AARO
The landscape of Unidentified Anomalous Phenomena (UAP) reporting in the United States is not a random distribution of mysterious events. Instead, it creates a distinct pattern that mirrors the infrastructure of national defense. Data released by the All-domain Anomaly Resolution Office (AARO) reveals a strong correlation between the location of UAP reports and the concentration of military sensors. This correlation suggests that the apparent hotspots for these phenomena are less about where the objects are and more about where the government is looking.
When analyzing the map of UAP sightings, a clear trend emerges. The vast majority of reports originate from areas with intense military activity, such as test sites, fleet operating areas, and major airbases. This phenomenon, known as collection bias, skews the perception of UAP activity. It implies that the dataset is heavily influenced by the presence of advanced detection capabilities. Understanding this bias is essential for anyone attempting to interpret government data on aerial anomalies.
The Mechanics of Collection Bias in Aerial Observation
Collection bias, or selection bias, occurs when the method of gathering data influences the results. In the context of UAP, the United States military operates the most sophisticated sensor networks on the planet. These networks include high-powered radar systems, infrared cameras, and electronic warfare suites designed to detect minute anomalies in airspace. Because these sensors are concentrated in specific geographic regions, such as the southwest training ranges or coastal operating zones, these areas generate the highest volume of reports.
The concept is similar to fishing with a net. If a fisherman only casts a net in a specific part of the ocean, they will only catch fish from that area. It would be incorrect to assume that fish only exist in that one spot; rather, that is simply where the net was cast. Similarly, the Department of Defense (DoD) casts a “sensor net” over its critical infrastructure. Consequently, this is where UAP are caught.
This bias does not mean the sightings are invalid. It means the frequency of sightings in these areas relative to the rest of the country is artificial. The lack of reports in the central United States or rural areas does not necessarily indicate a lack of UAP activity. It indicates a lack of military-grade sensors constantly scanning the sky in those regions.
Geographic Distribution of UAP Reports
The geographic distribution of UAP reports aligns almost perfectly with the footprint of the US military establishment. Analyzing the map provided by AARO highlights three primary zones of activity: the West Coast and Southwest ranges, the East Coast fleet operating areas, and the Southeast.
The Southwest Ranges and Test Sites
The American Southwest, particularly Nevada, Arizona, and New Mexico, hosts some of the most sensitive military testing grounds in the world. This region includes the Nevada Test and Training Range and other vast airspaces reserved for developing advanced aerospace technology. The concentration of reports here is dense.
These ranges are instrumented with ground-based radar and telemetry systems designed to track aircraft performance with extreme precision. Pilots flying in these areas are often testing new platforms or engaging in complex training scenarios. They are on high alert, and their instruments are tuned to detect anything out of the ordinary. When an anomaly enters this airspace – whether it is a foreign drone, a weather balloon, or a genuine UAP – it is far more likely to be detected here than over a cornfield in Nebraska.
East Coast Fleet Operating Areas
Another significant cluster of reports appears off the Atlantic coast, stretching from Virginia down to Florida. This region corresponds with the operating areas of the US Navy’s Atlantic Fleet. Naval aviators conduct daily training sorties in these warning areas.
The prevalence of sightings here gained public attention following the release of videos from Navy aircraft, such as the “Gimbal” and “Go Fast” incidents. These sightings occurred within these specific training blocks. The Navy uses powerful ship-borne radar (like the SPY-1) and airborne radar systems (like those on the F/A-18 Super Hornet and E-2 Hawkeye) to monitor this airspace. The high density of reports is a direct result of these assets operating continuously in the region.
Major Airbases and Special Use Airspace
Beyond the ranges and coastal areas, smaller clusters of reports correlate with major airbases across the continental United States. Locations such as Eglin Air Force Base in Florida or bases in the Pacific Northwest show localized spikes in reporting.
These bases are protected by restricted airspace. Air traffic controllers and defense systems monitor the approach corridors. Any unauthorized intrusion, even by a small commercial drone, triggers a report. This protective posture increases the likelihood that an object will be logged as a UAP if it cannot be immediately identified.
Sensor Technology and Detection Capabilities
The “sensors” mentioned in AARO’s analysis refer to a wide array of electromagnetic detection tools. Understanding how these tools work helps explain why they generate so many reports.
Radar Systems
Radar remains the primary tool for airspace monitoring. Modern Active Electronically Scanned Array (AESA) radars are incredibly sensitive. They can detect small objects at great distances. In recent years, software upgrades to these radar systems have allowed them to filter out less “clutter,” revealing slower, smaller objects that were previously ignored.
In the past, radar filters might have scrubbed out stationary objects or objects moving at wind speed to prevent the screen from being filled with birds or clouds. With adjustments to these filters, pilots began seeing more “tracks” that corresponded to UAP. This technological adjustment contributed to the spike in reports, further reinforcing the link between sensor capability and sighting frequency.
Infrared and Optical Systems
Military aircraft carry advanced targeting pods, such as the ATFLIR (Advanced Targeting Forward-Looking Infrared). These systems use infrared sensors to detect heat signatures. They are designed to lock onto jet engines or missile exhaust.
However, these sensors also pick up heat differentials from other sources. A UAP that is colder than the surrounding air will show up as a dark object (black hot), while a hot object will glow white. The precision of these optical systems allows pilots to obtain visual confirmation of radar tracks. The combination of radar and infrared data creates a multi-sensor corroboration that makes military reports particularly high fidelity compared to civilian eyewitness accounts.
The Role of AARO in Data Collection
The All-domain Anomaly Resolution Office was established to standardize the collection and analysis of these reports. Prior to AARO, reporting was sporadic and often stigmatized. Pilots feared that reporting a UFO would harm their careers. AARO, along with improved procedures within the Navy and Air Force, has worked to reduce this stigma, leading to an increase in the number of reports.
AARO’s mandate includes not just aerial objects, but anomalies in all domains (space, air, land, and sea). However, the bulk of their current dataset remains aerial, driven by the aviation-centric nature of the sensors involved. AARO has consistently emphasized the importance of context. Their analysis of the map serves as a caution to the public and Congress: do not mistake a map of US military bases for a map of alien invasion.
| Sensor Type | Primary Function | Contribution to UAP Reporting |
|---|---|---|
| Active Radar (AESA) | Long-range detection and tracking of aircraft | Detects physical objects, measures speed and altitude; software updates increased sensitivity to small, slow objects. |
| FLIR (Forward-Looking Infrared) | Targeting and visual identification via heat signatures | Provides visual confirmation of radar tracks; allows analysis of propulsion heat (or lack thereof). |
| Electronic Support Measures (ESM) | Detecting radio frequency emissions | Determines if the UAP is emitting radar or radio signals, helping assess if it is a known drone or aircraft. |
| Visual (Pilot Eyewitness) | Human verification of instrument readings | Adds context to sensor data, though subject to optical illusions and human error; highly valued when corroborated by sensors. |
Civilian Reporting and Emerging Trends
While the military dominates the current dataset, the landscape is shifting. The infographic highlights an emerging trend of broader civilian reporting. This shift is driven by the Federal Aviation Administration (FAA) and commercial pilots.
The FAA and Commercial Aviation
Commercial aircraft fly established routes that crisscross the entire country, not just military ranges. As reporting mechanisms for commercial pilots improve, the geographic diversity of the data expands. The inset map in the infographic titled “Emerging Trend: Broader Civilian Reporting” shows a much more diffuse pattern of lights, covering the Midwest, the Plains, and major civilian hubs like Chicago, Atlanta, and Dallas.
Civilian reports generally lack the multi-sensor fidelity of military reports. A commercial airliner does not carry weapons-grade radar or targeting pods. However, the sheer volume of commercial flights means there are thousands of potential observers in the sky at any given moment. Integrating this data provides a necessary counterbalance to the military’s collection bias.
Challenges with Civilian Data
The challenge with civilian data is quality control. A commercial pilot might see a light in the distance, but without the backing of telemetry data, it is difficult to determine distance, size, or speed. Starlink satellites, for example, have been frequently misidentified by civilian pilots as UAP trains. AARO and the FAA must work to filter out these known objects to find genuine anomalies.
National Security and Airspace Safety
The primary driver for the US government’s interest in UAP is not exobiology, but national security. The concentration of reports near military bases is a feature, not a bug, of the defense system. If unknown objects are operating near nuclear sites or fleet exercises, the DoD needs to know what they are.
Adversarial Drones and Espionage
A significant portion of UAP reports likely represent adversarial technology. Foreign powers have an interest in observing US military capabilities. Small, hard-to-detect drones used for espionage would naturally congregate around the very same sensor-heavy areas highlighted on the map.
If a foreign adversary wants to monitor a US Navy exercise, they will deploy surveillance assets to the fleet operating area. Consequently, US sensors will detect them. This reinforces the hotspot appearance. Distinguishing between a foreign surveillance drone and a truly anomalous object is the core technical challenge for AARO.
Flight Safety Hazards
Beyond espionage, UAP pose a flight safety risk. Objects cluttering the airspace, whether balloons, drones, or unexplained phenomena, can collide with aircraft. Military pilots flying at high speeds in training ranges have had near-misses with these objects. This safety imperative forces the military to report every anomaly, further inflating the statistics in these specific regions.
The Influence of Geography on Perception
The geography of the United States plays a role in how UAP are perceived. The vast, empty spaces of the West allow for military testing but also provide a backdrop where strange lights are easily noticeable. In contrast, the light pollution of the East Coast makes visual observation difficult, relying more heavily on instruments.
The “geographic bias” noted by AARO indicates that the data is heavily skewed. This skew complicates scientific analysis. If a researcher wants to understand the behavior of UAP, they need a randomized sample. The current sample is anything but random. It is highly specific to operational areas.
To counter this, independent scientific organizations and groups like NASA (via their independent study team) have recommended using unclassified, calibrated sensors to collect data in non-military areas. This would help determine if UAP are truly global or if they do indeed have an affinity for military sites.
Historical Context of Reporting Hotspots
This is not the first time the US government has tracked UFOs or UAP. Project Blue Book, the Air Force’s study from the 1950s and 60s, also saw clusters of reports. However, in that era, reports were heavily reliant on civilian eyewitnesses, resulting in a map that correlated more with population density than military sensors.
The shift from population-based hotspots to sensor-based hotspots marks a fundamental change in the nature of the phenomenon’s study. It has moved from a sociological event (people seeing things) to a technological event (sensors detecting things). This transition increases the credibility of the data but narrows the scope of where data is collected.
Analyzing the Data: Signal vs. Noise
A critical aspect of AARO’s work is separating signal from noise. “Noise” in this context includes clutter like birds, balloons, airborne debris, and atmospheric phenomena. The sensors near military bases are so sensitive they pick up a tremendous amount of noise.
The Balloon Problem
High-altitude balloons are a frequent source of confusion. They can appear stationary or move with the wind (which can be fast at high altitudes). To a radar operator or a pilot, a metallicized balloon can look like a solid craft. The shoot-down events of February 2023 highlighted how many benign objects are floating in North American airspace.
When sensors are tuned to look for UAP, they find balloons. This contributes to the high report volume in monitored areas. AARO has established a process to cross-reference UAP reports with known balloon launches and commercial flight paths to resolve these cases.
Future of UAP Detection
As sensor technology continues to evolve, the map of UAP reporting will likely change. The rollout of next-generation satellite systems and wide-area surveillance will reduce the reliance on localized assets.
Space-Based Sensors
Satellites offer a vantage point that is less constrained by geography. If the US utilizes space-based assets to track UAP, the collection bias might shift from specific terrestrial ranges to a global perspective. This would provide a more accurate picture of the true distribution of anomalies.
AI and Machine Learning
Artificial Intelligence will play a major role in filtering data. AI algorithms can be trained to recognize the signatures of known aircraft, drones, and birds, automatically filtering them out. This would leave human analysts with only the most compelling cases. It might also allow for the integration of civilian data on a massive scale, correlating millions of data points to find patterns invisible to the human eye.
Summary
The map of US UAP reporting is a map of US military awareness. The concentration of reports along the coasts and in the southwest ranges is a direct result of the density of advanced sensors and personnel in those areas. This collection bias is the defining characteristic of the current dataset. It demonstrates that the government sees what it looks for, and it looks most intently at its own sensitive facilities.
While this bias complicates the search for the unknown, it underscores the rigor with which the US military monitors its airspace. The transition to broader civilian reporting and the application of new technologies promises to widen the aperture, potentially revealing whether these phenomena are truly ubiquitous or if they specifically target the machinery of national defense. As AARO continues its work, disentangling the observer from the observed will remain the primary analytical challenge.

Appendix: Top 10 Questions Answered in This Article
Why are UAP reports concentrated in the Southwest and East Coast?
These areas host major military training ranges and fleet operating areas. The high volume of reports is due to the high density of advanced sensors and military personnel constantly monitoring these specific airspaces.
What is collection bias in the context of UAP reporting?
Collection bias refers to the skew in data caused by the location of detection equipment. Because the military has the best sensors and they are located in specific areas, those areas generate the most reports, regardless of the actual global distribution of UAP.
What role does the FAA play in UAP reporting?
The Federal Aviation Administration facilitates reporting from commercial pilots. This data helps broaden the geographic scope of sightings beyond military ranges, covering civilian air routes and major cities.
Are the sightings in these hotspots evidence of alien activity?
Not necessarily. The concentration of reports correlates with sensor density, not necessarily the presence of extraterrestrial craft. Many reports turn out to be ordinary objects like drones or balloons that are detected because of the intense surveillance in these zones.
What types of sensors are used to detect UAP?
The military uses Active Electronically Scanned Array (AESA) radar, Forward-Looking Infrared (FLIR) cameras, and electronic support measures. These technologies allow for the detection of small, distant, or heat-emitting objects that human eyes might miss.
Why is the Department of Defense interested in UAP?
The primary concern is national security and airspace safety. Unidentified objects near nuclear sites or military bases could be foreign espionage drones or hazards to flight safety, requiring immediate identification.
How does AARO contribute to understanding UAP?
The All-domain Anomaly Resolution Office standardizes reporting and analysis. They filter data, resolve cases that have prosaic explanations (like balloons), and analyze the remaining anomalies to identify potential threats or new technologies.
What is the difference between active and passive sensors?
Active sensors, like radar, send out a signal and measure the reflection. Passive sensors, like infrared cameras, simply detect energy (heat or light) emitted by the object. Both are used together to corroborate UAP sightings.
How do balloons and drones complicate UAP data?
Balloons and drones are common in US airspace and can mimic the appearance of UAP on radar or visually. They constitute a large portion of the “noise” that analysts must filter out to find genuine anomalies.
What is the “emerging trend” in UAP reporting shown on the map?
The emerging trend is the increase in reports from non-military sources, specifically commercial pilots. This trend is gradually filling in the blank spots on the map, providing data from areas where the military does not have a heavy sensor footprint.
Appendix: Top 10 Frequently Searched Questions Answered in This Article
What does the UAP reporting map show?
The map displays the geographic locations of UAP sightings reported to the US government. It highlights intense clustering around military bases, test ranges, and naval operating areas, indicating a strong correlation with sensor locations.
Where are the most UFO sightings in the US?
Data indicates the highest volume of government-tracked sightings occurs in the Southwest (Nevada, Arizona) and off the East Coast (Virginia to Florida). These correspond to the Nevada Test and Training Range and Navy fleet operating areas.
What is the AARO?
AARO stands for the All-domain Anomaly Resolution Office. It is the office within the Department of Defense responsible for investigating and resolving reports of unidentified anomalous phenomena across air, sea, and space.
Why do pilots see UAP more than regular people?
Pilots operate at high altitudes with unobstructed views and access to sophisticated instruments like radar. They are also trained to scan the horizon and are flying through the very airspace where these objects are most easily detected.
Is the government hiding UAP evidence?
While much data remains classified due to the sensitivity of the sensors used to collect it, AARO has been releasing unclassified analysis. They argue that the patterns seen are largely a result of where they are looking, rather than a cover-up of where objects are hiding.
What is the difference between UFO and UAP?
UFO (Unidentified Flying Object) is the older term, often associated with pop culture and aliens. UAP (Unidentified Anomalous Phenomena) is the modern, scientific term used by the government to include objects in water or space and to destigmatize the study.
Can radar detect UFOs?
Yes, modern military radar is highly sensitive and can detect UAP. Recent software updates have improved the ability of radar systems to track small, slow-moving objects that were previously filtered out as clutter.
Are UAP a threat to national security?
They are considered a potential threat. Whether they are foreign drones conducting surveillance or unexplained phenomena creating flight hazards, the military treats any unauthorized entry into restricted airspace as a security issue.
How accurate is UAP data?
The accuracy varies by source. Military reports backed by multiple sensors (radar, infrared, visual) are considered high fidelity. Civilian reports, while numerous, often lack the instrument data needed to confirm the object’s size, speed, or origin.
What causes bias in UAP statistics?
Bias is caused by the uneven distribution of sensors. Since the military only has high-tech scanners in certain places, they only generate statistics for those places, creating a skewed representation of where UAP activity might actually be occurring.
