The All-domain Anomaly Resolution Office (AARO) has received a formal unresolved UAP report from U.S. Central Command describing an encounter over Greece in January 2024, in which a diamond-shaped aerial object was detected moving at approximately 434 knots and proved visible only through short-wave infrared (SWIR) sensors. The report, designated DOW-UAP-PR28, is accompanied by one minute and five seconds of multi-sensor video footage captured from a U.S. military platform.
Sensor Characteristics and Video Record
According to the Department of War release, the footage opens with a split-screen display showing simultaneous electro-optical and SWIR feeds for the first ten seconds. An area of contrast becomes distinguishable in the center of the electro-optical frame at approximately the four-second mark, though the SWIR feed provides the clearer signal.
At the ten-second mark, the operator transitions to a full-screen SWIR view. The object remains generally centered in the sensor field of view through most of the recording. The release describes the anomaly's appearance at the 55-second mark as resembling "an inverted teardrop with a vertically linear trailing mass suspended below."
The sequence ends with a significant observational gap: at 56 seconds, the operator switches to the visible-spectrum modality, at which point the object is lost against the background. A subsequent switch back to SWIR in black-hot mode, from 57 seconds through the end of the clip, does not result in reacquisition of the contact. The object is not recovered on any sensor before the footage concludes.
Key Anomalous Characteristics
The accompanying mission report, DoW-UAP-D7, characterizes the object as diamond-shaped and traveling at roughly 434 knots — a speed broadly consistent with high-performance military aircraft, though the SWIR-exclusive detection profile complicates that comparison. Conventional aircraft and most drones produce detectable signatures across multiple sensor bands, including visible and electro-optical. An object that registers clearly in short-wave infrared while remaining invisible to electro-optical and visible-spectrum sensors is an atypical finding that warrants further investigation, though no analytical conclusion has been drawn by reporting authorities.
The Department of War release includes an explicit disclaimer that its video description "is provided for informational purposes only" and that readers "should not interpret any part of this description as reflecting an analytical judgment, investigative conclusion, or factual determination regarding the described event's validity, nature, or significance." That framing is consistent with AARO's standard practice of releasing unresolved case materials without prejudicing ongoing analysis.
Reporting Pathway and Status
The case follows the reporting chain established under the National Defense Authorization Act provisions that created AARO, with Central Command acting as the originating command. The designation of the report as "unresolved" indicates that AARO has not attributed the observation to any known aircraft, natural phenomenon, or sensor artifact as of the time of publication.
The Greece location adds a noteworthy geographic dimension. The eastern Mediterranean and Aegean region is an area of sustained military activity involving U.S., NATO, and regional forces, as well as commercial air traffic corridors. The release does not specify the precise location, altitude, or operational context of the collecting platform, nor does it identify the type of aircraft or sensor system involved beyond the sensor modalities described in the footage log.
No named analysts or investigators are quoted in the source material, and AARO has not publicly issued a resolution assessment for this case. The report stands, for now, as an unresolved entry in the office's growing catalog of documented encounters — notable primarily for its sensor signature anomaly and the clean documentation of the moment the object was lost.
