USS Intrepid (NCC-1631)

The USS Intrepid  (NCC-1708) was a Constitution class Federation starship with a predominantly Vulcan crew numbering about 430.

In 2268, the Intrepid worked in conjunction with Starbase 6, in conducting a mission to investigate the loss of contact with solar system Gamma 7A in Sector 39J. While traversing that sector of space, the Intrepid encountered an unknown dark zone which was, unbeknownst at the time, slowly killing the ship's crew.

On stardate 4307.1, Starbase 6 lost contact with the Intrepid. A rescue priority was issued to the USS Enterprise to investigate the loss of the Intrepid in an unknown dark zone. En route, Commander Spock telepathically sensed the crew of 400 Vulcans die.

On stardate 4309.2, the Enterprise established that the thing which destroyed the Intrepid and the Gamma 7A system was an incredibly huge but simple cellular being whose energies are totally destructive to all known life. The crew of the Enterprise destroyed the form, which was determined to be nourishing itself for reproduction.
