She had a dive time of 32 seconds and was capable of operating at a depth of 50 metres (160 ft).
      The submarine's top submerged speed was 5.81 knots and its top surface speed was 9.15 knots (16.95 km/h; 10.53 mph). When submerged, she could operate for 45 nautical miles (83 km; 52 mi) at 5 knots (9.3 km/h; 5.8 mph); when surfaced she could travel 6,650 nautical miles (12,320 km; 7,650 mi) at 5 knots (9.3 km/h; 5.8 mph).
