The USS Ad Astra was a Federation starship serving during the early 24th century. It was of an unknown class but it apparently only carried a crew complement of a few dozen.
In 2311, Ad Astra, under the command of Captain Saren-Sah, joined the USS Enterprise-B and the USS Canaveral to escort the USS Universe during the trial run of its hyperwarp drive.
Ad Astra was severely damaged by the shockwave created by the explosion of Universe and Admiral John "Blackjack" Harriman, an observer on the bridge, was mortally wounded when thrown against a bulkhead. (ST - The Lost Era novel: Serpents Among the Ruins)
Elias Vaughn considered the incident on the Ad Astra a catastrophe. (DS9 - Mission Gamma novel: Twilight)
In 2372, the Ad Astra docked at Deep Space 9, where one of its younger officers enjoyed a game of dabo in Quark's. (DS9 novel: The 34th Rule)
- Ad Astra translates from Latin as "to the stars."
- All of the references to the Ad Astra were in novels by David R. George III.
