Project history

These UC III type minelayers were a considerable improvement on their predecessors, and had a diving depth of 75m. Two TT were sited amidships but were forward-firing. War orders S (UC80-118), V (UC119-152) and AC (UC153 and on). UC139-152 (KW Danzig) and UC153-192 were cancelled before were laid down.

Modernizations

None.

Naval service

UC90 was interned at Carlskrona (Sweden) 13.11.1918 and later transferred to Japan. UC91 sank in Baltic Sea after collision with s/s Alexandre Woermann 5.9.1918, salvaged next day, repaired and lost en route to transfer 10.2.1919 in the North Sea.
