Seven of Nine's ship
Seven of Nine's ship was a small one-person starship piloted by Seven of Nine. This ship did not broadcast a transponder signal.

In 2399, this ship came to the aid of La Sirena in her battle with Kar Kantar's antique Bird-of-Prey at Vashti. It was subsequently crippled by Kantar's ship and smashed into pieces on the security net surrounding the planet. Seven of Nine was safely beamed aboard La Sirena before her ship was destroyed. ()
