Marantha Calderon (Individual Concordat-class WarShip)
All of the Concordat-class frigates to be produced were launched before the end of the Reunification War. A number survived the War, despite the conquest of the various Periphery nations by the Star League Defense Force; seven of these vessels were still actively serving in either the Magistracy of Canopus or Taurian Concordat navies during the closing years of the Star League.
One of the seven Concordats still in service was the TCS Marantha Calderon; one of six Concordat-class frigates within the Taurian navy as at April 2765, the Marantha Calderon and two of her sister ships, the TCS Parilicium and TCS Parin, were deployed in support of II Corps of the Taurian Defense Force. II Corps was deployed on the border of the Federated Suns, and the Marantha Calderon and her sister ships had been assigned to assist the three active regiments of II Corps in deploying rapidly as needed. Each of the three ships was assigned in support of a particular regiment; the Marantha Calderon was supporting the Hyades Guards at the time.
