This submarine was built in Russia by Mikhail Puchkov and its first floating nearly ended in getting its owner into the prison. But instead of sending him to prison they sent him to ship building institute after seeing his ship building talent.
The length of submarine is only meter, but in the above-water position boat can cover a distance, let us say, from Petersburg to Helsinki and vice versa.
