Technical data
Location of holo-emitter power gnerator
Conceptually similar to a Federation holoship, it was equipped with Starfleet holo-emitters, which served as an independent sub-system with its own power generator. They were protected by three layers of ablative armor.
Such a vessel could be hidden from sensors by the implementation of a scattering field, which was otherwise denoted by elevated plasma readings, and could be pinpointed by scanning for a polarized EM signatures.
This class possessed phasers, shields, and were capable of operating in a stealth mode.
It also possessed transporter technology, and escape pods, which could not be launched at warp. Hirogen sensors could detect residual ion emissions.
Hirogen vessels produced an ion wake approximately five thousand meters long. Inside it, there was too much interference for their sensors to detect anything.
