Iran has said it used a new air defense system to shoot down a US MQ-9 Reaper drone near the Strait of Hormuz earlier this week, an incident that analysts say shows Tehran has retained its ability to repel US and Israeli attacks despite months of attacks on its military sites.
Iranian media said the drone was shot down near Qeshm Island in the Strait of Hormuz, adding that the interception marked the first combat use of a locally developed system called Arash-e Kamangir.

There has been no independent verification of Iran’s claim of a new interception system.
The United States’ loss of a drone near one of the world’s most sensitive shipping lanes comes as it reportedly carried out new strikes against an Iranian military site near Bandar Abbas. Iran’s Islamic Revolutionary Guard Corps (IRGC) later said it had attacked a “US air base” in retaliation.
As tensions between Iran and the United States continue to rise despite a fragile ceasefire, Tehran’s claim that it intercepted a US drone has renewed questions about how much of Iran’s air defense capability survived months of Israeli and US strikes, and whether Iran retains the resilience to withstand another round of strikes should negotiations fail.
What did Iran say?
Iran’s semi-official Fars news agency said the Arash-e Kamangir system was used to intercept a “hostile” reconnaissance drone over the Strait of Hormuz. He described the system as having stealth detection capabilities, but gave few technical details.
Iranian media said it was a warning to hostile aircraft operating near Iranian airspace and maritime borders, particularly at a time when Iran seeks to leverage its partial control of the strait in any ceasefire negotiations with the United States.
“This operation, which was carried out using a system with hidden capabilities, is a clear and decisive message from Iran,” Fars quoted anonymous officials as saying.
The new interceptor system announced by Fars translates, in Farsi, as “Arash the Archer,” and is named after the eponymous hero from Persian mythology who, as described in folklore, shot an arrow to trace the border between Iran and Central Asia. More generally, Arash is revered in poems and other literary works as a hero who helped Iran fight foreign domination.
How credible is Iran’s claim?
The claim should be treated with caution, analysts say. Iranian officials have a long history of publicizing military advances that are difficult to independently verify.
But experts also say the general idea behind the claim is plausible, as Iran is investing heavily in cheaper, mobile, domestically produced defense systems designed to threaten drones and aircraft without relying on large fixed radar sites that are easier to detect.
Mark Hilborne, a senior lecturer at the school of security studies at King’s College London, told Al Jazeera that while there was “very little independently verified information” about Arash-e Kamangir, the attack “would fit into a broader pattern”.
“Iran has become quite self-sufficient in various forms of missile design and, like Ukraine, has been smart about changing the economics of war. Cheap, simple systems can put much more complex systems at risk.”
The downing of the Reaper drone could also force the United States to rely more on expensive missiles than drones when attacking Iran.
Meanwhile, Tehran can continue to use Shahed drones, which are comparatively cheap to produce, which could give Tehran a long-term economic advantage in any protracted conflict.
What could be Arash-e Kamangir?
Analysts who spoke to Al Jazeera said the Arash-e Kamangir interception may be less a revolutionary new weapon than another step in Iran’s broader shift toward lower-cost, mobile air defense.
Alex Almeida, a security analyst at Horizon Engage, a New York-based strategic intelligence platform, told Al Jazeera that the system may be related to other Iranian short-range surface-to-air or loitering weapons.
“I suspect it’s a later development of one of those systems,” he said. “It’s not relying on fixed guidance from a traditional air defense radar site. It’s probably using some form of electro-optical or heat-seeking guidance, essentially a pop-up SAM system. [surface-to-air missile] system that is easy to configure and run.”
This is important because traditional air defense networks rely on radars and launch batteries that are much easier to identify, while cheaper, smaller systems can be moved, hidden, launched quickly, and replaced more easily.
Some of these systems are designed so that the interceptor can wait in the air, circling a patch of sky until a target drone or plane appears. Others are short-range anti-drone or anti-aircraft weapons, which are cheaper and less sophisticated than main air defense batteries, but also easier to manufacture and replace.
That makes drones like the MQ-9 Reaper, designed to move slowly because their primary purpose is surveillance, particularly vulnerable.
Nicole Grajewski, an assistant professor at Sciences Po University in Paris, said Tehran may still need stronger medium- and long-range air defenses, but added that mobile systems have a clear benefit.
“The value is that you can move them quickly,” he said. “They are mobile launch systems, in some cases portable. We don’t know how high the Reaper was flying. Based on the video released, it may have been relatively easy for them to shoot it down, but it still indicates that they retain some remaining air defense capability.”
Why does this matter?
Iran’s largest air defense network has been severely damaged. It was built around older radar-guided surface-to-air missile systems, including domestically produced batteries and Russian-supplied missile defense systems such as the S-300. Israeli and American attacks are widely believed to have degraded much of that network.
But the new interception system suggests that Iran still appears to retain systems that enable a “persistent, limited, low-level air threat” that is difficult to permanently suppress, Almeida said.
These systems may not be able to stop a major air campaign or shoot down advanced aircraft in significant numbers, but they may force the United States and Israel to rely more on expensive standoff weapons launched from further away.
Grajewski said Iran’s military strategy is based on resilience rather than technological parity.
“Its systems are not particularly sophisticated or fully integrated, but as a result, Iran’s military strategy focuses heavily on resilience, resistance and mobility,” he said.
That resilience also has strategic consequences. If the United States or Israel cannot permanently eliminate Iran’s ability to retaliate, each new attack carries the risk of another round of escalation in the Gulf, or further disruption along the Strait of Hormuz and sending US gas prices soaring.
“I wouldn’t say Iran is as worried as the United States and Israel,” Grajewski said.
“I think the United States exaggerated and exaggerated the success of these operations… and Israel and the United States have ammunition limitations.
“Iran has an important defense industry and, after the 12-day war [in June 2025]managed to increase the production of ballistic missiles to high levels by international standards. “Iran also retains an asymmetric advantage, and in some ways the United States and Israel are more constrained than Iran,” he added.
He said Iran’s approach to air defense was less about maintaining a sophisticated integrated network and more about building systems designed around “resilience, endurance and mobility.”
“One problem with Western discussions of Iran’s missile performance is that analysts often judge them by Western doctrines and expectations, saying they are inaccurate or ineffective. But from Iran’s perspective, operating against a far superior adversary, I would argue that they actually exceeded their own expectations.”
