Project history

First submarines, designed in Germany after the First World War. Order for 2 ships was given out 17.12.1934, long before official denunciation of Versailles Peace Treaty. By construction they practically completely repeated E1, built for Spain, but later sold to Turkey as Gür. Saddle-tank type, maximal diving depth was 150m. Instead of torpedoes they could carry accept 28 TMA or 42 TMB mines. Submarines were considered unsuccessful because of bad seaworthy and manoeuvring capabilities, and also an endurance not too differing from medium submarines of VII series.

Modernizations

None.

Naval service

U25 was lost, presumably, 1.8.1940 N off Terschelling on the mines laid by British destroyers Esk, Express, Icarus and Impulsive. U26 was sunk 1.7.1940 by British corvette Gladiolus and Sunderland of 10th RAAF sqn SW off Ireland.
