The Satarran starship was a small spacecraft used by the Satarrans. It could be piloted by one person and lacked discernible armament. However, it was equipped with an advanced sensor system that could remotely access the optical data network of a Federation starship, penetrate its shields, and alter computer records and memories.
In 2368, one of these vessels was used by a Satarran agent to gain access to the USS Enterprise. The ship was destroyed after the Satarran had insinuated himself among the Enterprise crew. (TNG: "Conundrum")
