Flagship Valentina II

Its a Bespoke Built ship, designed from the ground up to be the Strongest Ship in the entire Navy, created to be able to take on an Entire fleet on Her own. 
The Ship started under the Project Insuperabilis , which also became its Ship Class officially later upon Completion. When Started, it was proposed as a Special Purpose Juggernaut for the SOL Defense Fleet and was accepted by the SOL Admiralty and Procurement. Solar Defense Works the Exclusive Arms Manufacturer for the SOL Fleet, had to work with Blackstar Shipyards , an Older Inner Core Company specialized in Titanic Transportation Ships and Logistics. Together with Darkstar they built a Special Shipyard for this ship around Altair, while SOL Works laid the Foundation for it's Building. 

Upon Completion, the Insuperabilis was sent to the Ares Ship Validation Center where it's abilities were very carefully recorded and eventually tested both in Simulation and in Real. When the Fleet was Presented their New Ship they were more than Satisfied and Humbly Requested Valentina II to be the Namesake, though it was expected to be rejected and so Insuperabilis, Darkstar, Earth, Tyr and a few others were suggested names but Much to the Surprise of the Admiralty they received the Allowance to use the name.
