The Heritage-class cutter, also known as the Offshore Patrol Cutter and the Maritime Security Cutter, Medium, is a cutter class of the United States Coast Guard (USCG), developed as part of the Integrated Deepwater System Program and built by Eastern Shipbuilding^[4] and Austal USA.^[5] Construction of the first vessel in the class began in January 2019. As they are completed, it is expected that they will replace 270-foot (82 m) Famous- and 210-foot (64 m) Reliance-class Medium Endurance Cutters.^[6]
