A Russian An-124 ‘Ruslan,’ one of the world’s largest military cargo aircraft, reportedly landed secretly in Tehran on November 2, sparking intense speculation over a covert arms transfer to Iran. Open-source flight trackers and satellite imagery revealed unusual activity at Tehran’s Mehrabad Airport, with IRGC personnel guarding the plane amid fuel and cargo operations. Analysts believe the flight is linked to ongoing Russian airlifts delivering S-400 missile components and Su-35 fighter jets to Tehran under a secret deal. The aircraft reportedly departed from Russian cities known for defense production, reinforcing suspicions of a major weapons shipment. The alleged transfer coincides with Iran’s missile tests and escalating regional tensions, as Israel intensifies operations against Hezbollah in Lebanon. Western intelligence agencies warn that Moscow’s arms deliveries to Tehran could provoke new U.S. sanctions and further complicate Israel’s potential strike plans on Iran’s nuclear sites.
