The Leeds was the Nebula-class vessel seen during the DS9 opening credits in seasons 4-7. While the registry number and name are not visible in the appearances on screen, the model of the ship used has been photographed bearing these markings. Michael Okuda has stated that, during the credits sequence, the Leeds model appeared on screen with that label. Other appearances of otherwise unidentified Nebula-class vessels (e.g. DS9: The Visitor、Profit and Lace、Doctor Bashir, I Presume and Sacrifice of Angels) have not been associated with the USS Leeds.
