The SK Leitstrahl-Gerätesatz und Unterstand is a World War II German military bunker located in Dunkirk, France. As part of the Atlantic Wall fortifications, this structure served as a command post for the Stützpunkt Artillerie Gruppe Dunkirchen (F-15B). The bunker was designed for the direction and observation of coastal artillery batteries, playing a crucial role in the German defensive strategy along the French coastline.
Its partially integrated position within the current urban landscape of Dunkirk reflects the lasting impact of wartime infrastructure on the city's geography.
