Federation holoship

The Federation Holoship was a prototype starship of Federation design first launched in the mid-2370s. 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 a multitude of long-range transporters and cloaking device.

The Federation Holoships outward design was that of a rectangular vessel, approximately 247m in length, containing a forward mounted bridge module, and warp nacelles set into the main body.

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)
