At the time of the Xindi attack on Earth in 2153, the second NX Class starship, the Columbia, was still under construction. In November 2154, the Columbia was launched under the command of Captain Erika Hernandez. (ENT: "Affliction")

Compared to the class prototype, Enterprise, Columbia's hull polarization was improved by 12%. Furthermore, she possessed ventral and dorsal photonic torpedo launchers as well as pulsed phase cannons. Another improvement was that the bridge stations were directly tied into the primary EPS junction. (ENT: "Home")

In November of 2154, the Columbia was stuck in dry dock with engine trouble, delaying her launch, and rendering her unable to assist the Enterprise during the hunt for the Romulan drone-ship. (ENT: "United")

In late 2154, the vessel's engine troubles were fixed upon the transfer of Enterprise engineer Charles Tucker to the Columbia, allowing the vessel to be launched in November of that year. (ENT: "Affliction")
