Discreet Oculus is an R&D effort to create a ground-based diagnostics system capable of providing accurate technical nuclear forensics conclusions following a nuclear detonation.
A more thorough description was sent out in a 2015 Defense Threat Reduction Agency (DTRA) press release:
“Discreet Oculus is a research and development effort to design and field a fully integrated, ground-based, geographically-dispersed, centrally-managed, operational prompt diagnostics system, and is designed to identify, and characterize a limited nuclear attack. Its sensors and computer networks record seismic, acoustic, air pressure, radiation, light, and radio frequency signals to help determine the size, location, altitude, and other characteristics of a nuclear attack. Information collected by this system will be used to help national and military leaders identify what was detonated, where the materials came from, and who launched or supported the attack.”
In May of 2018, The Black Vault filed a FOIA request to the DTRA for all records pertaining to Discreet Oculus. It would take more than 4 years, but the below packet of records was released in December of 2022.
They are available for download below.
