SUBMARINES

UB III type medium submarines (1917-1918)

UB48 1917

Project history: War orders J (UB48-71), O (UB72-87), Q (UB88-132), T (UB133-169), W (UB170-205) and AB (UB206-249). These UB III type boats in fact constituted many different sub-groups, varying slightly in dimensions and machinery (MAN, AEG, Kortingor Benz). The design was essentially a reduced version of the Ms type, with a double hull and a diving depth of 50m. U176, 177, 184-195 and 206-249 were cancelled before their building started.
