The Mercury-Class Frigate is a vessel designed by the Triumvirate to focus on the newly developed Thor's Hammer technology, an improvement on the MARC technology, and to build with new sweeping low profile hull designs developed by a unified Triumvirate. Designed and crafted as part of the Triumvirate's Onyx Project, these vessels are the foremost in speed and stealth thanks to their low profile and new systems. Compared to traditional warships the Mercury-Class appears more like that of a civilian craft, with a secured interior and reinforced transparasteel viewports the Mercury-class is a complete warship.
