Complete timeline of UAP and alien disclosure events from 2017 to June 2026. Congressional hearings, whistleblowers, document releases, and what comes next.
▶ Live TrendsThe modern UAP disclosure era began in December 2017 when the New York Times revealed the existence of AATIP — a secret Pentagon program studying UAP. The accompanying release of Navy videos showing unidentified craft stunned the public and forced government acknowledgment.
The US Navy officially confirmed the authenticity of UAP videos in 2019. In 2021, the Pentagon established the UAP Task Force and released its first official report acknowledging 144 UAP incidents that could not be explained — a historic admission.
Congress held multiple UAP hearings in 2022 and 2023. The watershed moment came in July 2023 when David Grusch testified under oath that the US government possesses recovered non-human craft and biological material — triggering a global surge in alien file searches.
Following Grusch's testimony, pressure for full disclosure intensified. Multiple document releases and Congressional mandates for transparency have kept UAP in the public consciousness through 2026, with search interest reaching record highs ahead of expected June 2026 announcements.
