TL;DR

Declassified DIA report explicitly calls this case 'a classic which meets all the criteria for a valid study of the UFO phenomenon' after an IIAF F-4 Phantom's weapons systems and instrument panel failed at the moment of AIM-9 missile selection during a radar-confirmed intercept over Tehran.

Confirmed

  • DIA intelligence report (DIA/ST-CS-01-776-76) was produced, declassified, and rates the incident highly credible
  • Two IIAF F-4 Phantom aircraft were scrambled; both crews experienced instrument and communications failures at proximity to the object
  • Mehrabad Airport control tower confirmed an unknown radar return before the scramble
  • General Parviz Jafari testified publicly about the incident including at the 2007 National Press Club

Unresolved

  • ?Whether the instrument failures resulted from directed electromagnetic interference or coincidental equipment failures
  • ?Identity of the sub-object that appeared to land south of Tehran - ground search found nothing
  • ?Whether a classified U.S. or Soviet program could explain the object's performance and the rapid U.S. DIA response
  • ?Full extent of U.S. intelligence records beyond the released DIA report

Strongest mundane explanation

The initial visual sighting may have been Jupiter (confirmed visible and bright over Tehran that night), with subsequent instrument failures caused by electronic warfare jamming from a classified U.S. or Soviet asset, but the DIA report itself rejects the astronomical explanation based on the radar return showing a 707-sized object, and two independent aircraft experiencing identical failures strains a coincidental malfunction explanation.

An Imperial Iranian Air Force F-4 Phantom scrambled to intercept a bright object over Tehran experienced complete electronic failure when approaching the target. A second F-4 also scrambled, achieved radar lock, and attempted to fire an AIM-9 missile - at which point all weapons systems and instrument panels went dark. When the pilot broke off the attack, systems resumed. A declassified Defense Intelligence Agency report documented the incident and assessed it as a genuine encounter with an unknown craft. The DIA document is one of the most specific and compelling official UAP records released by the US government.

Key Facts

  • Date: September 19, 1976, approximately 12:30 AM local time
  • Initial reports came from civilian phone calls to Mehrabad Air Base reporting a bright object over Tehran
  • First F-4 scrambled; pilot reported loss of all instruments and communications when approaching - turned back and systems immediately restored
  • Second F-4 scrambled by General Parviz Jafari; achieved radar lock on an object roughly the size of a 707 tanker
  • A smaller object separated from the main object and approached the second F-4; Jafari attempted to fire an AIM-9 missile
  • At the moment of weapons selection, all systems failed - instruments, radio, weapons control all went dark
  • When Jafari broke off the attack and descended, all systems immediately restored
  • A second smaller object separated from the main object and impacted the ground with a bright flash but no explosion
  • The US Defense Intelligence Agency (DIA) produced a classified report assessing the incident
  • The DIA document was later declassified and released - it is considered one of the most specific official UAP documents in the public record
