David Grusch is a former U.S. Air Force intelligence officer and a former National Geospatial-Intelligence Agency (NGA) representative to the Department of Defense’s Unidentified Aerial Phenomena (UAP) Task Force. In 2023, he became a prominent public figure in the UAP debate after making whistleblower-style allegations about alleged secret programs and information being withheld from Congress.
Grusch’s claims were made in multiple settings, including interviews published by The Debrief and during a public hearing held by the U.S. House Oversight Committee’s Subcommittee on National Security, the Border, and Foreign Affairs on July 26, 2023. The hearing featured testimony from Grusch alongside former U.S. Navy pilots Ryan Graves and David Fravor.
It is important to separate allegations from verified facts. Grusch has publicly described what he says he was told and what he reported through government channels, but many of his most extraordinary assertions—such as recovered “non-human” materials or bodies—have not been substantiated with publicly released physical evidence.
Background
In 2020–2021, the Department of Defense and the U.S. intelligence community used “UAP” as a more neutral term than “UFO,” and oversight mechanisms expanded through the creation of the All-domain Anomaly Resolution Office (AARO). AARO’s mission includes investigating UAP reports and coordinating with other agencies.
Public interest increased after the release of several U.S. Navy videos and subsequent briefings, and Congress created new reporting requirements and whistleblower pathways related to UAP information. Grusch’s public allegations landed in this environment of heightened scrutiny and active legislative interest.
Key Claims Summarized
Grusch has alleged that elements within the U.S. government and defense/contractor ecosystem have operated compartmented UAP-related efforts without adequate congressional oversight. He has described these as involving the recovery and analysis of unusual craft, and he has used the phrase “non-human biologics” in connection with those allegations.
In public testimony, Grusch generally framed his knowledge as based on interviews and information provided to him by other officials, along with what he says he submitted to inspectors general and to congressional staff via protected disclosures. He has not publicly presented physical materials, detailed program documentation, or named program-specific evidence in an independently verifiable way.
What’s Verified vs. Alleged
Verified: A public congressional hearing occurred on July 26, 2023, and Grusch testified under oath; AARO exists and has issued official public reports; Congress has passed UAP-related reporting and oversight provisions in recent National Defense Authorization Acts.
Alleged: Claims of a long-running, covert crash-retrieval and reverse-engineering effort; allegations that information is being improperly withheld from Congress; claims of “non-human biologics.” These remain allegations in the public record unless and until corroborated by independently verifiable evidence, official confirmation, or credible documentary releases.
For official context, see AARO’s public reporting (AARO) and its historical review covering U.S. government investigations and allegations (AARO Historical Record Report, Volume 1 (2024)).
Terminology: UAP vs. UFO
“UFO” is the older, culturally loaded term, while “UAP” is the term used in many U.S. government documents to describe airborne (and sometimes multi-domain) objects or phenomena that cannot be immediately identified. The terms are often used interchangeably in popular discussion, but “UAP” is generally preferred in official settings to avoid assumptions about origin.

Who is David Grusch and what did he claim in 2023 about UAPs?
David Grusch is a former U.S. Air Force intelligence officer who worked in roles connected to UAP analysis and briefings. In 2023, he alleged that secretive U.S. programs existed outside normal congressional oversight and that these efforts involved the recovery and analysis of anomalous craft; he also used the phrase “non-human biologics” when describing what he said he had been told. He made these allegations publicly in interviews and under oath at a July 26, 2023 House Oversight subcommittee hearing (House Oversight hearing page).
-
What does “hidden U.S. UAP programs” mean in this context?
In this context, “hidden programs” refers to Grusch’s allegation that certain UAP-related activities were kept highly compartmented and not properly reported to Congress. He described this as a transparency and oversight problem rather than presenting publicly released documents proving the programs’ existence. Publicly available evidence has largely consisted of his sworn statements and reporting about his protected disclosures, not independently verifiable program records or physical materials released to the public.
-
Did David Grusch claim the U.S. recovered crashed UFOs?
Yes. In 2023 interviews and in congressional testimony, Grusch alleged that the U.S. government (and associated contractors) had recovered “craft” of unknown origin as part of a crash-retrieval and analysis effort. In public, he has generally described his knowledge as based on information provided by other officials and what he said he reported through inspector general and congressional channels; he has not publicly produced physical evidence, photographs, or documents that conclusively verify crash-retrieval claims. For broader official context on historical crash-retrieval allegations, see AARO’s public historical review (AARO Historical Record Report, Volume 1 (2024)).
-
What are “non-human biologics” in this context?
“Non-human biologics” is a phrase Grusch used publicly in 2023 when discussing what he alleged was associated with purported recovered craft. He did not publicly present biological samples, lab results, chain-of-custody documentation, or other independently verifiable evidence supporting this claim. As of publicly available reporting and official releases, the claim remains an allegation rather than a confirmed fact, and readers should treat it as unverified pending credible documentary disclosure, official confirmation, or independently corroborated evidence.
-
Is this story more about UFOs or UAPs, and why does it use both terms?
It is about the same topic using two different labels. “UAP” is the term most often used in U.S. government settings (including hearings and Pentagon offices like AARO), while “UFO” is widely used in public conversation and media. Using both terms reflects that the discussion spans official oversight and popular framing, especially when claims are debated in hearings and investigative reporting.
-
What should readers watch for next in credible UAP oversight and disclosure developments?
Watch for verifiable, document-backed updates rather than speculation: (1) additional public congressional hearings and the release of official transcripts and exhibits (House Oversight hearing materials); (2) Inspector General actions or public letters indicating what was investigated and what was substantiated; (3) new AARO reports and any accompanying declassified case data (AARO); (4) changes to UAP-related requirements in the National Defense Authorization Act and related reporting deadlines; and (5) high-quality investigative reporting that publishes primary-source documentation and on-the-record corroboration, such as the original 2023 reporting that introduced Grusch’s allegations to a broad audience (The Debrief (June 2023).
