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 1 UNCLASSIFIED All-domain Anomaly Resolution Office U.S. Department of Defense (U) Case: “Southeast Asia Triangles” Case Resolution | 17 March 2023 (U) Case Essentials (U) Six triangular objects in a formation were originally flagged as potentially anomalous and potentially posing a risk to navigation (U) Location: Southeast Asia (U) Date: 30 August 2017 (U) Altitude: N/A (U) Shape: Six dark triangles (U) Reporter: An Intelligence Community Member (U) Sensor: Satellite imagery (U) Behavior: Noted as possible risk to navigation (U) Case Status: Resolved; Objects are fishing nets on the ocean surface (U) Case Overview (U) AARO assesses that the subjects of the “Southeast Asia Triangles” case from 2017 almost certainly are cone-shaped, static fishing nets floating on the surface of the ocean. This conclusion is based on a thorough review of the evidence by AARO’s Intelligence and Science and Technology (S&T) Partners. (U) The image was originally flagged as containing potentially anomalous objects and posing a risk to navigation. Additional imagery of the area from 2023 was discovered and collected. (U) Both the Intelligence and S&T teams compared the size, shape, and location of the initial image to existing and subsequent images in the same region, and compared it to libraries of known morphologies. (U) Intelligence Assessment (U) AARO’s Intelligence partners examined the image and compared it to other imagery. Specifically, they located clearer images in the vicinity of the objects in question. (U) The images from 2023 display several triangles and were confirmed to be static, cone-shaped fishing nets. (U) These triangular fishing nets were compared to the black triangles from the 2017 imagery and it was confirmed that they are all are approximately the same size of about 11m x 7m.
