David Grusch

David Charles Grusch served 14 years as an intelligence officer in the US Air Force, reaching the rank of Major, and held senior positions at the National Reconnaissance Office and National Geospatial-Intelligence Agency. In 2022, he filed a whistleblower complaint with the Intelligence Community Inspector General that was deemed "credible and urgent," and in July 2023 he testified before Congress about his knowledge of alleged UAP crash retrieval and reverse-engineering programs. His account has become central to recent Congressional scrutiny of government UAP activities.

What positions did Grusch hold in government?

Grusch served as a Senior Intelligence Officer at the National Reconnaissance Office from 2016 to 2021, where he led production of the NRO director's daily briefing. From 2019 to 2021, he represented the NRO to the Unidentified Aerial Phenomena Task Force. He then worked at the National Geospatial-Intelligence Agency from 2021 to 2023 as a co-lead in UAP and trans-medium object analysis, reporting to the UAP Task Force and the All-Domain Anomaly Resolution Office. At the time of his testimony, he held the civilian rank of GS-15, equivalent to a full Colonel.

What did Grusch testify about in Congress?

During a July 26, 2023, House Oversight Committee hearing, Grusch testified that he "was informed in the course of my official duties of a multi-decade UAP crash retrieval and reverse-engineering program to which I was denied access." He stated that he believed the U.S. government was in possession of UAP based on interviews with 40 witnesses over four years. He also testified that the U.S. has recovered what he termed "non-human 'biologics'" from the crafts, and that this "was the assessment of people with direct knowledge on the [UAP] program I talked to, that are currently still on the program." Under oath, he repeated claims that the U.S. has likely been aware of "non-human" activity since the 1930s.

What is Grusch's basis for his claims?

Grusch stated that he has not personally seen any alien vehicles or alien bodies. Instead, his testimony is based on accounts from over 40 witnesses he interviewed during his work with the UAP task force. According to his testimony, these individuals have "a longstanding track record of legitimacy and service to this country," and many shared "compelling evidence in the form of photography, official documentation, and classified oral testimony."

What role did Grusch play in recent UAP legislation?

Grusch assisted in drafting the National Defense Authorization Act of 2023, which includes provisions for reporting of UAP, whistleblower protections, and exemptions to non-disclosure orders and agreements.

What happened after Grusch went public?

Grusch reported experiencing "very brutal" retaliation due to his allegations. In March 2025, Congressman Eric Burlison announced Grusch as a Special Advisor, recognizing his previous sworn testimony about federal government UAP activities and his expertise to contribute to transparency efforts regarding UAP.

How did the Pentagon respond?

The Pentagon's inquiries found no "verifiable information to substantiate claims that any programs regarding the possession or reverse-engineering of extraterrestrial materials have existed in the past or exist currently."
