The submarines had a surfaced displacement of 5580NaN0 and a submerged displacement of 7870NaN0. Propulsion while surfaced was provided by two diesel engines with a total of 1400hp and two electric motors with a total of 1000hp. The submarines' electrical propulsion allowed it to attain speeds of while submerged and on the surface. Their surfaced range was 4000nmi at 10kn with a submerged range of 82nmi at 5kn.^[1] ^[2] ^[3]
