The Enterprise NX-01 captured a small cell ship while rescuing Klaang, a Klingon courier, in April 2151. (ENT: "Broken Bow") Commander Tucker spent months studying the ship, especially its cloaking device, with very little success. In 2152, the captured ship was used to mount a rescue mission on a prewarp planet. Although Commander Tucker believed that he had finally figured out how to operate the cloaking device, he was distressed when the cloak began to fail shortly after their launch. It was then that he realized that power was being drawn from the cloak to the weapons nodes, which he had previously deactivated. Tucker surmised that the nodes were programmed to automatically come back online upon the ship's launch. Despite this, Tucker was able to re-engage the cloak. (ENT: "The Communicator")
The cell ship plays a key role in the "Daedalus" books. While preparing the ship for a mission to analyse a unique spatial anomaly in the vicinity of a planet with a pre-warp culture, Enterprise is attacked by aliens from a parallel universe, with Tucker and Hoshi Sato being the only two who escape the attack by using the ship's cloak to escape via the shuttlebay as they were carrying out work on the ship prior to the attack. Having reunited with the rest of the Enterprise crew, and helping to resolve a crisis in that universe, data acquired from the ship's sensors — Enterprise's sensors having been damaged during the crossover between universes and thus unable to provide the necessary information — allows Enterprise to determine the exact conditions in their universe of origin and return home via the anomaly.
