USS Armstrong

From Memory Alpha, the free Star Trek reference.

The USS Armstrong was a Federation starship in service during the late 24th century.

During the brief Federation-Klingon War (2372-73), the Armstrong was ambushed by Klingon forces in early 2373 and was severely damaged before escaping to Deep Space 9. (DS9: "Apocalypse Rising")

According to the Star Trek Encyclopedia, the ship was named after Neil Armstong who was the first man on the Moon on July 20th, 1969. The Encyclopedia also gives class and registry of this vessel as Challenger-class and NCC-57537, respectively.

According to the first two issues of the Malibu Comics Deep Space Nine comics, "Stowaway" and "Stowaway, Part II", the ship was an Oberth-class exploratory starship with a registry of NCC-19212 under Captain Johnson. Dr. Josiah Wembley, a renowned Federation xenobiologist was a member of her crew on their most recent mission to the Gamma Quadrant in mid-2369.
