Naval Air Station Joint Reserve Base Willow Grove, U.S. Navy airbase
Naval Air Station Joint Reserve Base Willow Grove is a former military airfield in Horsham Township, Pennsylvania, that once covered approximately 1100 acres and housed various military branches. The site still displays remnants of old runways, hangars, and military structures from its operational years.
The facility began in 1926 as a private airfield established by aviation pioneer Harold F. Pitcairn and was taken over by the U.S. Navy in 1942, officially named in 1943. After World War II it served as a training and reserve base until its closure in 2011.
The site takes its name from the nearby town of Willow Grove and served for many decades as a center for aviation innovation and military training. The local community maintains a connection to this heritage through veterans and residents who remember the aircraft and activity that were part of daily life for generations.
The site is easily accessible via County Line and Easton Roads and offers open spaces to explore. Visitors should note that parts of the property remain under maintenance and environmental cleanup, so it is wise to check access conditions beforehand.
The site was home to an annual air show that drew aviation enthusiasts until it ended in 2006, and was the origin point of an unexpected helicopter landing on the White House lawn during the base's operational years. These events are part of the local lore and demonstrate how this military installation was woven into national incidents.
