The US Navy has said that all UFO videos are classified and should not be published, writes Vice.

In response to a Freedom of Information Act request, the Pentagon told government transparency website The Black Vault that any public release of new UFO videos “will harm national security as it may provide adversaries valuable information regarding Department of Defense/Navy operations, vulnerabilities, and/or capabilities. No portions of the videos can be segregated for release.”

Black Vault searched for all videos tagged “unidentified flying objects”. Military departments typically issue what’s called a GLOMAR response, where they neither confirm nor deny that the records exist and refuse to say anything else. In this response, the military admit that they have more videos and justify the release of the three previous UFO videos.

“While three Unidentified Aerial Phenomena (UAP) videos were released in the past, the facts specific to those three videos are unique in that those videos were initially released via unofficial channels before official release,” said the message of the Pentagon. “Those events were discussed extensively in the public domain; in fact, major news outlets conducted specials on these events. Given the amount of information in the public domain regarding these encounters, it was possible to release the files without further damage to national security.”

The three videos which were leaked to former Blink-182 vocalist Tom DeLonge and the New York Times were not initially released by official sources. However, the Pentagon has spoken regularly about UFOs in recent years, and earlier this year it showed additional footage of unidentified objects to Congress. The military seem to want to tell the public and Congress that UFOs are very real and a threat, and that they need more funding to identify what they are and possibly protect us from them. But they are not going to show new videos about UFOs yet.
