An uninhabited Gamma Quadrant planet where Sisko's survey team claims a crashed Jem'Hadar warship and endures a costly siege in the Deep Space Nine episode The Ship.
Torga IV is a barren planet in the Gamma Quadrant. In The Ship (2373), Sisko leads a team there to assess its mineral deposits for mining.
A Jem'Hadar warship plunges out of the sky and buries itself upside down in the rock, its crew killed. Sisko claims the wreck as a prize for Starfleet. A second Dominion vessel arrives, destroys the team's runabout in orbit, and the Vorta Kilana demands the ship back while refusing to storm it. Trapped inside under bombardment, the officers turn on one another as the engineer Muniz slowly dies of his wounds.
The reason for Kilana's caution emerges too late. A wounded Founder was hidden aboard, and it dies. The Jem'Hadar kill themselves, and the Defiant tows the ship home.
