The Hamilton-class cutter was the largest class of vessel in the United States Coast Guard until replaced by the Legend-class cutter, aside from the Polar-class icebreaker. The hull classification symbol is prefixed WHEC. The cutters are called the Hamilton class after their lead ship, or the "Secretary class" because most of the vessels in the class were named for former Secretaries of the Treasury, with the exception of the "Hero-class cutters" Jarvis, Munro and Midgett.
