Sky Three
The Sky Three represented a civilian engine design. North River Industries began its production run in 900 BBY. This engine was conceived as a versatile model, made to be compatible with a wide array of starships. Despite certain shortcomings, its affordability, simple manufacturing, and respectable performance made it popular. Consequently, it became the most prevalent starship engine within the Aakaash system. More than 50% of the Silver Knights' starships were powered by this particular engine. Furthermore, the Sky Three served as the foundation for numerous other engine designs, and its interchangeable parts allowed for modifications, such as transforming it into variants within the Open Sky series.
