The United States National Vigilance Park (NVP) was a memorial to the military servicemen who participated in aerial reconnaissance during the Cold War.

Dedicated on September 2, 1997, NVP was located just one block from the National Security Agency (NSA) headquarters at Fort George G. Meade, Maryland.

Military events connected with the Intelligence Community and/or personnel stationed at Ft. Meade or working at NSA were formerly scheduled through the National Cryptologic Museum (NCM), which is just one block west of the former park.

Photographing the planes and the memorial plaques, decor, and grounds was allowed when they were on site; however, pictures of the adjacent NSA buildings were not permitted due to security concerns.

A Hercules C-130 transport, tail number 60528, modified to look like a reconnaissance-configuration C-130A, memorialized a U.S. Air Force aircraft shot down over Soviet Armenia during the Cold War.
