The Curie was a Federation type 6 shuttlecraft that was in service with Starfleet in the mid-24th century, attached to the USS Enterprise-D. It was shuttlecraft 03. Lieutenant Worf piloted the Curie to a bat'leth tournament on Forcas III in early 2370. While on board the shuttle, he passed through a quantum fissure which caused him to begin shifting between different quantum realities. The Curie was sent to an alternate Enterprise and reconfigured to emit an inverse warp field. Worf took the shuttle through the fissure once more, sealing the fissure and sending him back to the point in time where he first encountered the anomaly. (TNG: "Parallels" )
