This is a model of a German F9C patrol boat, a small, fast vessel used by the German Navy (Kriegsmarine) during World War II for coastal patrols, scouting, and escorting larger ships. Designed for shallow waters, these boats helped protect coastal areas, assist in anti-submarine missions, and support bigger naval operations. While not as well-known as larger warships, their speed and versatility made them important for protecting and monitoring coastal and river areas during the war.
