What Is AARO? How the United States Government Investigates UFOs and UAP
For decades, the subject of UFOs existed somewhere between military secrecy, unexplained sightings, scientific curiosity, and popular culture. Today, the conversation has changed. The United States government openly acknowledges that unidentified objects and phenomena are being reported by military personnel, pilots, and other observers, and it has established a dedicated office to investigate them.
That office is the All domain Anomaly Resolution Office, better known as AARO.
But what exactly is AARO?
What does AARO investigate?
How does the United States government investigate UFO sightings, and does AARO believe any UFOs are extraterrestrial spacecraft?
The answers are more complicated, and in some ways more interesting, than the popular image of a secret Pentagon UFO program.
AARO is a United States government organization focused on detecting, analyzing, identifying, and attempting to resolve Unidentified Anomalous Phenomena (UAP). Its work covers phenomena observed across multiple environments, including the air, maritime environments, and space. AARO's stated mission is to reduce the possibility of technological or intelligence surprise by identifying and mitigating UAP near areas important to national security.
Understanding what AARO actually does is essential for anyone trying to separate documented UFO evidence from speculation, rumors, misidentifications, and extraordinary claims.
What Is AARO and What Does the Name Mean?
AARO stands for All domain Anomaly Resolution Office. It was established by the United States Department of Defense in 2022 as the government's centralized organization for addressing UAP. The phrase “all domain” is important.
Traditional UFO discussions often focus exclusively on objects seen in the sky. Modern UAP investigations are broader. An anomalous observation could potentially involve the atmosphere, oceans, land environments, or space. Consequently, AARO's mandate is designed around investigating reports across multiple domains rather than treating every case as simply an unidentified object in the sky.
AARO's official mission is to synchronize the detection, identification, attribution, and mitigation of UAP in the vicinity of national security areas. Its stated vision emphasizes detection, tracking, analysis, and management using scientific and intelligence standards.
This makes AARO fundamentally different from the fictionalized idea of a government agency whose primary purpose is to prove the existence of aliens.
Its primary responsibility is much more practical: figure out what people are observing and determine whether those observations represent a potential threat or an identifiable object or phenomenon.
When Was AARO Created?
AARO was established in July 2022 following growing congressional and public interest in UAP reports involving military personnel and national security areas. The Department of Defense announced the creation of the All domain Anomaly Resolution Office on July 20, 2022. Its creation represented an important change in how the United States government publicly approached UFO investigations.
The government had investigated unusual aerial observations long before AARO existed. Projects such as Project Blue Book, as well as later intelligence and military efforts, examined reports of unidentified objects. AARO's historical review has examined official U.S. government investigations dating back to 1945.
The difference is that AARO represents a modern effort to centralize UAP related investigations across the Department of Defense and intelligence community.
That historical continuity matters. The modern UAP investigation program did not suddenly appear because the government discovered aliens. Instead, it developed from a much longer history of military aviation, intelligence, national security, sensor technology, and unexplained sightings.
What Is the Difference Between a UFO and a UAP?
The terms UFO and UAP are often used interchangeably, but they have different histories.
UFO stands for Unidentified Flying Object. The phrase became deeply embedded in popular culture and is still widely used when people search for information about unexplained objects in the sky.
UAP stands for Unidentified Anomalous Phenomena in the terminology currently used by the United States government. The newer terminology is intentionally broader. A UAP does not necessarily mean that an object is a spacecraft. It means that an observation has not yet been sufficiently identified or attributed based on the available information. That distinction is one of the most important concepts in modern UFO research.
Unidentified does not mean extraterrestrial.
An object can remain unidentified because the available video is blurry, the observer lacks sufficient information, the sensor data is incomplete, atmospheric conditions distort perception, or there is insufficient information to determine exactly what was observed.
AARO itself explains that many UAP reports remain unidentified simply because sensors did not collect enough information to make a positive attribution. This is why a scientifically responsible investigation should treat “unidentified” as a starting point rather than a conclusion.
How Does the United States Government Investigate UFOs?
The United States government's approach to UAP investigation is fundamentally an intelligence, scientific, and data analysis problem.
When a UAP is reported, investigators want to determine what was observed, where it was observed, when it was observed, how it appeared to move, what sensors detected it, and whether other information can independently confirm the observation.
This is why sensor data is so important to UAP investigations.
A photograph alone may provide only limited information. A high quality investigation could potentially combine electro optical imagery, infrared data, radar information, GPS coordinates, aircraft telemetry, weather information, air traffic data, satellite tracking, astronomical information, and other intelligence sources.
AARO specifically emphasizes the importance of high quality, uncompressed imagery, associated metadata, timestamps, geographic coordinates, and information about the sensor itself. This allows investigators to compare an observation against known aircraft, satellites, balloons, astronomical objects, and other potential explanations.
In other words, the most interesting UFO investigation is not necessarily the one with the strangest story. It may be the case with the best data.
What Does AARO Look For in a UAP Case?
AARO investigators are essentially trying to move an observation from uncertainty toward attribution. That process can involve examining the object's apparent movement, morphology, altitude, environmental conditions, sensor characteristics, and surrounding activity.
Investigators may ask whether the object corresponds to an aircraft, drone, balloon, satellite, rocket, bird, astronomical object, atmospheric phenomenon, sensor artifact, or another known explanation.
This approach has already produced numerous resolutions. AARO's current UAP reporting database shows that many closed cases have ultimately been attributed to ordinary objects such as balloons, satellites, unmanned aircraft systems, aircraft, birds, and other conventional sources.
That finding should not be interpreted as meaning every UAP report is easily explainable.
Instead, it demonstrates something fundamental about scientific investigation: the purpose of an investigation is to test possibilities rather than automatically accept the most extraordinary explanation.
What Happens When AARO Cannot Identify a UFO?
One of the biggest misconceptions about UAP investigations is that a case being “unresolved” means investigators believe it represents alien technology.
It does not.
An unresolved case simply means that the available evidence is not sufficient to establish a reliable identification. This distinction became particularly important in AARO's latest reporting.
The Fiscal Year 2025 Consolidated Annual Report on Unidentified Anomalous Phenomena was released by AARO in July 2026. The report represents the newest consolidated government assessment publicly available as of August 2026, although its information cutoff was May 30, 2025.
AARO reported receiving 319 UAP reports during the period covered by the report, bringing its overall holdings to approximately 1,870 reports. The cases covered multiple domains, including air, space, and maritime observations. AARO resolved 114 of the newly received reports as conventional objects or phenomena, while other cases remained under review or lacked sufficient information for a definitive resolution.
That is a crucial distinction.
There is a large difference between saying: “We don't know what this was,” and saying: “We know this was an extraterrestrial spacecraft.”
AARO's public evidence does not establish the second conclusion.
Does AARO Investigate Alien UFOs?
This is one of the most common questions surrounding AARO. The short answer is that AARO investigates UAP reports, not “alien spacecraft” as an established category.
AARO's FAQ states that the Department of Defense has not found evidence of extraterrestrial technology and that its examination of UAP sightings remains ongoing.
That statement is significant because it establishes the government's current public position.
However, it is equally important not to overinterpret it.
AARO saying that it has not found evidence of extraterrestrial technology does not prove that extraterrestrial life does not exist. It means that the evidence examined by AARO has not demonstrated that UAP are extraterrestrial technology.
Those are two very different claims.
The scientific question of whether life exists elsewhere in the universe is vastly larger than the question of whether any particular UFO sighting represents an extraterrestrial spacecraft.
What Did AARO Find in Its Historical UFO Investigation?
AARO has also examined the history of United States government involvement with UFOs and UAP.
Its Historical Record Report, Volume I, reviewed official United States government investigations dating back to 1945, examined classified and unclassified archives, and included interviews with individuals claiming knowledge of alleged government involvement with UAP and extraterrestrial technology. The report illustrates why historical UFO claims can be difficult to evaluate.
Throughout the Cold War and subsequent decades, the United States developed highly classified aircraft, surveillance platforms, weapons systems, sensors, balloons, and other technologies. Observers who did not know about those programs could interpret unfamiliar objects as something extraordinary.
AARO's historical research therefore considers not only alleged UFO sightings, but also the development and secrecy surrounding advanced government technologies. This does not mean every historical UFO case was secretly a military aircraft. It means that any serious historical investigation has to consider that possibility alongside other explanations.
The 2026 AARO Report and the Virginia Coast UAP Case
The newest AARO report also contains an example of why unresolved UAP cases continue to attract attention. The FY2025 report disclosed a United States Navy report involving approximately 100 airborne UAP and two likely uncrewed surface systems off the coast of Virginia. AARO stated that the case remained under active investigation in coordination with the reporting unit.
The case is notable because it involves a military report rather than merely an anecdotal civilian sighting. But there is an important limitation. The publicly available information does not provide enough sensor data to determine what the objects actually were.
Consequently, the correct conclusion is that a United States Navy related UAP report involving a large number of airborne objects and two likely uncrewed surface systems was documented and remained under investigation.
It is not evidence that approximately 100 alien spacecraft were operating off the American coast. That distinction demonstrates exactly why primary source UAP research matters.
Why Are So Many UFO Cases Difficult to Solve?
The biggest obstacle facing modern UAP investigations may not be a lack of sightings. It may be a lack of high quality data. A witness can accurately describe something they saw while still being unable to determine its distance, size, speed, altitude, or actual trajectory. Human perception is extremely good at recognizing patterns but not necessarily at accurately measuring unfamiliar objects in the sky.
Sensors have their own limitations. Infrared systems, radar, cameras, and other instruments can produce incomplete or ambiguous information. Compression can introduce artifacts. Optical effects can distort apparent movement. Relative motion can make stationary or slowly moving objects appear to accelerate dramatically.
AARO has explicitly identified insufficient timely and actionable sensor data as a continuing limitation on its ability to resolve UAP cases. This is perhaps one of the most important lessons from modern UAP research. Better answers require better evidence.
Are UAP a Threat to National Security?
AARO's mission is not primarily about determining whether aliens exist. It is also about national security.
An unidentified object operating near a military installation, aircraft, naval vessel, nuclear facility, or other sensitive location may deserve investigation regardless of whether it eventually turns out to be a balloon, drone, satellite, aircraft, sensor artifact, or something genuinely unusual.
From a defense perspective, the identity of an object matters. A previously unknown drone could represent a security concern. A foreign surveillance platform could represent an intelligence threat. A sensor malfunction could create an operational hazard. An ordinary satellite could be mistaken for something anomalous.
This is why the United States government treats some UAP reports seriously without necessarily concluding that they are extraterrestrial.
The question is not simply, “Are aliens here?”
The national security question is often much more immediate: “What was operating in this area, and why didn't we identify it?”
What Does AARO Know About Extraterrestrial Technology?
Based on AARO's publicly released findings, there is currently no confirmed evidence that UAP represent extraterrestrial technology.
The FY2024 annual report stated that AARO had discovered no evidence of extraterrestrial beings, activity, or technology. It also reported that cases resolved during that period were attributed to prosaic objects such as balloons, birds, and unmanned aircraft systems. The FY2025 reporting continues to distinguish between cases that have been resolved and cases that remain unresolved.
That distinction is essential. An unresolved UAP is a mystery. A mystery is not automatically evidence of aliens. At the same time, unresolved cases deserve continued investigation precisely because the available evidence has not yet produced a satisfactory explanation.
That is where responsible UFO research becomes genuinely fascinating.
Why AARO Matters to UFO and UAP Research
AARO matters because it represents one of the most significant developments in the history of official United States government UFO investigations. For decades, discussions about UFOs were often dominated by conflicting testimony, classified programs, blurry photographs, conspiracy theories, sensational claims, and limited access to government records.
Today, researchers can examine an increasing amount of official documentation, government reports, UAP imagery, congressional materials, historical records, and case resolution information.
AARO's website provides access to official UAP imagery, reporting trends, records, congressional products, historical research, and other materials. That growing public record gives researchers an opportunity to ask better questions.
Instead of simply asking, “Was this a UFO?”
Researchers can ask:
What did the sensor actually detect?
What information was available to investigators?
What conventional explanations were tested?
What evidence supports or contradicts each explanation?
What remains genuinely unexplained?
And perhaps most importantly: What new evidence would allow the case to be resolved?
The Future of Government UFO Investigations
The future of UAP research is likely to depend less on dramatic photographs and more on high quality data.
As cameras, radar systems, infrared sensors, satellites, autonomous aircraft, artificial intelligence, and tracking networks become increasingly sophisticated, the ability to detect unusual objects should continue to improve.
At the same time, the number of potential sources of confusion is increasing. Thousands of satellites now occupy Earth orbit. Commercial and military drones are increasingly common. Rocket launches create unusual atmospheric phenomena. New aircraft technologies can look unfamiliar. Advanced sensors can detect objects that previous generations of observers could never have seen.
The sky is becoming more technologically complicated. That makes organizations such as AARO increasingly important. The central challenge is not simply identifying something strange. It is determining whether the strangeness comes from an unusual object, an unusual environment, a sensor limitation, an unfamiliar technology, or something genuinely anomalous.
What Is the Most Important Thing to Understand About AARO?
AARO does not exist to prove or disprove the existence of extraterrestrial life.
It exists to investigate anomalous observations and reduce uncertainty, particularly when those observations could affect national security or flight safety. Its public record currently shows a mixture of resolved cases, unresolved cases, incomplete data, historical investigations, and ongoing analysis.
Some reports become ordinary explanations. Others remain unresolved because the available evidence is insufficient. And a small number of cases may continue to demand additional investigation because they contain unusual characteristics or potentially important national-security implications. That is exactly why the subject of UAP deserves careful attention.
The most responsible position is neither to declare every unidentified object an alien spacecraft nor to dismiss every unexplained observation without examining the evidence.
The real story is in between.
AARO gives researchers a rare opportunity to examine how the world's most powerful military and intelligence establishment investigates objects it cannot immediately identify.
And for anyone seriously interested in UFOs, UAP, government investigations, extraterrestrial possibilities, and the unexplained, that evolving evidence may be far more fascinating than any simple answer.
The search for the truth begins with a deceptively simple question: What exactly did we see?
And sometimes, the most honest answer is still: We don't know, yet.
