This is a case resolution report dated 17 March 2023 from the All-domain Anomaly Resolution Office (AARO) of the U.S. Department of Defense on the "Southeast Asia Triangles" case. Satellite imagery from 30 August 2017, reported by an Intelligence Community member, showed six dark triangles and was flagged as a possible risk to navigation. AARO's intelligence and science and technology partners compared it with imagery from 2022 and 2023. They concluded the objects were almost certainly static, cone-shaped fishing nets on the water, about 11 by 7 meters each.
UNCLASSIFIED 2 UNCLASSIFIED (U) AARO’s Intelligence partners have high confidence in their identification of these objects and assess they do not pose a hazard to navigation. (U) Science & Technology Assessment (U) Three of AARO’s S&T partners agree that the objects imaged in 2017 are fishing nets. (U) S&T Partner One specifically noted that subsequent images were especially clear; the location and the size comparison were critical in determining the assessment. (U) S&T Partner Two acquired and analyzed other images of the same geographical area which revealed multiple similar triangular shapes taken in late 2022 and early 2023. These images also show significant downstream turbidity, confirming that these nets are on the water. (U) S&T Partner Three also found stock footage of fishing nets on the same river, which confirms the underlying analysis. (U) Figure 1: “Southeast Asia Triangles” Comparison
