Iran is running out of excuses against accusations that they are supplying UAVs, cruise missiles and ballistic missiles to Iran-backed groups in Yemen, Iraq, Syria and Lebanon for attacks on Israel, Yemen and anyone who opposes Iranian aggression. These weapons are built with Iranian components that are deliberately made with key components lacking any visible evidence that they were manufactured in Iran. A lot of effort is put into this. But Iran sometimes uses the same unmarked components in weapons that are clearly labeled as Iranian.
Despite all those deception efforts UN and other investigators have been collecting components from debris of Iranian (labeled or unlabeled) UAVs and missiles that functioned properly and exploded as well as some that were captured or crashed near Iranian territory. The UN and Saudi Arabia have put many of these components on public display and the U.S. has also displayed captured Iranian arms shipments or missile components recovered from weapons that have crashed. One of the common items found in all these cases is an unmarked (no indication of manufacturer or national origin) gyroscopes. These miniature devices are common in all manner of UAVs and missiles. Gyroscopes of the type Iran is supplying are available on the commercial market but only the model Iran denies producing is showing up in systems, used by Islamic terrorists as well as systems that are clearly marked as Iranian. This was the result of Iran trying to save some money by not manufacturing a similar gyroscope clearly marked as Iranian for systems that are officially Iranian. A bit of false economy there because dozens of these gyroscopes have been collected from crashed or exploded systems. There is always debris, even when a system explodes and many small components, like these gyroscopes, survive intact. Iran denounces this evidence as an American conspiracy but no one except Iran and their allies are accepting this. A growing number of these Iran-backed groups are recognized by the UN and other organizations as international terrorists.
The gyroscopes have been collected in Yemen, Saudi Arabia, Israel and Afghanistan. One of the earliest examples was found in 2016 when an Iranian UAV crashed in Afghanistan and U.S. forces seized it and photographed/scrutinized the components. In later years the gyroscope kept showing up in other countries. The gyroscope is a unique design not available from any Western, Chinese or Russian manufacturer. It is of no identifiable (by markings) country but all the evidence points to Iran, especially since the mystery gyroscope shows up in UAVs that Iran proudly claims are Iranian made from Iranian components.
Some of these “unidentified” UAVs and missiles also contain other components that indicate Iranian origin even though the Iranians claim that they were produced locally by Iranian backed groups. That explanation falls apart when you look at pictures as the local product and the Iranian made model it is based on. Differences are often minimal. Some of these UAVs and missiles are built with some local materials like sheet metal but the design is clearly Iranian and key components, like the gyroscopes are not from any commercial supplier but smuggled in by Iran. The unmarked gyroscopes have one thing in common, they are found in “locally built” systems of Iran-backed groups.
The most telling evidence comes from Iranian arms shipments captured from the smugglers who are paid to get them into Yemen or Gaza. In addition to Iranian weapons clearly marked as Iranian made there are often quantities of Iranian components, including the mystery gyroscopes. Iran dismisses all this as an American or Israeli plot to defame Iran. Yet in Iran the Quds Force, a special section of the IRGC (Iranian Revolutionary Guard Corps) is praised for the extensive support it provides for Iran-backed rebel and terrorist forces throughout the region. It is no secret in Iran that Quds provides technical as well as tactical and organizational help to these groups carry out attack using rockets, ballistic missiles and cruise missiles. Israel has launched hundreds of airstrikes against Quds Force operations in Syria, Lebanon, Iraq and Gaza to halt Iranian shipments of these guided weapons or components, from reaching Hezbollah stockpiles of unguided rockets in Lebanon. Iran has developed upgrade kits that make these rockets much more accurate. Those upgrade kit shipments contain more of the mystery gyroscopes.
