Iran Enhances Drone and Missile Precision
On Monday, Iran revealed it is now using guidance chips sourced from China and Russia to boost the accuracy of its drone and missile attacks. This change aims to enhance the performance of Iran’s Shahed drones and ballistic missiles.
“These chips are pivotal,” experts noted, as they enable advanced navigation systems aboard these weapons. They will allow for better communication even under electronic jamming, specifically through a technology known as Controlled Reception Pattern Antenna (CRPA).
The CRPA antennas can swiftly switch between different frequencies to evade jamming attempts. This technology, alongside updated navigation software, empowers drones and missiles to function in complex electronic warfare settings where traditional systems might struggle.
However, for CRPA to work effectively, the drones must have advanced electronics capable of processing signals from multiple antennas and adjusting to any disruption in real time.
Reports suggest that Iran has recently acquired these sophisticated chips from Russian and Chinese allies, which are expected to significantly improve its weaponry, making them far more effective than previously deployed systems. There might also be targeted support from Russian satellites and ground stations aiding these advancements.
According to a Western official, “CRPA enables drones and missiles to filter out jamming signals, obtaining actual satellite data, which is crucial for navigating through heavily defended airspaces. This level of capability was once exclusive to more advanced military forces.”
Some analysts indicate a significant exchange of technology between Iran and Russia. Initially, Iran provided Russia with a surplus of low-cost Shahid drones to enhance its efforts against Ukraine; in return, Russia developed improved versions and sent some back to Iran.
Bredin Bowen, an astrophysics professor at Durham University, speculated that China may also be assisting Iran by granting access to the Beidou Navigation Satellite System (BDS), which is more precise compared to Russia’s Glonass system.
Bowen highlighted that advancements in surveillance technologies from Russia and China could greatly enhance Iran’s battle damage assessments, an area that has historically posed challenges. These improvements would enable Iran to refine its weapon accuracy and assess the necessity of further strikes.
During Operation Epic Fury, Iran launched over 4,550 Shahed drones targeting U.S. military bases and infrastructure in neighboring Gulf states, demonstrating a notable increase in effectiveness compared to earlier attacks.
In a particularly concerning incident, Iran successfully targeted an American surveillance and refueling aircraft at Saudi Arabia’s Prince Sultan Air Base using a coordinated swarm of around 30 Shahed drones and six ballistic missiles.
A recent NBC News report indicated that the damage inflicted on U.S. military bases in the Middle East by these attacks was “significantly worse than initially reported” and could amount to billions in repair costs, as stated by several U.S. officials and congressional aides.
The report detailed how Iran targeted various military installations across seven countries, causing extensive damage. Notably, aging Iranian F-5 fighter jets managed to breach multiple levels of U.S. air defenses, launching low-altitude bombing runs on Camp Buehring in Kuwait.
If these assessments hold true, it might suggest that Iranian drones and missiles have greatly improved in accuracy since 2024, effectively overcoming some electronic warfare defenses.
