The Pentagon’s All‑Domain Anomaly Resolution Office (AARO) briefed the Senate Armed Services Subcommittee on Emerging Threats and Capabilities on Tuesday, offering a mixed assessment of the department’s unidentified anomalous phenomena (UAP) investigations. New director Dr. Jon Kosloski, who took the helm in August, told lawmakers that while a number of recent reports have been explained through conventional means, “we do have some very anomalous objects.” His remarks, delivered during a hearing chaired by Sen. Kirsten Gillibrand (D‑NY), underscored both the progress made in parsing the growing data set and the lingering gaps that still demand more sophisticated sensor capabilities.
Kosloski highlighted three cases the office now classifies as resolved. The first, dubbed “The Puerto Rico Object,” involved a 2013 video captured from a U.S. Customs and Border Protection aircraft near Aguadilla. After a “high‑confidence” analysis, AARO concluded the luminous shape was most likely a pair of balloons or sky lanterns drifting at roughly seven knots. The second case revisited the 2017 Navy “Go Fast” footage, which had sparked extensive public debate. Using trigonometric and geospatial techniques, AARO determined the object was about 13,000 feet aloft, and that apparent high speed was an optical illusion caused by parallax. A third example, a 2018 drone recording of Mount Etna’s eruption, showed a small point of light that, after detailed three‑dimensional modeling, was found to be 170 meters from the volcanic plume rather than penetrating it. These findings illustrate how rigorous analysis can strip away sensational interpretations and attribute many sightings to mundane sources.
The director’s testimony turned to the cases that remain unresolved. Among the most striking, Kosloski described an incident reported by law‑enforcement officers in the western United States in which a “large orange orb” was observed hovering at low altitude. The object’s size, color, and apparent lack of propulsion defied easy categorization, prompting AARO to label it “anomalous” pending further data. Kosloski also noted a diversity of morphologies in recent reports—ranging from spherical orbs and elongated cylinders to triangular shapes—suggesting that the phenomena do not conform to a single, easily identifiable class of aerial vehicle.
In addressing why some cases persist as mysteries, Kosloski pointed to limitations in the existing sensor suite. “Our ability to resolve these objects is directly tied to the fidelity of the data we collect,” he said, emphasizing the need for “advanced, multi‑spectral, high‑resolution sensors” that can capture kinetic, thermal, and electromagnetic signatures simultaneously. He urged the Department of Defense and allied agencies to invest in next‑generation detection platforms, noting that many of the anomalous sightings occur in environments—such as high‑altitude airspace or near volcanic plumes—where conventional radar and visual systems are less effective.
Kosloski concluded by reaffirming AARO’s commitment to transparency and to fostering a reporting culture within the military and intelligence communities. He said the office has taken steps to protect whistleblowers and to ensure that personnel who encounter UAPs feel “comfortable coming forward and speaking to AARO.” While the director cautioned against assuming every unexplained sighting is evidence of advanced foreign technology or extraterrestrial craft, his admission that “some very anomalous objects” remain under investigation signals that the Pentagon’s UAP program is still evolving. The hearing, therefore, serves both as a status update on resolved cases and a call for greater technical resources to address the enduring uncertainties that continue to capture public and congressional attention.
