ARA San Martín was one of four Giuseppe Garibaldi-class armored cruisers purchased by the Argentine Navy from Italy.

San Martín had an overall length of 344 feet 2 inches (104.9 m), a beam of 50 feet 8 inches (15.4 m), and a mean draft (ship) of 23 feet 4 inches (7.1 m). She displaced 6,773 metric tons (6,666 long tons) at normal load. The ship was powered by two vertical triple-expansion steam engines, each driving one shaft, using steam from eight Scotch marine boilers. The engines were designed for a maximum output of 13,500 indicated horsepower (10,100 kW) and a speed of 20 knots (37 km/h; 23 mph). She had a cruising range of 6,000 nautical miles (11,000 km; 6,900 mi) at 10 knots (19 km/h; 12 mph). Her complement consisted of 28 officers and 460 enlisted men.

Her main armament consisted of four 45-caliber Armstrong Whitworth 8-inch (203 mm) guns, in twin-gun turrets fore and aft of the superstructure. The ten 40-caliber quick-firing (QF) 6-inch (152 mm) guns that comprised her secondary armament were arranged in casemates amidships on the main deck. San Martín also had six QF 4.7-inch (119 mm) and six QF 6-pounder Hotchkiss guns to defend herself against torpedo boats. She was also equipped with four above-water 457 mm (18.0 in) torpedo tubes, two on each side.
