description: America's most closely kept top-secret weapon of the cold war. Years after its retirement many technical aspects of this spyplane are still classified. It cruised at an amazing Mach 3 and its flying altitude was nearly 85000 feet. Its spy photos were critically important during the Cold War and vital during the Gulf War. A great value.
