US will deploy Gremlin, a cutting-edge UFO surveillance system, in early 2025. Developed by Georgia Tech Research Institute, it integrates 2D and 3D radar with electro-optical and infrared telescopes to track Unidentified Anomalous Phenomena. After successful testing in March, it'll begin a 90-day trial at a national security site. The Pentagon has, however, maintained that aliens don't exist.
