NCC 642 was used to familiarise the cadets with actual operations in space. The use of an Oberth class scout class vessel allowed the 80 cadets and trainers to travel the solar system, and slightly beyond, and practice their area of study in a real environment. The Ballard was a dedicated science vessel with limited defensive capabilities and limited cargo space. The cadets were berthed in communal dormitories to appreciate that in this, the most common starship class in starfleet, the accomodation was anything but spacious.

Construction of the Oberth class began in earnest after the first vessel, NCC 602 U.S.S. Oberth, was commissioned in 2275 - based on the fandom date for the commissioning of the first Gagarin/Oberth class vessel. Oberth class construction will continue until the replacement design, Nova class, begins construction in 2368. Indeed when seen in Star Trek: Generations, rescuing the surviving crew of the U.S.S. Enterprise-D from the surface of Veridian III [supporting Nebula class U.S.S. Farragut and Miranda class U.S.S. Bozeman] the U.S.S. Valiant NCC 20000 was completing her final mission, to be replaced shortly thereafter by NCC 74210, U.S.S. Valiant - Defiant class.
