Modern U.S. Air Force UAP Encounters (2004–2026)
The U.S. Air Force has contributed dozens of modern UAP encounters to the Pentagon's PURSUE catalog — from the 2017-2026 CENTCOM mission report series through the 2023 F-16 Lake Huron shootdown and the 2025 ODNI senior-IC-officer helicopter narrative on a Western U.S. test range.
The U.S. Air Force is the originating authority for a substantial fraction of the modern UAP encounters in the Pentagon's PURSUE catalog. USAF UAP records span the 1947-1948 foundational era (the Wright Field Air Material Command memorandum, the 1948 Top Secret Air Force Intelligence report opening 'For some time we have been concerned by the recurring reports on flying saucers') through the 1948-1950 Sandia Base green-fireball investigation (declassified in Release 02 as DOC-141, with Dr. Lincoln LaPaz's Fourth, Sixth, and Seventh Reports) through the modern CENTCOM mission report series (Iraq May 2022, Syria July 2022, Mediterranean January 2024) and the February 12, 2023 F-16C Lake Huron engagement (DOW-UAP-PR071). The USAF UAP record concentrates institutional weight on incidents involving fighter or transport aircraft, missile-warning radar, and aircrew-witness reports — distinct from the U.S. Navy record's carrier-aviation, ATFLIR, and AN/SPY-1 emphasis.
“For some time we have been concerned by the recurring reports on flying saucers.”
Foundational era (1947–1950)
The USAF's foundational UAP record opens with the 1947 Wright Field Air Material Command (AMC) memorandum formally acknowledging 'continued and recent reports from qualified observers concerning this phenomenon' — the predecessor document to Project SIGN. The 1948 Top Secret Air Force Intelligence report opens with the line 'For some time we have been concerned by the recurring reports on flying saucers' and established the institutional framing that carried through Projects SIGN, GRUDGE, and Blue Book. The 1948-1950 Sandia Base green-fireball investigation under Dr. Lincoln LaPaz at the Armed Forces Special Weapons Project followed.
Project SIGN, GRUDGE, and Blue Book (1948–1969)
The USAF's UFO investigation programs ran continuously from 1948 to 1969 under three successive names: Project SIGN (1948), Project GRUDGE (1949-1951), and Project Blue Book (1952-1969). Blue Book investigated 12,618 cases over its 17-year run, of which 701 remained unidentified at termination. The 1968 Condon Report ('Scientific Study of Unidentified Flying Objects'), commissioned by the USAF and conducted at the University of Colorado, concluded that further study 'cannot be justified' — directly preceding the December 1969 Blue Book termination.
Modern CENTCOM mission reports (2022–2024)
USAF modern UAP encounters dominate the CENTCOM AOR. Notable PURSUE entries include DOW-UAP-D14 (Iraq May 2022 mission report, declassified by Major General Richard A. Harrison, USCENTCOM Chief of Staff, on October 7, 2025), the Syria July 2022 series including DOW-UAP-PR051 (the 'instant acceleration' clip), DOW-UAP-PR050 (the four-UAP formation over Iran, August 26, 2022), and additional infrared captures spanning 2021-2024. All CENTCOM USAF clips are hosted on DVIDS.
February 12, 2023 F-16 Lake Huron shootdown (DOW-UAP-PR071)
On February 12, 2023, a USAF Air National Guard F-16C engaged and downed an unidentified object over Lake Huron in the U.S. Northern Command area of responsibility — the fourth of four shootdowns during the February 4-12, 2023 high-altitude object series. The 46-second gun-camera infrared video was declassified under PURSUE Release 02 as DOW-UAP-PR071, with AARO's description noting 'a kinetic interaction between two distinct areas of contrast.' This is the USAF's most-publicized modern UAP engagement on the public record.
2025 ODNI helicopter narrative (DOC-142)
Although authored by a senior U.S. Intelligence Community official and originating with ODNI rather than USAF, the late-2025 Western U.S. test-range helicopter encounter declassified as DOC-142 occurred during USAF-coordinated test-range operations and involved fighter jets entering the airspace. The narrative is included in the modern USAF context because the test range is USAF-administered and the F-15/F-16 fighter participation is the USAF's operational signature on the encounter.
