Newport-class tank landing ships were an improved class of tank landing ship (LST) designed for and employed by the United States Navy from 1969 to 2002. The ships were intended to provide substantial advantages over their World War II-era predecessors. Larger and faster than any previous LST design, they carried a ramp over the bow that allowed them to surpass 20 knots, a goal of the United States amphibious forces. 27 were planned of which twenty were completed, the high number due to the demands of US force projection estimates. However, the arrival of the air-cushioned landing craft which allowed for over-the-horizon attacks made the class obsolete in the eyes of the United States Navy. Placed in reserve, twelve were eventually sold to foreign navies, while the remaining eight have since been decommissioned.

Landing Ship, Tank (LST), or tank landing ship, is the naval designation for ships first developed during World War II (1939–1945) to support amphibious operations by carrying tanks, vehicles, cargo, and landing troops directly onto a low slope beach with no docks or piers. The shallow draft and bow doors and ramps enabled amphibious assaults on almost any beach.
