The AARO Historical Record Report is a review by the Pentagon's All-domain Anomaly Resolution Office (AARO) of the U.S. government's involvement with unidentified anomalous phenomena (UAP) since 1945. Volume 1, released on 8 March 2024, found no verifiable evidence that the government or private industry had ever had access to extraterrestrial technology.[1][2]

Background

Congress required AARO to produce a history of government UAP activity. The report also responded to claims, most prominently by former intelligence officer David Grusch in 2023, that the U.S. had secretly recovered non-human craft and run hidden programs to reverse-engineer them. Volume 1 covers the period from 1945 to October 2023. AARO reviewed classified and unclassified government records and interviewed about 30 people.[1][2]

Findings

  • AARO found no verifiable evidence for the claims of reverse-engineered extraterrestrial technology made by interviewees, and said it had been able to disprove most of them.[2][3]
  • None of the programs named by interviewees turned out to be UAP reverse-engineering efforts. In one case an authentic but unrelated program had been unnecessarily amended to include UAP language, but never received any UAP material.[3]
  • Some claims had simple explanations: in one example, what a former officer believed was an extraterrestrial craft was an F-117 stealth fighter.[1]
  • AARO assessed that most historical UAP sightings resulted from misidentification of ordinary objects or phenomena, and that some were probably new or experimental technology. It noted that early-20th-century witnesses were often unfamiliar with emerging technologies such as rockets.[1][3]

Kona Blue

The report described Kona Blue, a proposal submitted to the Department of Homeland Security by people who wanted to investigate whether the U.S. was hiding off-world technology; it was never approved. AARO attributed the persistence of the claims partly to a small, consistent group of believers, some of whom had been involved in the Kona Blue effort, as well as to public distrust of the government and popular culture.[1]

Reactions and Volume 2

Pentagon press secretary Maj. Gen. Pat Ryder said that AARO had found no verifiable evidence of reverse-engineered alien technology. Grusch had not publicly offered evidence for his claims. Volume 2, intended to cover later interviews and research, had still not been published by February 2026, when DefenseScoop noted it was overdue.[1][4]
