USS Seeker
From Star Trek: Theurgy Wiki
The USS Seeker was a Federation starship serving in Starfleet in the late 2360's. Sar-unga Neleo, the Asurian spy served aboard the Seeker as a security specialist with the rank of petty officer second class under the alias Dyan Cardamone from 2369 to 2374.
(So far the class of the Seeker has not been revealed, but from the name it is likely an Oberth class vessel.)
