The Project 482-class was a class of frigate built by the Ostri Republic, a prominent member of the Union of Independent Republics. Originally designed and built over a period of three years, starting in 22 B.E., the class grew rapidly, eventually reaching 485 vessels at the end of the first construction block. The class would serve with distinction during the last two decades of the Pendulum Wars, earning its place as a mainstay of the Navy. Even after the surrender of the UIR, the COG maintained and briefly attempted to expand the class, unfortunately, this was cancelled following Emergence Day, during which Ostri suffered massive casualties and damage to its infrastructure.
Roughly a year later, Chairman Richard Prescott announced the Hammer of Dawn Counterattack, a plan which called for all major population centers with heavy Locust infestations to be targeted by the Hammer of Dawn orbital weapon system. Ostri, having already lost almost two-thirds of its population fighting the Locust, panicked and many civilians and military personnel made their way to the few remaining naval bases, boarding ships like the Project 482-class en masse. When the Hammer dropped three days later, many assumed that the majority of the Ostrini people were killed in the attack, however, many thousands survived onboard ships, dozens of which made their way to the Jacinto Plateau. Others still, however, simply disappeared, preferring to live at sea rather than on land, where the Locust and a traitorous government waited.
