The Helaspont sector is a region of space in the Milky Way Galaxy's Alpha Quadrant. It contains part of the Helaspont Nebula, Federation space station Helaspont Station, and a section of the Federation-Tzenkethi Coalition border. (ST reference: Star Charts; DS9 novel: Sacraments of Fire)
In September 2385, the USS Argus, under the command of Captain Aldany Menzies, was assigned to patrol the Federation-Tzenkethi border in the Helaspont sector. It provided twice daily status updates to Helaspont Station on the far side of the sector.
