She had a total length of 65.80 m (215 ft 11 in ), a pressure hull length of 50.07 m (164 ft 3 in ), a beam of 6.20 m (20 ft 4 in ), a height of 9.35 m (30 ft 8 in ), and a draught of 3.88 m (12 ft 9 in ). The submarine was powered by two 2,400 metric horsepower (1,800 kW; 2,400 shp) engines for use while surfaced, and two 1,200 metric horsepower (880 kW; 1,200 shp) engines for use while submerged. She had two propeller shafts. She was capable of operating at depths of up to 50 metres (160 ft ).
The submarine had a maximum surface speed of 15.6 knots (28.9 km/h; 18.0 mph) and a maximum submerged speed of 8.6 knots (15.9 km/h; 9.9 mph). When submerged, she could operate for 56 nautical miles (104 km; 64 mi ) at 5 knots (9.3 km/h; 5.8 mph); when surfaced, she could travel 11,380 nautical miles (21,080 km; 13,100 mi ) at 8 knots (15 km/h; 9.2 mph).
