In 2375, the holoship was employed by Admiral Doughtery and Ru'afo to secretly transport the entire 600 Ba'ku inhabitants off the Ba'ku planet without their knowledge in order to obtain the metaphasic radiation inherent in the planet's rings.
The ship was cloaked and placed at the bottom of a lake, located near the Ba'ku village. It was later detected by Starfleet personnel, unaware of its presence, due to strong neutrino emissions coming from the lake.
It was later brought back into the planet's orbit, by Lieutenant Commander Worf, where it was used to transport the command crew from the bridge of Ru'afo's flagship. This feat allowed Gallatin and Jean-Luc Picard to disable the nearby Son'a collector. (Star Trek: Insurrection)
Built specifically to serve as a transportable holodeck used to create holographic environments to simulate the surroundings familiar to the holoship's passengers. It was also equipped with fourteen long-range transporters and a cloaking device. (Star Trek: Insurrection)
The idea of surreptitiously transplanting an indigenous people by use of the holodeck had already been explored in TNG: "Homeward" when a group of Boraalans were transplanted in the holodeck of the USS Enterprise-D without their knowledge to their new homeworld as their own world became uninhabitable. The concept of the holoship might have stemmed from this incident.

The novel Section 31: Abyss, by David Weddle and Jeffrey Lang, establishes that the holoship was created by Section 31 for the Ba'ku incident, which the organization had engineered and had publicly blamed on Dougherty. The holoship was slated for destruction by Starfleet Command after the incident became public; however, Commander Elias Vaughn and his cabal of Starfleet officers covertly working against Section 31 stole the ship and faked destruction reports, later using it to help undermine various Section 31 operations.
