The Odyssey class was a type starship introduced by the Federation Starfleet in the early 25th century. Designated as an explorer or star cruiser type vessel, the class had several configurations which focused on either tactical, science or operations functions.
Like the older Galaxy-class, the Odyssey class was able to separate its primary hull from secondary hull, providing the stardrive section with greater maneuverability once the chevron was away. The Odyssey class was also equipped with quantum slipstream drive. (Star Trek Online)
