Carina Arm

Location of the Carina Arm subsection.

The Sagittarius-Carina Arm, sometimes merely referred to as the Sagittarius Arm, is one of the spiral arms of the Milky Way Galaxy. As its innermost end connects to the central bar of the galaxy, it is one of the two major arms of the Milky Way. The region of the Milky Way identified as the Carina Arm is actually a subsection of this galactic region.

The space adjacent to the Sagittarius Arm, in the direction of the Orion Arm was known to be a lonely expanse, mostly devoid of populated star systems. The gulf between Sagittarius and Orion was the patrol route of the USS Excelsior in 2285, and the location of the Ajir Empire and the Grond Protectorate that Excelsior contacted on that date. A similar region of space nearby was the Great Rift, explored by the USS Marignano in 2369. (TOS comic: "Double Blind, Part One"; TNG novel: Intellivore)

During the Borg Invasion of 2381, the USS Aventine and USS Enterprise-E investigated a series of subspace tunnels centralized in the Azure Nebula. One of the tunnels exited the Aventine into the Delta Quadrant halfway between the Carina Arm and the Perseus Arm; another one stranded both vessels on the outer rim of the Carina Arm near the meridian between the Delta and Gamma Quadrants, where they faced a Hirogen fleet.

The Norolob were a species native to the Carina Arm, and in the 27th century they acquired quantum slipstream drive and their empire subsequently conquered half of the Federation's Carina Arm sectors. This led to a resistance movement forming and toppling the Norolob's government, from which the Norolob Republic arose and became one of the Federation's staunchest allies.
