The first sortie involved an experienced crew, but technical malfunctions forced a return before interception. A second F-4, piloted by Major Parviz Jafari, was deployed from Shahrokhi Air Force Base. Upon nearing the object, both jets’ radar locks briefly registered an unknown target exhibiting abnormal speed and maneuverability—beyond the capabilities of known aircraft at the time.
Military officials coordinated closely with local surveillance stations and air traffic controllers. Standard protocol required confirmation with the Federal Aviation Administration if unusual aerial activity threatened airspace security, but immediate focus remained on direct military engagement.
Difficulty in Weapons Deployment
As the interceptors approached the object, they encountered significant system disruptions. Both jets lost critical instrumentation and communications when within several miles of the unknown craft. According to pilot reports, these malfunctions included temporary loss of radios and navigational systems—systems that returned to normal only when retreating from the object.
Major Jafari attempted to engage the target with an air-to-air missile. As he prepared to fire, the F-4’s fire-control panel and missile release systems went offline. This failure, occurring only while near the object, prevented any attempted weapons deployment.
Technical analysis suggested possible electromagnetic interference or jamming, though the exact cause remained unidentified. The event prompted the Iranian Air Force to report the incident through military channels, with attention from higher authorities concerned about threats to national security and the reliability of military technology during encounters with unidentified aerial phenomena.
Communications and Surveillance
Throughout the incident, communications between the Iranian interceptors and Mehrabad Air Base were severely hampered. Signals intelligence teams monitored radio traffic and detected periods of unexplained silence corresponding with proximity to the object. Ground-based radar at Mehrabad successfully tracked both the F-4 jets and the unknown target, noting that the latter violated expected flight patterns and altitudes.
Despite technical setbacks, the Iranian Air Force continued to relay incident data to national defense agencies. Reports were later shared with both domestic and international partners, including the U.S. military.
