The USS Yosemite (NCC-19002) was a 24th century Federation Oberth-class starship operated by Starfleet. It had a total crew complement of only five science officers.

In 2369, the Yosemite was dispatched to the Igo sector to study a plasma streamer between two stars. During this mission, a plasma sample exploded in main engineering and the ship drifted off-course.

Subsequently, the USS Enterprise-D was sent to determine the Yosemite's fate. However, an away team found the vessel empty, save for the body of the chief engineer, Lieutenant Joshua Kelly, who died from exposure to high energy plasma. After Lt. Reginald Barclay, who was part of the Enterprise away team, claimed to see alien lifeforms while beaming between the two ships, it was found that he had been infected by quasi-energy microbes from the plasma streamer, which had also caused the explosion on the Yosemite. The remaining four Yosemite crewmembers were later discovered suspended in the transporter, and were rescued with the aid of Lt. Barclay. (TNG: "Realm of Fear")

Later that year, while under the mind control of interrogators on the planet Tilonus IV, Commander William T. Riker believed that he met a woman named "Commander Bloom," who was first officer of the Yorktown, at the Tilonus Institute for Mental Disorders. She told him that the Tilonians had captured a crewman from the Yosemite named Sanders. According to her, the doctors had done something to his mind. The commander believed that the doctors were removing neurochemicals from their brains, and she believed this was what happened to Sanders. (TNG: "Frame of Mind")

In 2370, the captain of this ship was J. Swift. After departing from New Brooklyn IX, the starship arrived at Deep Space 9 on stardate 47552.9. The Yosemite was listed on the space station's arrival roster. (DS9: "Whispers", production art)

...and its reference source

The Yosemite was named for the Yosemite National Park in North America according to the Star Trek Encyclopedia (4th ed., vol. 2, p. 510).

Yosemite's registry number could not be made out on-screen in the episode, but was featured on the cover of April 1993's Cinefantastique magazine, which was devoted to Star Trek: Deep Space Nine. Her registry number could be gleaned from that cover. The cover artist, David Voight, had an actual behind-the-scenes photograph of the studio model, dressed as the Yosemite, at his disposal as reference. The registry was confirmed one year later in the first edition of the Star Trek Encyclopedia (1st ed., p. 383).
