Project history: Former Italian MTBs of MS type 3rd series, built by CRDA on the sample of the Yugoslavian boats. In September, 1943 they were captured (Only MS75 and MS76 were completed that time) and included to German fleet list. MS75 and 76 were initially transferred to RSI but reverted in 1944 to German navy.

Modernizations: None.
