USS Russell combat information center captured night-vision footage showing triangular or pyramid-shaped UAPs flying in formation over the ship at approximately 700 feet. The DoD authenticated the footage in 2021. The pyramid appearance is attributed in some Navy analysis to a bokeh artifact from the night-vision optics — but the objects themselves remain unidentified.
