Heroj-class submarine

The Heroj class was a class of diesel-electric attack submarines built for the Yugoslav Navy during the 1960s. The three strong class was the second generation of domestically built submarines, representing a significant improvement compared to the earlier Sutjeska class. Built at the Brodogradilište specijalnih objekata in Split, the new class featured a streamlined hull design and four bow facing torpedo tubes that could also be used for minelaying.
