Racehorse displaced 1,705 long tons (1,732 t) at standard load and 2,425 long tons (2,464 t) at deep load. She had an overall length of 358 feet 3 inches (109.2 m), a beam of 33 feet 8 inches (10.3 m) and a deep draught of 13 feet 6 inches (4.1 m). She was powered by two Parsons geared steam turbines, each driving one propeller shaft, using steam provided by two Admiralty three-drum boilers. The turbines developed a total of 40,000 shaft horsepower (30,000 kW) and gave a maximum speed of 36 knots (67 km/h; 41 mph). Racehorse carried a maximum of 470 long tons (480 t) of fuel oil that gave her a range of 4,675 nautical miles (8,658 km; 5,380 mi) at 20 knots (37 km/h; 23 mph). Her complement was 176 officers and ratings.
The ship was armed with four 45-calibre 4.7-inch (120 mm) Mark IX guns in single mounts. For anti-aircraft (AA) defence, Racehorse had one quadruple mount for QF 2-pdr Mark VIII ("pom-pom") guns and six single 20-millimetre (0.8 in) Oerlikon autocannon. She was fitted with two above-water quadruple mounts for 21-inch (533 mm) torpedoes. Two depth charge rails and four throwers were fitted for which 70 depth charges were provided.
