The Aquacade satellite program was known by the designations SIGAD AFP-720 and SIGAD AFP-472.
Notes on verification
Multiple independent, specialized sources (GlobalSecurity.org, Astronautix.com, Gunter's Space Page) consistently confirm both SIGAD designations AFP-720 and AFP-472 for the Aquacade/Rhyolite program. These are authoritative aerospace/military history references that corroborate each other on specific program designations.
