Project history

Submarine minelayers, built under original project, ordered 12.12.1934. Part of amount on building has been obtained from sale of two destroyers to Peru and a part was collected on a subscription among the population.     Submarines had saddle-tank construction with side bulges in which ballast tanks and the mine tubes took places. Light hull on waterline was strengthened for ice navigation. Mines were carried on two in 10 vertical tubes (on 5 aside). The 40mm MG in submerged position was retracted into watertight trunk. TTs had special brasses for usage of 450mm of torpedoes. As a whole submarines differed by good performance parameters, from lacks the shallow diving depth was marked.
