Discovery (NX-03) was a United Earth NX-class starship that was stuck on a subspace sandbar and presumed lost until it was recovered by the USS Baldwin in 2377. Discovery was launched on June 24, 2156, upon the onset of the Earth-Romulan War, and its first mission was to engage the Romulans. Six months after launch, the ship was swept by a subspace current into the subspace sandbar in the Beta Quadrant. Upon realizing the futility of escaping the sandbar, the captain set the ship up to be a generational outpost of humanity. By 2377, Kyle Galesburg was in command of Discovery.
