This is Volume I of the Historical Record Report from the Department of Defense's All-domain Anomaly Resolution Office (AARO), dated February 2024 and released in full in February 2025. It reviews US government UAP investigations since 1945, from Project SIGN and Blue Book through the Condon Report, AATIP and the UAP Task Force. AARO found no evidence that any sighting involved extraterrestrial technology or that anyone reverse-engineered alien craft. It says the claims come largely from circular reporting, and it names KONA BLUE as a proposed program that was never approved.

SECTION I: Introduction
This report represents Volume I of the All-domain Anomaly Resolution Office’s
(AARO) Historical Record Report (HR2) which reviews the record of the United States
Government (USG) pertaining to unidentified anomalous phenomena (UAP). In completing this
report, AARO reviewed all official USG investigatory efforts since 1945, researched classified
and unclassified archives, conducted approximately 30 interviews, and partnered with
Intelligence Community (IC) and Department of Defense (DoD) officials responsible for
controlled and special access program oversight, respectively. AARO will publish Volume II in
accordance with the date established in Section 6802 of the National Defense Authorization Act
for Fiscal Year 2023 (FY23); Volume II will provide analysis of information acquired by AARO
after the date of the publication of Volume I.
Since 1945, the USG has funded and supported UAP investigations with the goal of
determining whether UAP represented a flight safety risk, technological leaps by competitor
nations, or evidence of off-world technology under intelligent control. These investigations were
managed and implemented by a range of experts, scientists, academics, military, and intelligence
officials under differing leaders—all of whom held their own perspectives that led them to
particular conclusions on the origins of UAP. However, they all had in common the belief that
UAP represented an unknown and, therefore, theoretically posed a potential threat of an
indeterminate nature.
AARO’s mission is similar to that of these earlier organizations. AARO methodology
applies both the scientific method and intelligence analysis tradecraft to identify and help
mitigate risks UAP may pose to domain safety and to discover, characterize, and attribute
potential competitor technological systems.
A consistent theme in popular culture involves a particularly persistent narrative that the
USG—or a secretive organization within it—recovered several off-world spacecraft and
extraterrestrial biological remains, that it operates a program or programs to reverse engineer the
recovered technology, and that it has conspired since the 1940s to keep this effort hidden from
the United States Congress and the American public.
AARO recognizes that many people sincerely hold versions of these beliefs which are
based on their perception of past experiences, the experiences of others whom they trust, or
media and online outlets they believe to be sources of credible and verifiable information. The
proliferation of television programs, books, movies, and the vast amount of internet and social
media content centered on UAP-related topics most likely has influenced the public conversation
on this topic, and reinforced these beliefs within some sections of the population.
The goal of this report is not to prove or disprove any particular belief set, but rather to
use a rigorous analytic and scientific approach to investigate past USG-sponsored UAP
investigation efforts and the claims made by interviewees that the USG and various contractors
have recovered and are hiding off-world technology and biological material. AARO has
approached this project with the widest possible aperture, thoroughly investigating these05Page determined to be Unclassified
