The U.S. Department of Defense releases a fourth batch of declassified UFO, or unidentified anomalous phenomena (UAP), files. Multiple outlets report the release happens on Friday and comes nearly one month after the prior (third) set of documents. The new tranche includes 40 additional records. Sources describe the contents as comprising 19 videos along with other materials such as documents, and in at least one account additional audio recordings and images. One report says the full set of materials draws from multiple U.S. agencies, listing the Pentagon alongside NASA, the CIA, the FBI, and the Department of Energy. Another outlet notes the package includes analysis tied to the video material, citing astrophysicist Avi Loeb. The releases are described as part of an ongoing effort by the Pentagon to publish previously withheld UAP-related materials in successive batches. Across coverage, the consistent details are the number of newly released items, the inclusion of 19 videos in the batch, and the continued pattern of periodic document drops.
