National Vigilance Park, Military memorial park in Fort Meade, Maryland, United States.
National Vigilance Park is a memorial site on the grounds of the National Security Agency in Fort Meade, Maryland, where three historic reconnaissance aircraft are displayed outdoors. The planes come from different branches of the military and stand alongside a row of trees planted across the grounds.
The park was established in 1997 to honor the crews who lost their lives during reconnaissance flights in the Cold War era, following events such as the shooting down of an American aircraft over Armenia in 1958. That incident became one of the most dangerous moments in the history of military intelligence gathering.
The park honors the crews of reconnaissance aircraft who flew dangerous secret missions during the Cold War, with real planes on display and trees planted as markers. Each tree represents a mission where lives were lost, making the human cost visible in a direct and tangible way.
The park sits on a military base and requires authorization to enter, so a visit cannot be made without prior arrangements. Plans exist to relocate it next to the National Cryptologic Museum, which is open to the general public.
One of the aircraft on display is a reconstruction built from a 1957 plane to match the exact type that was shot down in 1958. This was done because almost nothing remained of the original aircraft after it went down.
