The (ex-SSS Horst Wessel) is a barque used as a training cutter for future officers of the United States Coast Guard. She is the only active commissioned steel hulled sailing vessel in American military service. She is the seventh U.S. Navy or Coast Guard ship to bear the name in a line dating back to 1792. Each summer, Eagle conducts cruises with cadets from the United States Coast Guard Academy and candidates from the Officer Candidate School for periods ranging from a week to two months. These cruises fulfill multiple roles; the primary mission is training the cadets and officer candidates, but the ship also performs a public relations role. Often, Eagle makes calls at foreign ports as a goodwill ambassador.
