In late 2371, the Hudson was modified to act as an independent scout vessel, designated a preliminary survey vessel and manned by a small crew, to support and increase the range of the Sarek's ability to chart and explore new sectors of the Gamma Quadrant. PSV/USS Hudson was the first of what was planned to be dozens of preliminary survey vessels, whose missions would be to survey a new sector and determine if it warranted the resources of an entire starship for full-scale exploration, since the Sarek was the only Federation starship assigned full-time to the Gamma Quadrant.
Starfleet's preliminary survey program was canceled after tensions between the United Federation of Planets and the Klingon Empire increased almost to the point of all-out war in early 2372 and the Hudson was damaged beyond repair by a surprise Jem'Hadar attack in the Gamma Quadrant. The Hudson was towed back through the Bajoran wormhole to Deep Space 9 and its crew was rescued by the USS Defiant (NX-74205) in mid-2372.
