On February 28, 2026, American and Israeli warplanes obliterated billions of dollars worth of Russian-made weapons systems sitting on Iranian soil — including every single S-300 long-range air defense battery Iran had spent nearly two decades trying to acquire from Moscow. The joint operation, dubbed “Roaring Lion” by Israel and “Operation Epic Fury” by the Pentagon, didn’t just knock out Iran’s nuclear ambitions and kill Supreme Leader Ali Khamenei. It systematically dismantled the very Russian hardware that was supposed to make Iran untouchable from the air, leaving the country, as one defense official put it, “essentially naked” in terms of long-range air defense. The irony runs deep. Iran had poured roughly $4 billion in arms into Russia’s war machine since 2021, including $2.7 billion in missiles and thousands of Shahed kamikaze drones that terrorized Ukrainian cities.
In return, Moscow sold Tehran its flagship S-300 systems, Mi-28 attack helicopters, Yak-130 training jets, and armored vehicles. When the bombs started falling, Russia offered nothing but a sternly worded condemnation calling it a “preplanned and unprovoked act of armed aggression.” No military support. No emergency resupply. Not even a credible diplomatic intervention. This article breaks down the full scope of what Russia sold Iran, how those weapons performed (or failed to perform) under fire, what the destruction means for the Russia-Iran relationship, and what comes next for a regime scrambling to rebuild its defenses from scratch.

What Russian Weapons Did Iran Buy, and How Were They Destroyed by American and Israeli Bombs?
The centerpiece of the Russian-iranian arms relationship was the S-300 long-range surface-to-air missile system. Iran originally contracted to buy the S-300 back in 2007, but delivery was repeatedly blocked by international sanctions. The systems finally arrived around 2016, and Iran deployed multiple batteries around Tehran and critical nuclear and military installations. These were not cheap parade props — the S-300 is a genuinely capable system with a proven track record in other theaters. Iran treated them as the backbone of its national air defense, the one system that was supposed to deter or at least complicate any American or Israeli air campaign. Beyond the S-300s, Russia supplied Iran with up to six Mi-28 attack helicopters delivered in January 2026, at least one squadron of Yak-130 combat training aircraft delivered in 2024, and Spartak armored vehicles. Moscow had also agreed to supply up to 48 Su-35 fourth-generation-plus fighter jets, though as of early 2026, none had been confirmed as operationally delivered.
There was also a freshly signed €500 million contract for Verba man-portable air defense systems (MANPADS), inked in December 2025 after Iran’s devastating experience in the 12-Day War made clear that its existing defenses had critical gaps. The timing of that contract — just weeks before the February strikes — underscores how urgently Tehran knew it was vulnerable. When the strikes came, none of it mattered. Israeli and American forces systematically targeted and destroyed all of Iran’s S-300 batteries across the combined October 2024 and February 2026 strike campaigns. Post-strike satellite imagery showed a conspicuous absence of S-300 fire-control radars at known deployment sites, indicating not just damage but total elimination of operational capability. Radar sets used to guide ballistic missiles were also destroyed. The weapons Russia sold as a strategic deterrent lasted roughly a decade before being reduced to scrap metal in a matter of hours.
Why Did Russia’s S-300 Air Defense Systems Fail to Protect Iran?
The failure of the S-300 in Iranian hands needs to be understood in context. The S-300 is not an invincible system — no air defense system is. It was designed during the Cold War era to defend against high-altitude bomber formations, and while modernized variants can engage cruise missiles and some ballistic threats, the system has well-documented vulnerabilities against coordinated, multi-axis saturation attacks using stealth aircraft, electronic warfare, and precision standoff munitions. Israel had already demonstrated in October 2024 that it could penetrate Iranian air defenses, reportedly knocking out several S-300 batteries in that earlier round of strikes. By February 2026, the Iranians were attempting to reconstitute coverage, but the combined American and Israeli force brought overwhelming capability to bear. However, it would be a mistake to conclude that the S-300 is simply a bad system.
In the hands of a more technologically sophisticated operator with better integration, training, electronic warfare support, and redundancy, the S-300 family has performed more credibly. The critical limitation for Iran was that it was operating these systems in relative isolation — without the kind of layered, networked air defense architecture that Russia itself maintains domestically. Iran also lacked the satellite early-warning systems, advanced electronic countermeasures, and airborne command-and-control assets that would give the S-300 batteries enough warning and situational awareness to be effective against a first-world adversary. Russia sold Iran the hardware but not the full ecosystem required to make it work against the United States Air Force and the Israeli Air Force operating in concert. There is also the question of whether Russia provided Iran with degraded export variants. This is common practice in the arms trade — countries routinely sell less capable versions of their systems to foreign buyers, withholding the most advanced software, radar modes, or electronic countermeasure capabilities for their own forces. If the S-300 batteries Iran operated were running older software or lacked certain classified capabilities, they would have been significantly more vulnerable to the jamming and suppression tactics American and Israeli forces are known to employ.
The $4 Billion Arms Deal That Bought Iran Nothing When It Mattered
The lopsidedness of the Russia-Iran arms relationship became impossible to ignore on February 28. According to Bloomberg reporting, Iran had supplied Russia with approximately $4 billion worth of weapons since 2021 to support Moscow’s invasion of Ukraine. Of that total, $2.7 billion consisted of missiles alone. Add thousands of Shahed one-way attack drones that became a defining feature of the war in Ukraine — cheap, mass-produced, and devastatingly effective against Ukrainian infrastructure — and Iran had effectively become one of Russia’s most important wartime suppliers. In return, when American B-2 bombers and Israeli F-35s were tearing through Iranian airspace, Russia’s response was a statement from the Foreign Ministry calling the strikes a “preplanned and unprovoked act of armed aggression.” That was it. No emergency airlift of replacement air defense systems. No threat of retaliation.
No activation of any mutual defense understanding. The contrast with Iran’s material support for Russia could not have been starker. Tehran had put real, tangible, war-winning hardware into Russian hands for years, and Moscow repaid that investment with a press release. This dynamic matters for understanding the geopolitical landscape going forward. Iran learned an expensive lesson about the difference between a transactional arms supplier and a genuine military ally. Russia was happy to take Iranian drones and missiles for its own war, and happy to sell Iran weapons systems at market prices, but had zero interest in absorbing the strategic risk of confronting the United States or Israel on Iran’s behalf. For observers of international arms markets and alliance politics, this is a case study in what happens when a buyer mistakes a vendor for a partner.
How Do the February 2026 Strikes Compare to Israel’s October 2024 Attack on Iran?
The October 2024 Israeli strikes on Iran were significant but limited in scope. Israel targeted specific S-300 battery positions and radar installations, demonstrating that it could penetrate Iranian air defenses and destroy high-value targets. The operation was calibrated — designed to send a message and degrade capability without triggering a full-scale regional war. Several S-300 batteries were destroyed, and radar sets used for ballistic missile guidance were knocked out. But Iran’s overall military infrastructure, nuclear program, and political leadership survived intact. The February 2026 operation was a different animal entirely.
Conducted jointly by the United States and Israel as part of the broader 12-Day War, it targeted not just air defense systems but nuclear facilities, missile production plants, and key regime figures — including Supreme Leader Ali Khamenei himself, who was killed in the strikes. The operation names alone — “Roaring Lion” and “Operation Epic Fury” — signaled a level of ambition and coordination far beyond anything previously attempted. Every remaining S-300 battery was destroyed, completing the work started in October 2024 and leaving Iran with no long-range air defense coverage whatsoever. The tradeoff inherent in the two approaches is instructive. The 2024 strikes were proportional and deniable enough to avoid a wider war, but they left Iran capable of rebuilding and reconstituting its defenses. The 2026 strikes were comprehensive but carried enormous escalation risks, fundamentally altered the political map of the Middle East, and left the United States and Israel with long-term responsibilities they are still sorting out. Whether the more aggressive approach was justified depends on your assessment of the Iranian nuclear threat, but there is no question that it achieved a more decisive military outcome.
Iran’s Scramble to Rebuild Air Defenses After Total System Failure
In the aftermath of the February strikes, Iran found itself in a position no major regional power wants to occupy: completely without long-range air defense. The country’s attempts to rebuild have been urgent but constrained. The €500 million Verba MANPADS contract with Russia — signed in December 2025, before the February strikes — represents one line of effort, but MANPADS are short-range, man-portable systems designed to engage low-flying aircraft and helicopters. They are not a substitute for the S-300’s ability to threaten aircraft at distances of over 100 kilometers and altitudes above 80,000 feet. Replacing the S-300 with MANPADS is like replacing a hospital’s surgery department with a first-aid kit. Iran has signaled interest in reconstituting a layered air defense grid that combines whatever Russian systems it can acquire with partially indigenous systems.
But there are serious limitations to this approach. Developing credible long-range air defense systems domestically requires decades of investment in radar technology, missile guidance systems, command-and-control software, and integration testing. Iran has made progress on shorter-range indigenous systems like the Bavar-373, which Tehran has claimed is comparable to the S-300, but those claims have never been validated in combat against a peer adversary — and the Bavar-373 batteries appear to have been no more effective than the Russian systems during the strikes. The deeper warning here is about supply chain dependency. Iran built its entire strategic air defense posture around a single foreign supplier whose interests were not aligned with Iran’s survival. When that supplier declined to intervene or resupply under fire, the entire edifice collapsed. Any country watching this situation — and many are — should be asking hard questions about what happens to their own defense when the vendor decides the relationship is no longer worth the risk.
What the Russia-Iran Arms Collapse Means for the Global Weapons Market
The destruction of Russian arms in Iran has implications well beyond the Middle East. Russia is one of the world’s largest arms exporters, with customers across Africa, Asia, and Latin America. Many of those customers bought Russian systems precisely because they were marketed as capable of countering American and Israeli military technology. The spectacular failure of the S-300 in Iranian service — not once but twice, in 2024 and 2026 — is the most visible real-world stress test of that sales pitch, and it failed.
Countries currently operating or considering purchasing Russian air defense systems, including the more advanced S-400, are watching closely. India, Turkey, Algeria, and others have significant Russian air defense inventories and must now recalculate the actual combat value of those investments. For Russia’s defense industry, already strained by the demands of the Ukraine war and Western sanctions on components and technology, the reputational damage compounds an already difficult commercial environment. Selling weapons that get destroyed on television by your customer’s adversaries is not a strong marketing position.
Where Does the Russia-Iran Relationship Go From Here?
The February 2026 strikes exposed a fundamental asymmetry in the Russia-Iran partnership that will be difficult to paper over. Iran invested billions in Russia’s war effort and received, at the decisive moment, nothing in return. Russia’s verbal condemnation of the strikes was so pro forma that it likely deepened Iranian resentment rather than smoothing it over. The question now is whether Tehran continues to supply Moscow with drones and missiles for the Ukraine war, or whether the relationship enters a more transactional, trust-deficient phase.
Early indicators suggest Iran is hedging. The Verba MANPADS contract proceeds, suggesting Tehran has no immediate alternative supplier for air defense systems, but Iranian officials have reportedly been exploring options with China and even reconsidering the pace of indigenous defense development. For Russia, losing Iran as a reliable arms customer and drone supplier would be a serious strategic setback — one more consequence of a war in Ukraine that has steadily eroded Moscow’s global position. The weapons that were supposed to cement a strategic partnership instead became a symbol of its hollowness.
Conclusion
The destruction of Russian-made weapons systems in Iran during the February 2026 strikes is one of the most consequential military and geopolitical events in recent years. Every S-300 battery Iran spent nearly two decades acquiring was wiped out. The Mi-28 helicopters, the radar systems, the air defense infrastructure — all of it proved unable to withstand a coordinated American and Israeli assault. And the country that sold Iran those weapons, which had received $4 billion in Iranian arms for its own war, offered nothing but words when the bombs fell.
The lessons are stark and applicable far beyond the Middle East. Military alliances built on arms sales alone are not alliances at all. Air defense systems sold without the supporting ecosystem of training, electronic warfare, early warning, and network integration are expensive targets, not deterrents. And any nation that builds its security around a single foreign supplier’s hardware is one bad day away from finding itself, as the defense officials described Iran, essentially naked. The Russian weapons Iran bought are now debris fields, and the relationship that produced them may not be far behind.
