A Danube-class runabout from Deep Space 9 that Ezri Dax took without orders in 2375 to search the Badlands for Worf, and which was destroyed by Jem'Hadar fighters.
The USS Gander is a runabout assigned to Deep Space 9 late in the Dominion War. It appears in the episode Penumbra, set in 2375.
When the Klingon ship Koraga is destroyed near the Badlands and Worf is listed as missing, the search is called off after three days. Ezri Dax, troubled by Jadzia's memories of him, takes the Gander without permission. She shuts down the engines and lets the plasma currents carry her along the path an escape pod would have followed, and so finds Worf alive.
On the way home two Jem'Hadar fighters attack. Worf and Ezri beam down to a planet in the Goralis system just before the Gander is destroyed, and they are later captured there by the Breen.
