The CA-30 series cruiser-class starship is the Stellar Corps' workhorse capital-class starship. Designed and built by the Riyo Corporation, in early 22,109 GST, as a replacement for the aging CA-15 series, the CA-30 was the first Stellar Corps warship equipped with an STW Route transceiver system and Kelosian copies of Redeemptionist mass-reaction weapons, the original design acquitting itself well during the Congressional War.
