A Son'a vessel created specifically to collect rejuvinating, metaphasic radiation particles from the Ba'ku homeworld.

In 2375, the collector was deployed in orbit of the Ba'ku's planet. Captain Picard managed to stop the collector before it could complete its mission, by beaming over to the ship and using his phaser rifle to ignite the exhaust.

The collector was destroyed, along with its creator, Ru'afo.
