USCGC Reliance (WMEC-615)

1963  The first of the new class of 210-foot cutters, CGC Reliance (WPC-615, later WMEC-615), was christened at Todd Shipyard, Houston, Texas.  The wife of the Commandant at the time, Mrs. Edwin J. Roland, was the sponsor for the cutter.  A news report published at the time noted: “The CGC RELIANCE, to be stationed at Corpus Christi, Texas, marks a significant milestone in the building program of the Coast Guard as it is the first cruising cutter of any size built for Coast Guard service in almost twenty years.”
