Brunswick Executive Airport — Brunswick, United States

NHZ is Brunswick Executive Airport in Brunswick, Maine, built on the former Naval Air Station Brunswick, which the US Navy closed in 2011 as part of base realignment. Since the closure, the property has been redeveloped as a mixed-use aviation and business park called Brunswick Landing, with NHZ retained as a general aviation and executive airport. Its long runways, a legacy of the base's patrol aircraft operations, now support corporate jets, flight training, and occasional cargo or charter flights. The redevelopment has also brought technology and manufacturing tenants to the surrounding former base facilities. NHZ represents a notable example of successful military-to-civilian airport conversion in New England, retaining infrastructure originally built for maritime patrol squadrons.
