A Jem'Hadar warship that crashes on Torga IV in 2373 and is salvaged by Sisko's crew, then flown behind enemy lines the following year to destroy a ketracel-white depot.
The vessel is first seen in the Deep Space Nine episode The Ship. It crashes on Torga IV with its crew dead, and Sisko claims it for Starfleet. A Vorta, Kilana, besieges the wreck to recover a wounded Founder hidden aboard, and by the time the changeling dies the standoff has cost several lives, including Crewman Muniz.
In A Time to Stand, early in the Dominion War, the repaired ship is used for a covert raid. The crew struggle with a bridge that has no chairs and no viewscreen, only headsets that give Sisko and Garak headaches, and they succeed in blowing up the main ketracel-white facility in Cardassian space.
The blast cripples the warp drive. In Rocks and Shoals the ship is attacked by Jem'Hadar fighters and crashes into the sea of a planet in a dark-matter nebula, where it is lost.
