The Captain Sulu Adventures, released in 1994 and 1995, is a series of audiobooks centred around the USS Excelsior under the command of Hikaru Sulu. Unlike most other Star Trek audiobooks, the three releases in the series were original full-cast audio drama productions featuring George Takei, rather than readings or adaptations of previously published novels. Although Simon and Schuster would later release a version of the soundtrack to the computer game Borg reformatted into an audio drama, as of 2019 the Captain Sulu Adventures stand as the only official attempt at producing an ongoing original audio drama series based upon the franchise.
