Israel allegedly incapacitated Iran’s prized Russian-made S-300 air defense systems in a recent strike, potentially opening the door for further attacks on Iranian soil.
According to sources speaking to the Wall Street Journal, Israel’s recent strikes, executed on October 26, targeted three operational S-300 systems in Iran, effectively dismantling a key pillar of the country’s aerial defense.
This operation followed earlier strikes that had already eliminated Iran’s other S-300 units. The offensive, referred to as Operation Days of Repentance, showcased Israel’s capability to penetrate and disrupt Iran’s air defense network with minimal resistance.
Nearly 100 missiles were launched from Israeli fighter jets, and Iranian forces reportedly intercepted “few, if any,” of these, demonstrating the vulnerability of Tehran’s defense infrastructure.
The precision and effectiveness of these strikes underscore Israel’s extensive intelligence operations within Iran, a capability that has been demonstrated in previous high-profile attacks, including the assassination of Hamas’s political chief in Tehran in August and strikes targeting Iran’s nuclear program.
The Institute for the Study of War (ISW), a US-based think tank, corroborated these assessments, confirming that Israel struck three to four S-300 air defense sites, including one positioned at the strategically important Imam Khomeini International Airport.
ISW analysts further noted that some of these air defense sites were safeguarding critical energy assets in Iran’s western and southwestern regions.
Sites such as the Abadan oil refinery, Bandar Imam Khomeini energy complex and port, and the Tang-eh Bijar gas field reportedly came under attack. This highlights Israel’s focus on weakening Iran’s strategic infrastructure.
Experts view the attack as potentially preemptive, possibly setting the stage for future, broader offensives against Iranian assets, including nuclear sites.
Ali Vaez, Iran Director at the International Crisis Group, told NewYork Times, “This looks like a potential preamble to a much more effective strike against Iran’s infrastructure and even nuclear sites,” adding that Iran’s limited capability to promptly replace these defense systems leaves it considerably vulnerable to subsequent Israeli operations.
Beyond disabling air-defense systems, the recent strike also reportedly targeted key missile production facilities operated by the Iranian Revolutionary Guards Corps, including the Falagh, Shaid Ghadiri, and Abdol Fath bases.
Additionally, drones were used in attacks on Iran’s Parchin and Parand military sites. Both Israeli and Iranian officials confirmed these strikes.
Iran’s S-300 Air Defense System
With Iran’s primary air defenses reportedly compromised, Israel’s recent operation has carved out a strategic pathway for potential, more assertive airstrikes, presenting Tehran with increased security risks and an acute sense of vulnerability.
This development places Iran’s defenses at a crossroads, challenging its ability to shield its critical infrastructure and raising concerns about its capacity to deter future attacks.
Iran’s prized Russian-made S-300 air defense systems were intended to fortify its strategic sites and enhance its defensive posture. The acquisition journey began in 2007 when Tehran signed an $800 million contract with Moscow to procure these advanced defense systems.

However, the deal stalled in 2010 after the Kremlin froze the contract due to United Nations sanctions on Iran. Russian President Vladimir Putin finally approved the S-300 for delivery in 2015, shortly before Iran’s nuclear agreement with six global powers was finalized.
Tehran’s goal was to secure four S-300 systems, viewing them as essential to counterbalance the sophisticated American-made fighter jets and air defense systems of neighboring Gulf nations.
The advanced S-300 system, with its extensive tracking range and long-distance targeting capabilities, was widely anticipated to provide Iran with a formidable defensive advantage.
In 2015, Qatari media coverage underscored this, with Al Jazeera highlighting the system’s capacity to track and potentially intercept targets well beyond Iran’s borders. By 2016, Iran confirmed the arrival of its first S-300 system.
Each S-300 battery comprises a complex array of components, including multiple launchers and dual radar systems, providing layered defense capabilities. Tehran acquired the S-300PMU-2 model, one of the more advanced versions known to NATO as the SA-20B Gargoyle.
Since 2015, Iran has received four of these modernized systems from Russia. This variant, introduced in 1997, has enhanced anti-ballistic missile capabilities. However, these systems were not able to thwart the Israeli Air Force.
This could be due to the IAF’s extensive training and preparation, specifically aimed at countering advanced air defense systems like the S-300. Through participation in multinational exercises, the IAF has gained valuable insights and hands-on experience in engaging with S-300PMU-1 systems, particularly those operated by Greece.
Reports suggest that Iranian radar systems were “breached” during the recent airstrikes, causing their “screens to freeze.” This breach reportedly limited Iran’s capacity to intercept targets, allowing the Israeli Air Force (IAF) to penetrate Iranian airspace.
According to The Jerusalem Post, the strikes affected all of Iran’s air defenses, further compromising their operational effectiveness.
S-300 AD System Faces Scrutiny
Despite undergoing steady upgrades since its introduction by the Soviet Union in the late 1970s, the S-300 has shown increasing signs of obsolescence, particularly against more advanced aerial threats.
The S-300 system, once considered a powerful shield against aerial threats, has seen its limitations exposed in recent conflicts, leaving Tehran with diminished defensive capabilities and heightened susceptibility to future Israeli aerial operations.
Yet, in a notable incident in 2022, the S-300 made headlines when it launched a surface-to-air missile at departing Israeli F-16 fighter jets following their strike on Iranian positions near Syria’s Masyaf. However, the missile failed to bring down the aircraft.
The ongoing conflict in Ukraine has further exposed these weaknesses, as Ukrainian forces have successfully targeted and dismantled not only S-300 systems but also more sophisticated Russian S-400 systems.
The implications of these developments extend beyond battlefield performance. According to the Stockholm International Peace Research Institute (SIPRI), Russian arms exports have plummeted since the commencement of the large-scale invasion of Ukraine in 2022, with foreign weapon sales decreasing by 52% in the past year.
This drop suggests that Russian arms exports are likely to remain significantly below the levels achieved between 2014 and 2018 for the foreseeable future.
Nonetheless, the S-300 remains a key component within a layered defense framework, continuing to pose challenges for adversaries. In fact, US military personnel have previously encountered unanticipated modes of operation within these systems amid the Ukraine conflict.
In 2023, US Air Force 388th Fighter Wing Commander Colonel Craig Andrle noted that F-35 fighter jets sometimes struggled to identify the S-300 effectively, as reported by the EurAsian Times.
Despite intelligence indicating its presence, the F-35 stealth fighter jets failed to recognize it as an S-300 because it was operating in modes unfamiliar to US forces.
Andrle remarked, “We’re looking at a Sa-20 [NATO’s name for the S-300 surface-to-air missile system]. I know it’s a Sa-20. Intel says there’s a Sa-20 there, but now my jet doesn’t ID it as such because that Sa-20 is potentially operating in a war reserve mode that we haven’t seen before.”
