Omekla III was the third planet in the Omekla system. This Cardassian Union world was the site of a minor shipyard.
In 2371, Thomas Riker set course for the shipyards at Omekla III after he destroyed Cardassian Outpost 47 with the stolen USS Defiant.
Riker's strategy changed after the ship was damaged by Major Kira Nerys, and the Defiant was forced to take cover in a nebula while undergoing repairs. Following the completion of repairs, the Orias system became the ship's new target. (DS9: "Defiant")
According to the Star Trek: Star Charts, on page 46, the Omekla system consisted of a Class M star. Magnitude of this star was +3, which was 10 times brighter than Sol. This system was located in the Alpha Quadrant.
