The USS Erebus (NCC-72435) was a Federation starship that was in service to Starfleet in the early 25th century.
In 2401, the Erebus participated in Frontier Day celebrations near Sol Station. Along with the rest of the fleet, it was seized by the Borg Collective after its younger crew were assimilated by a Borg signal transmitted via Jack Crusher. (PIC: "Vox")
Erebus is the deity personifying darkness in Greek mythology, famously lending his name to the HMS Erebus, the 19th century Royal Navy bomb vessel which took part in John Franklin's lost expedition to the Canadian Arctic.
This starship was only mentioned in writing.
This ship was identified by Dave Blass as a Nova-class. [1] Not featured onscreen beyond the graphic reference, an individual identification promosheet of the vessel was afterwards created by Keene Sin for franchise publication purposes. [2]
