The USS Al-Batani was a 24th century Federation starship operated by Starfleet.
Captain Owen Paris was the commanding officer of this ship. This was the first posting of Kathryn Janeway. (VOY: "Caretaker", "Shattered")
While under the command of Captain Paris, the Al-Batani participated in the Arias Expedition, with Janeway serving as the ship's science officer. (VOY: "Caretaker", "Live Fast and Prosper")
One memorable incident aboard the Al-Batani was when Janeway accidentally disabled power to six decks after misaligning the ship's positronic relays. (VOY: "Shattered")
During one of the missions aboard the Al-Batani, the ship became trapped for three days by intense gravimetric forces inside a proto-nebula. (VOY: "Bride of Chaotica!")
According to the Star Trek Encyclopedia (3rd ed. p.470), this starship was an Excelsior-class vessel; its registry number was stated to have been NCC-42995.
The Al-Batani appeared to have been named after the 9th and 10th-century Arab prince and astronomer of the same name.
