CBS have confirmed that their new Star Trek series will be called Star Trek: Discovery. The new series will follow a mission involving the USS Discovery (NCC-1031), a Federation starship, and will be set in the "Prime" timeline (i.e. the same timeline and continuity as the original series, The Next Generation, Deep Space Nine and Voyager).
Executive producer Bryan Fuller would not confirm precisely when in the timeline the show would be set. He previously shot down a rumour that the show would be set between Star Trek VI: The Undiscovered Country and Star Trek: The Next Generation and suggested that characters and actors from the previous shows could appear in later seasons of the new series, hinting at a post-Voyager timeframe. However, the USS Discovery is a deliberately retro design (drawing on Ralph McQuarrie's 1970s concept art for Star Trek: The Motion Picture) and its early design number suggests it's an old ship, predating even the original Enterprise. Fans have already speculated that it's an old ship pulled back into service for some reason, or the vessel is carried forwards in time as part of the new storyline.
Little else is known at the moment, save that filming starts in September, the series will consist of between 10 and 13 episodes and the show will debut in January on CBS before moving onto CBS All Access in the States. Space will air the show in Canada and Netflix will broadcast the series in most other territories.
