MV Asterix, also designated CSS Asterix, is a Canadian commercial container ship that was converted into a supply ship for the Royal Canadian Navy (RCN). It was purchased by Federal Fleet Services as part of Project Resolve and converted for use as an interim replacement between the out of service Protecteur-class replenishment oiler and the future Protecteur-class auxiliary vessel. Originally launched in Germany in 2010 as Cynthia, the ship was converted and delivered to the RCN in December 2017 and leased to the navy with a merchant navy crew, complemented by RCN personnel. Asterix will be in Canadian service well into the 2020s.
