The Zemba-class dropship was a small craft used by the Romulan military to deploy ground troops.
The warbird IRW Draco carried a complement of Zemba-class dropships during the Dominion War. Shinzon and several Reman soldiers used the dropships, including the Zdonek, to land on Goloroth in 2375 to engage Jem'Hadar troops. (ST short story: "Twilight's Wrath")
