Wilk-class submarine

Wilk class submarines of the Polish Navy included three boats: ORP Wilk, ORP Ryś and ORP Żbik. They served from 1931 until 1955. The boats were built in France.

The class design was based on that of the French submarine Pierre Chailley, which had been laid down in 1917 and was in service from 1923 to 1936.
