Both the RRW Craeul and the IKS baSro' were based on the USS Altair design, which entered production as the Cestus-class frigate. These classes entered service alongside their motherships in the 26th century, at some point before the Battle of Procyon V. Around 2769, the Craeul detached from the RRW Valkis to cruiser the orbit of New Khitomer. (STO mission: "Reckoning", STO website: 26 Century Dreadnought Stats!)
