Ship project history: Submarines of smaller, in comparison with the predecessors, displacement. The decision on their building is accepted right after the Second World War beginnings. First of all they were intended for coast defence in case of landing of one of belligerent parties. Their construction was whenever possible simplified for acceleration and reduction in price of building. Unique Swedish single-hulled submarines (others were double-hulled). The so-called "American" machinery scheme became other difference of these submarines: diesel worked on the generator which, in turn, charged battery or gave a current on two main electric motors.

Modernizations: 1950s, all: - 1 x 1 - 20/66, 1 - 533 TT (stern); CT was streamlined (submerged speed increased to 9kts)

Naval service: no significant events.
