The Z-class torpedo boats were a class of twelve warships that served in the Dutch Koninklijke Marine, German Kaiserliche Marine, Polish Marynarka Wojenna and British Royal Navy. The Royal Netherlands Navy ordered eight Z-class torpedo boats before the outbreak of World War I, four were to be built by the German shipbuilder AG Vulcan Stettin, to be named Z 1 to Z 4, while four others were to be built in the Netherlands; Z 5 to Z 8. After the outbreak of World War I the four ships under construction in Germany where requisitioned for service in the German navy, resulting in the Dutch Navy to order another four ships to be built in the Netherlands. The ships saw action during both World War I and World War II. One of the German ships was lost in World War I, while one Polish and one Dutch ship sank during World War II. Another Polish torpedo boat sank in peacetime due to a boiler explosion.^{[citation needed]}
