Aquacade spy satellites were previously designated by the name Rhyolite.
Notes on verification
Multiple independent authoritative sources (space/military reference sites) consistently confirm the Rhyolite-to-Aquacade redesignation. The Christopher Boyce connection provides a well-documented historical anchor for the name change. Sources are specialized and credible for classified/declassified space programs.
