Tehran 1976 F-4 Incident (September 19, 1976, Two F-4 Phantoms, Equipment Failure, Weapons System Failed, Declassified DIA Cable)

Overview

ASSESSMENT: The Tehran 1976 incident (September 19, 1976) is one of the MOST COMPELLING MILITARY UAP cases — two Iranian F-4 Phantoms lost all instrumentation and communications when approaching the object, and weapons systems failed when attempting to fire — documented in a declassified DIA cable. September 19, 1976, ~12:30 AM. Tehran, Iran. Imperial Iranian Air Force. INITIAL: 'Command Post received four telephone calls from citizens in Shemiran area.' 'Strange objects in sky — bird-like or helicopter with light.' 'No helicopters airborne.' 'BG Youssef, Assistant Deputy Commander, went outside.' 'Object like star, only larger and brighter.' FIRST F-4 (~1:30 AM): 'Scrambled from Shahrokhi AFB.' 'Proceeded 40 NM north of Tehran.' 'Object visible 70 miles away due to brilliance.' 'AS F-4 CLOSED IN — ALL INSTRUMENTATION AND COMMUNICATIONS (UHF + intercom) LOST.' 'Upon breaking off and turning towards base — all systems returned to normal.' 'As if object no longer regarded aircraft as threat.' SECOND F-4 (~1:40 AM): 'Radar lock-on at 27 NM, 12 o'clock high.' 'Rate of closure 150 knots.' 'Radar return comparable to 707 tanker.' 'Flashing strobe lights in rectangular pattern.' 'ANOTHER OBJECT EMERGED FROM FIRST — headed straight toward F-4 like missile, high rate of speed.' 'PILOT ATTEMPTED TO FIRE AIM-9 MISSILE.' 'WEAPONS SYSTEM ELECTRONICS FAILED.' 'When F-4 turned away, no longer threat — aircraft regained all instrumentation and communications.' EQUIPMENT PATTERN: First F-4: lost all instrumentation/comms when approaching. Second F-4: weapons failed when attempting to fire. Both: systems returned when turning away. 'All electronics operating normally' when examined later. DIA DOCUMENT: 'Defense Intelligence Agency evaluation report.' 'Three-page DOD teletype message.' 'Obtained by Charles Huffer 1977 via FOIA.' 'DIA cable dated 19 September 1976.' ADDITIONAL: 'Object appeared to come out of other side of primary object, going straight down at high speed.' 'Second object went inside turn, returned to primary for perfect rejoin.' Mehrabad Airport ATC observed. Houssain Pirouzi — night supervisor, 13 years experience. CRITICAL: Declassified DIA = official US intelligence document. Two F-4s = not single-aircraft anomaly. Equipment failure pattern = suggests active interference. Weapons failure = couldn't defend. 'No longer threat' = object making decisions. Radar lock-on = 707-sized. Object launched smaller object = mothership pattern. Multiple witnesses = citizens + Brig. Gen. + F-4 crews + ATC. 'Filed away and probably forgotten' = government dismissive attitude.
