The Derf class tender became operational on Reference Stardate 1/9807 (July 2198)[1] with the commissioning of the U.S.S. Derf NCC-20100.[2] More than 500 were constructed, and although the class did not see combat during the Four Years War, which ended a month earlier, the class was responsible for repairing and maintaining navigational beacons along the new border between the United Federation of Planets and the Klingon Empire.[1] The class was also used for survey work as a medium exploration ship. The circular top hull was four decks high; the lower hull was also four decks. Decks 5-7 were 3.2 meters high, while Deck 8 was 9 meters. Derf class vessels were named after historical places in the Federation, and initially bore hull registries in the 20100-20179 range.[2]

The Derf class marked a new concept in navigational beacon repair. Before its introduction, marker buoys and navigational beacons had to be retrieved and returned to a repair facility to be serviced. Derf class tenders eliminated this need because they carried repair facilities onboard.[3] When performing maintenance on navigational buoys, early warning sensors, beacons, and communication relay stations, special shuttles with tractor beams recovered the buoys, then entered forward, where the retrieved equipment underwent an "assembly line" maintenance routine. When repaired, the shuttle then took the device out the aft door and replaced it on the navigation route.[2]

Designed and built under contract by Chandley Works Ltd., the class had a maximum safe cruising speed of Warp 6, and an emergency speed of Warp 8. The class was 274 meters long, 128 meters wide, and 65 meters high. Derf class vessels carried two 6-person and one cargo transporter, two passenger shuttlecraft, and five work pod shuttles.[4][4] Although the Derf was not designed as a fighting vessel, it was capable of aggressive defense. Most repair missions took place along the borders between the major powers, where the chances of encountering enemy ships was very high.[3] Because of this high risk, the Derf was armed with two banks of two FH-4 phasers and an FSH deflector shield.[4]

This protection does not prevent the Derf class from falling prey to enemy ships. On Reference Stardate 2/0702 (February 2207), the U.S.S. Acropolis responded to signals from a malfunctioning marker buoy. As its shuttle neared the beacon. a Klingon warship appeared and opened fire before defensive actions could be taken. The volley crippled the Acropolis' engines, and the tender was boarded and towed into Klingon territory.[3] Intelligence later discovered that the beacon had been sabotaged by Klingon operatives to entrap the repair tender.[5] It is theorized that the Klingons gained technical information concerning robotics and repair techniques that they lacked, but it is not known just what gain this action brought them in the overall situation. Some analysts believed that study of the robotic repair systems could make it possible for Klingons to alter the functioning of navigation beacons robotically, creating potential havoc in border spacelanes.[3]
