Quatre Belle was a core world within the Outworlds Alliance when Operation UNION HOLD began in 2581. After the Reunification war, the Quatre Belle's vast agricultural businesses became the provider of SLDF field rations and emergency relief kits for the region. In 3079 the Snow Ravens made Quatre Belle a production center for their aerospace assets. It wasn't clear in 3079 why they did this. During the Reunification War the SLDF established a naval repair yard in orbit around Pluto, Quatre Belle's third moon. Pluto contained large amounts of heavy metals, making it perfect for construction. The Quatre Belle Naval Yards were restored to operational status by the Snow Ravens, coming online in 3081 with the production of the CSR Mitchell Avellar. The Naval Yards represented one of just three shipyards in Clan-controlled areas of the Inner Sphere capable of producing ships, and gave the Snow Ravens the facilities to maintain and refurbish their WarShip fleet for the first time in some years.
