The USCGC Dauntless (WMEC-624) is a United States Coast Guard cutter, commissioned in 1968 and still on active duty. She is the first cutter in Coast Guard history to hold this name. Like all ships in the Reliance class of 210-foot medium-endurance cutters, Dauntless is named for an aspirational trait, in this case meaning to "persevere fearlessly." This trait is further reflected in the ship's motto Sin Miedo which, in Spanish, means "Without Fear."
