The centerpiece of the memorial is a C-130 aircraft, refurbished to resemble the reconnaissance-configured C-130A which was downed by Soviet fighters over Armenia on 2 September 1958. In addition to the C-130, the NVP also has on exhibit an Army RU-8D Seminole. This aircraft pays tribute to the service and sacrifice of soldiers assigned to perform aerial reconnaissance and cryptologic intelligence-gathering missions during the Vietnam Conflict. The aircraft was completely restored and donated by the Transportation Museum, Fort Eustis, Virginia, to the 704th Military Intelligence Brigade.
Finally, the U.S. Navy's contribution to National Vigilance Park bears the markings of an EA-3B aircraft, Ranger 12, assigned to Fleet Air Reconnaissance Squadron Two (VQ-2). The original aircraft was lost during an operational mission in the Mediterranean on 25 January 1987 while attempting a landing on the USS Nimitz. All seven crewmembers aboard Ranger 12 perished.
Aerial reconnaissance became necessary in the 1940s and 1950s because of the Cold War. Soviet propaganda boasted of its strong defense capabilities, and its record of achievement in World War II added credibility to these claims. The USSR detonated its first atomic weapon in 1949, years ahead of American estimates. In the 1950s, Soviet advances in rocket science increased the possibility that the continental United States could become a nuclear battleground. Washington's (incorrect) assumption that the Soviets had prompted the Korean War led policymakers to the conclusion that the Soviets were ready for a hot war.
