Earth Alliance Olympus Class Corvette

The Olympus, first seen in early 2200 as a replacement for the smaller Laertes-class, served well for several decades until the Dilgar War, when logistical problems began to surface. The Alliance required an immense supply train into League territory, but keeping ammunition supplies available for both railguns and missile systems became a difficult challenge even with the Cotten Tenders and freighter support. It was an expensive, unwieldy and difficult ship to manage – but it was reliably so.

Olympus Corvettes were extremely uncomfortable vessels, not really suitable for long patrols or border defense due to unhappy crews and constant internal squabbles. In peacetime, they were generally treated as small monitors and left to guard bases or colonies just to give them somewhere to ‘stretch their legs’ when eventually necessary. In the aftermath of the Earth-Minbari War, many among EarthForce believed the Olympus was obsolete and needed to be replaced. It did not take long for the increased funding and shipbuilding influences to come up with a newer, less ammunition-hungry version which became much more popular among the navy.
