Rhyolite/Aquacade
From Wikipedia, the free encyclopedia
Rhyolite and later, Aquacade are reportedly code names for a class of SIGINT reconnaissance satellites operated by the National Reconnaissance Office for the United States Central Intelligence Agency. The program, also known as AFP-720 and AFP-472[1], remains classified.
It is believed that at least four Rhyolite/Aquacade satellites were launched from Cape Canaveral between June 1970 and April 1978 on Atlas/Agena D launch vehicles. The satellites weigh approximately 700 kg and operated in near-geosynchronous orbits over the Middle East.
The name of the program, originally "Rhyolite", was changed to "Aquacade" in 1975 following the disclosure of the codeword "Rhyolite" in the trial of Christopher Boyce and Andrew Lee.
The Rhyolite/Aquacade satellites, made by TRW, are rumored to have an umbrella-like reflecting dish 20 meters in diameter. They were succeeded by the Magnum/Orion and Mentor (satellite) series of satellites.
