Sava-class submarine

The Sava class was a class of diesel-electric attack submarines built for the Yugoslav Navy during the late 1970s and early 1980s. Developed by the Brodarski Institute (BI) from Zagreb, the two strong class was built by the Brodogradilište specijalnih objekata in Split. They were intended as a replacement for the aging Sutjeska-class submarines. Compared to the earlier Heroj class, the Sava class was longer with more powerful armament that consisted of six torpedo tubes that could also be used for minelaying.
