AATIP (Advanced Aerospace Threat Identification Program)

The Advanced Aerospace Threat Identification Program (AATIP) was a small, unpublicized Pentagon effort that examined reports of unidentified aerial phenomena in the 2000s and 2010s. Its public exposure in December 2017 is the single event that restarted official U.S. government engagement with UAP. Every current program, from AARO to the PURSUE records releases, traces its lineage to that story.

The effort began as the Advanced Aerospace Weapon System Applications Program (AAWSAP), funded at the request of Senate Majority Leader Harry Reid of Nevada with support from Senators Ted Stevens and Daniel Inouye. The Defense Intelligence Agency awarded the roughly $22 million contract in 2008 to Bigelow Aerospace Advanced Space Studies (BAASS), a company owned by Reid's constituent Robert Bigelow. AAWSAP produced dozens of technical reference papers and investigated reports of anomalous activity, including at Skinwalker Ranch in Utah. Program funding ran through about 2010, and the Pentagon says the effort formally ended in 2012.

AATIP is the name most associated with the effort's UAP casework, including review of military pilot encounters like the 2004 Nimitz incident and the 2015 East Coast videos. Intelligence official Luis Elizondo says he ran AATIP from 2010 until his resignation in October 2017, when he left in protest of internal secrecy. He then joined To The Stars Academy, the private venture that helped bring the Navy videos to the press.

On December 16, 2017, The New York Times revealed the program's existence in a story by Helene Cooper, Ralph Blumenthal, and Leslie Kean, published alongside two Navy UAP videos. Politico published a parallel report the same day.

Defunct. Its successors are a chain of official programs: the Navy-led UAP Task Force (2020), the Airborne Object Identification and Management Synchronization Group (2021), and the All-domain Anomaly Resolution Office (AARO), established in July 2022 and directed since August 2024 by Dr. Jon Kosloski. In 2026 the Department of War began publishing declassified UAP records at war.gov/UFO under the PURSUE initiative.

The Pentagon has given inconsistent accounts of AATIP. It confirmed the program existed but at one point stated Elizondo had no assigned role in it, a claim he and several officials disputed. The scope of what AATIP actually produced remains contested. The funding, the contract, the reference papers, and the program's role in bringing the Navy videos to light are documented. Assertions that the effort recovered or studied exotic materials have not been verified publicly, and AARO's 2024 Historical Record Report stated it found no evidence of any reverse engineering program. Whatever AATIP was, UAP reporting is now a formal, funded government function, and that chain of programs began here.
