When submerged eachpropeller was driven by two 170-horsepower (127 kW)Electro-Dynamic Companyelectric motors. They could reach 14 kn (26 km/h; 16 mph) on the surface and 10.5 kn (19.4 km/h; 12.1 mph) underwater.[3] On the surface, the boats had a range of 2,300 nmi (4,300 km; 2,600 mi) at 11 kn (20 km/h; 13 mph) and 100 nmi (190 km; 120 mi) at 5 kn (9.3 km/h; 5.8 mph) submerged.[4]
The boats were armed with four18-inch (450 mm)torpedo tubes in the bow. They carried four reloads, for a total of eight torpedoes.[4]
