The U.S. Navy told a website that releases formerly classified government documents that all Navy-held videos of unidentified aerial phenomena (UAP)—colloquially referred to as UFOs—are classified and are exempt from disclosure. The maritime service branch also stated that releasing them would “harm national security.”
The Black Vault is a privately run archive of declassified government documents obtained through Freedom of Information Act (FOIA) requests. The website features content mainly related to UFOs and similar phenomena.
