The Osetr class were a group of submarines built for the Imperial Russian Navy during the Russo Japanese War. The boats were ordered in the 1904 emergency programme. The boats were designed by American Engineer Simon Lake and had wheels fitted for moving around on the sea bed as well as wet/dry chambers for divers. The Osetr was the former Protector sold by Lake to the Russians and re-assembeld in Russia. The diving depth was 16 fathoms.
