The soliton wave rider was an unmanned Bilanan drone ship.
In 2368, the drone ship took part in the soliton wave rider experiment. It was towed to a position approximately two million kilometers from Bilana III. From there it was enveloped and pushed into warp by the soliton wave. The ship was programmed to send telemetry using subspace radio. The test ship transferred energy from the wave to create its warp field. After the power signature of the wave began fluctuating, the ship's warp field destabilized. This caused extreme shearing stress to the hull, resulting in the destruction of the vehicle. (TNG: "New Ground")
