Incident Overview
This report was produced by Bigelow Aerospace Advanced Space Studies (BAASS), the Las Vegas contractor that ran the Defense Intelligence Agency’s Advanced Aerospace Weapon System Applications Program (AAWSAP), and is dated April 2010. It was declassified and published on October 23, 2026 as part of the seventh tranche of the Department of War’s Presidential Unsealing and Reporting System for UAP Encounters (PURSUE). The released copy carries redactions.
What the government released
This document is an administrative, programmatic, or contractor-produced record related to the Advanced Aerospace Weapon System Applications Program (AAWSAP), a Defense Intelligence Agency (DIA)-administered program active from 2008 to 2012. AAWSAP’s official scope of work identified 12 technical research areas relating to potential aerospace threats over a time horizon of more than 40 years. As part of the broader program record, the file documents how AAWSAP was scoped, organized, tasked, funded, executed, or described at a particular point in time.
This April 2010 Bigelow Aerospace Advanced Space Studies (BAASS) investigation report documents field deployments to a Utah property and surrounding communities during March and April 2010. The report states that BAASS personnel interviewed local residents, law enforcement officers, ranchers, business owners, and tribal community members about reported anomalous events; used handheld sensors to collect environmental measurements; planned plant-based biosensor experiments; and sought photographic, acoustic, and chemical evidence of purported anomalous phenomena. It also records extensive reported accounts involving “dog-like bipedal creatures,” orbs of light, “little people,” “prehistoric-looking” birds, among other phenomena, and states that BAASS intended to use interactive methods to attempt communication with the presumed source of reported anomalous activity.
The case in this archive
This record is a primary source for the Advanced Aerospace Weapon System Applications Program and Skinwalker Ranch, written up here at length from the contemporary record. The file and the case history are worth reading against each other: the document is narrower and more cautious than the account that grew up around it, which is usually the point.
Status of the case
This is a contractor’s report to the government, written by a firm that was paid to study the subject and had its own reasons to show that the work was worth continuing. Its statements are the contractor’s claims, not Defense Intelligence Agency findings, and the Department of War’s release carries no endorsement of them. Where the report relays witness accounts, many of them taken from the Mutual UFO Network’s case files, those accounts were not independently checked in any way the pages show. Its value is as a record of what the program actually did month to month, which is the question public argument about AAWSAP has most lacked documents to answer. The All-domain Anomaly Resolution Office has made no determination about this record.
