Forintos Gyula's first submarine, SS86H, was extensively demonstrated to the Hungarian military for river use in the early 1990s, particularly for mine clearance. That proposition is a serious one as the Danube has been mined repeatedly in WWI and WWII and unexploded mines remains a threat. The Hungarian Defense Forces did not purchase the sub.
