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 icebreakers. The hull classification symbol is prefixed WHEC. The cutters are called the Hamilton class after their lead ship, or "Secretary class" because most of the vessels in the class were named for former Secretaries of the Treasury (with the exception of "Hero-class cutters" Jarvis, Munro and Midgett,).


They are powered by a Combined Diesel or Gas (CODOG) system consisting of two diesel engines and two gas turbines, and have controllable-pitch propellers. Equipped with a helicopter flight deck, retractable hangar, and the facilities to support helicopter deployment, these 12 cutters were introduced to the Coast Guard inventory in the 1960s.

History


Beginning in the 1980s and ending in 1992, the entire class was modernized through the Fleet Rehabilitation and Modernization (FRAM) program. The program included the replacement of the original Mk30 Mod0 5 in (127 mm)/38 caliber gun with a much more modern 76 mm (3 in)/62 caliber weapon. The refit also included the installation of a Phalanx CIWS 20 mm gun mount, and a retractable hangar bay. The primary mission of these vessels is enforcement of laws and treaties and search and rescue (SAR) on the high seas, including the U.S. exclusive economic zone.

AM broadcasting

"AM Radio" redirects here. For the song by Everclear, see AM Radio (song). For the American musical group, see AM Radio (band). AM broadcasting is a radio broadcasting technology, which employs amplitude modulation (AM) transmissions. It was the first method developed for making audio radio transmissions, and is still used worldwide, primarily for medium wave (also known as "AM band") transmissions, but also on the longwave and shortwave radio bands. The earliest experimental AM transmissions were begun in the early 1900s. However, widespread AM broadcasting was not established until the 1920s, following the development of vacuum tube receivers and transmitters. AM radio remained the dominant method of broadcasting for the next 30 years, a period called the "Golden Age of Radio", until television broadcasting became widespread in the 1950s and received most of the programming previously carried by radio. Subsequently, AM radio's audiences have a...
