Sea-Airport Cuxhaven/Nordholz is a dual-use facility located near Wurster Nordseeküste in Lower Saxony, Germany. It serves both as a German Navy (Deutsche Marine) base — known as Marinefliegergesellschaft Nordholz — and as a small civilian regional airport under the IATA code FCN. The naval component, designated ETMN under ICAO, hosts German naval aviation assets including maritime patrol and helicopter operations. Civilian traffic has historically been limited, with seasonal and charter services connecting the region to North Sea island destinations. The airport sits close to the Cuxhaven coast and has been explored as a gateway for tourism in the Wadden Sea region, though scheduled commercial services have been sparse and inconsistent over the years.
