A shuttlepod
The Prometheus shuttlepod was a Federation type 15 shuttlepod assigned to the Template:ShipClass USS Prometheus in mid-2370.
That year, Professor Gideon Seyetik departed from the Prometheus aboard this shuttlepod, which he had loaded with protomatter, and proceeded to crash it into the surface of Epsilon 119, and successfully igniting the dead star. (DS9: "Second Sight")
