in a target, and in what configuration. Very useful for identifying targets, and for detecting whether they are armed or not.
The ball sensor might give you a clue to what inspired the Massacre...
As an indication of the heavy hitting nature of the Massacre, consider that in the Samurai render it could just about carry six drift bombs. They're not easy to see, but trust me, there are six of the things packed in under the tail, and that's about all that will fit there. In this pic, the Massacre is carrying twenty four of the same weapon. That would be a "max load", with a normal combat load being about half that - but that's still double the number the Samurai can carry.
