It has the usual main navigational deflector on the front of the engineering hull and an auxiliary deflector on the front of the saucer similar to the USS Voyager
or the lesser-known Nova
class. For the Grandeur
the aux deflector has slightly greater significance for reasons that have not yet been revealed.
There is also some debate about whether the aux deflector would be powered under normal circumstances. If I'm not mistaken, I think Voyager's
was rarely, if ever, lit. But we'll have to see how that one shakes itself out.
