Submarines of this type have an underwater displacement of about 1600 tons with a length of 60,4 meter and a width of 6,2 meter. Immersion depth - 320 meters. Speed under water - 20 nodes. Crew - 27 man. Armament: Torpedo-mine - 4 nasal 533-mm TA, 12 torpedoes; 2 nasal 400-mm TA, 6 torpedoes; 12 min (instead of torpedoes). Initially, these submarines were equipped with a Stirling engine, which makes it possible to extend the stay of the submarine under water for up to two weeks instead of the usual several days.
In the course of the modernization, a third-generation Stirling engine, modern detection tools and a new control system developed for the next-generation A26 submarines were installed on the Gotland.
