Given the fact that many of the Solrain ship designs include a 3 cubic meter shield generator bay, T&&P systems did not consider the market for an upscale shield of size 2 to be terribly important. However, market research found a niche that could be filled with minimal engineering expense. This resulted in the Cascade, a shield of size 3 that is not quite as powerful as the Alpaa, but which is also more moderately priced.
