A Sensitive Compartmented Information Facility (SCIF) is a secure space used to store, discuss, and view Sensitive Compartmented Information (SCI) belonging to a Special Access Program (SAP). A SAP designation is not itself a higher security classification than top secret; it denotes that a project is compartmented, its material designated SCI, and given a codename.1 Even the most senior military officials holding the highest top-secret clearance are barred from the details behind a SAP or SCI codename unless they have been formally “read into” the programme.2 A SCIF is built to block sound, radio, and electromagnetic waves.3 Christopher K. Mellon’s role on the staff of the US Senate Select Committee on Intelligence required him to review top-secret SCI projects held inside SAPs, most of which remain classified.4 John Podesta held top-secret/SCI clearances in his earlier roles under Presidents Barack Obama and William J. Clinton.5 According to In Plain Sight, sources with top-secret and compartmented security clearances say that no senior military official holding a Top Secret Sensitive Compartmented Information (TS-SCI) clearance should ever be surprised at being refused information by a contractor.6
SCIFs feature repeatedly in first-hand accounts of Pentagon-based programmes investigating Unidentified Anomalous Phenomena (UAP) given by Luis Elizondo. Jay Stratton and James Lacatski briefed Elizondo on the Advanced Aerospace Weapon System Applications Program (AAWSAP) and the Advanced Aerospace Threat Identification Program (AATIP) inside a SCIF.7
Harold E. Puthoff visited the Pentagon and met Elizondo’s team in a SCIF.8 Elizondo and Puthoff went on to discuss propulsion theories for UAP in a SCIF for several hours.9 Elizondo has said that during that discussion the group identified a possible explanation for elevated UAP activity around nuclear sites and technologies.10
Elizondo also used a SCIF to share reports, photographs, data, and intelligence on legacy UAP efforts with Mellon over the course of three hours.11 Mellon had earlier visited Elizondo’s SCIF unannounced, identifying himself and expressing interest in helping AATIP.12
SCIF spaces also hosted the weekly meetings held under OPLAN Interloper, for which the National Security Agency (NSA) and Central Intelligence Agency (CIA) offered assets in support; some of these meetings took place at the Pentagon and others at different agencies.13
Elizondo envisioned an alternative to routine SCIF access, proposing to declassify some UAP videos and make them available to handpicked colleagues in the defence industry via a secure government server, rather than requiring them to obtain clearance and view the footage in a SCIF.14 In 2023, Elizondo made multiple trips from his home to Washington DC and spent many hours in a SCIF with US Senate leaders regarding the UAP Disclosure Act.15
