text: # Hamul-class destroyer tender
  
  The Hamul class were a class of destroyer tenders that were initially constructed as attack cargo ships for the United States Navy during World War II. They operated from 1941 to 1969.
  
  ## Design and description
  
  Initially both ships were commercial cargo ships of the C3 type taken over by the United States Navy during World War II and converted to attack cargo ships. The ships measured 465 feet (142 m) long between perpendiculars and 492 ft 5 in (150.09 m) overall with a beam of 69 ft 8 in (21.23 m) and a draft of 28 ft 6 in (8.69 m). As attack cargo ships, they had a displacement of 11,755 long tons (11,944 t). After their conversion to destroyer tenders, they had a light displacement of 8,860 long tons (9,000 t) and measured 14,800 long tons (15,000 t) at full load. They were powered by steam generated from two Foster Wheeler boilers turning geared turbines creating 8,500 shaft horsepower (6,300 kW). This gave them a maximum speed of 18.4 knots (34.1 km/h; 21.2 mph). The ships were armed with a single 5-inch (127 mm)/38-caliber gun, four single-mounted 3 in (76 mm)/50 cal. guns and four 1.6 in (40 mm) guns. They had a complement of 857 officers and enlisted personnel.
