The USS Raven (NAR-32450) was a 24th century Federation Raven-type exploration vessel. On her last mission, the Raven had three crewmembers: the exobiologists Magnus and Erin Hansen and their daughter, Annika.
In 2354, on stardate 32611.4, the Hansens took the Raven on a field mission to locate and study a rumored race of cybernetic beings from beyond the Romulan Neutral Zone known to the peoples of the Beta Quadrant as the Borg.
The Raven (under the alias Jefferies) departed Drexler outpost. At the outpost, the Hansens didn't file a flight plan. They set a course for 234 mark 74. This was the last time that the Federation had contact with the starship. This information was recorded in the logs of Deep Space 4. It was later determined that after leaving the station, the Hansen family had disobeyed a direct order to return and had crossed into the Neutral Zone as part of their study into the Borg.
On stardate 32623.5, after tracking stray readings and sensor echoes for eight months, the Hansens were able to locate a Borg cube. On stardate 32629.4, the ship was pulled into a transwarp conduit while trailing the cube and emerged in the Delta Quadrant.
During the third year of their study of the Borg, in 2356 on stardate 32634.9, an ion storm damaged the vessel's multi-adaptive shielding. The shields went off-line for 13.2 seconds. The Borg detected and began to pursue the Hansens. Some time after stardate 40840.211, while attempting to reach a class M planet, the Hansens and their daughter, Annika, were all assimilated. The ship itself was also partially assimilated before crashing onto a moon in B'omar space. (VOY: "The Gift", "The Raven", "Dark Frontier")
The vessel's Borg components continued to emit a resonance frequency despite its damage. This resonance frequency drew Seven of Nine, who had once been Annika Hansen, to the vessel in 2374. Shortly afterward, the vessel was destroyed by B'omar forces. (VOY: "The Raven")
The USS Raven exists in the Activision FPS game Star Trek: Voyager - Elite Force developed by Raven Software as a multiplayer map patterned after the floor plan of the Raven Software developer's studio in Wisconsin. The floor plan of Raven Software has appeared in several of the games they have developed, including Soldier of Fortune and Soldier of Fortune II/Double Helix.
The design of the Raven also appears in Star Trek: Armada II, as a colony ship.
