Following the initiation of a full scale U.S. and Israeli army assault in opposition to Iran on February 28, the capabilities of Iran’s ground-based surface-to-air missile community, alongside its drone forces and ballistic missile arsenal, have posed a major problem to Western and allied efforts to realize their goal of asserting army dominance and topping the nation’s authorities. Though little is understood relating to the capabilities of Iran’s indigenous air defence methods, together with the Bavar 373 and Khordad 15 lengthy vary methods which kind the spine of its defensive community, the Russian S-300PMU-2 has additionally been deployed to guard the capital Tehran, and is a system which Israeli, U.S. and different NATO member states’ forces have ready for years to have the ability to interact and destroy.
The US and different NATO members gained in depth entry to early variants of the S-300 system following the disintegration of the Warsaw Pact, with these then innovative methods having been extensively deployed by Warsaw Pact member in Jap Europe which had been absorbed into NATO, and extremely keen to switch them for examine. Ukraine inherited a very giant S-300 arsenal, and is extensively reported to have despatched S-300PS or S-300PT methods to the USA for examine. Nonetheless, these Soviet period S-300s had been way more constrained of their capabilities than then S-300PM household of methods, the primary of which entered service in 1992, that means they weren’t fielded by Warsaw Pact members. Regardless of this, Israel and a number of NATO member states gained entry to newer S-300 variants and educated extensively in opposition to them in simulated engagements.
Following the sale of S-300PMU-1 methods to Cyprus, which had been shortly obtained by Greece, the Greek Armed Forces supplied NATO allies and Israel with in depth alternatives to fly simulated assault missions in opposition to targets protected by the methods. These familiarised NATO and Israeli forces with the radar wavebands by which the S-300PM system operated, whereas offering alternatives to check digital warfare methods and different techniques in opposition to them. Greece additionally supplies coaching entry to the S-300 website for officers from NATO member states and from Israel. Greek S-300s have additionally at occasions fired missiles throughout workouts, offering alternatives to carry out reside fireplace evaluations of the missile’s engagement envelopes. In parallel to this cooperation, U.S. and Israeli delegations have visited Ukraine on a number of events to study in regards to the S-300’s capabilities and operational procedures, together with its radar modes, command-and-control procedures, and vulnerabilities.
The Iranian S-300PMU-2 is carefully associated to the Greek S-300PMU-1, though having been produced twenty years later, and benefitted from important customisation, its diploma of vulnerability to digital warfare methods and different measures developed throughout simulated engagements with Greek methods stays unsure. It’s extremely doable that avoiding vulnerabilities to intelligence which adversaries gained by Greek methods was a selected consideration when customisation was requested. Past coaching with Greek methods, nevertheless, the U.S. Air Drive has notably additionally carried out a number of operations to gather digital intelligence on newer variants of the S-300 system throughout the Russian-Ukrainian Battle.
The U.S. Air Drive from early 2022 deployed F-35A fighters to fly close to the Ukrainian theatre for alerts intelligence operations, with Russian air defence methods, together with newer S-300 variants, being major targets. Concerning operations in Jap Europe 388th Fighter Wing Commander Colonel Craig Andrle elaborated in an interview relating to how these operations supplied new data on the methods’ capabilities: “the jet is all the time sensing, gathering data. And it was doing that very, very properly… We’re taking a look at an SA-20. I do know it’s an SA-20. Intel says there’s an SA-20 there, however now my jet doesn’t ID it as such, as a result of that SA-20 is working, doubtlessly, in a conflict reserve mode that we haven’t seen earlier than.” The SA-20 is a NATO reporting identify for the S-300PMU-1 and PMU-2 variants.
The worth of having the ability to sort out S-300PMU-2 system far exceeds their utility in opposition to Iran, with the methods additionally deployed by Vietnam, China, Russia and Algeria, all of that are potential targets for future Western Bloc assaults, whereas the North Korean Pyongae-5 system is although to have been developed with in depth expertise transfers from the S-300PMU-1 program. Highlighting the significance o having the ability to sort out the methods, the U.S. Marine Corps in November 2025 used full scale mockups of air defence methods carefully resembling theS-300 within the Resolute Hunter 26-1 train at Naval Air Station Fallon, indicating that the drills had been supposed to simulate engagements with the methods. Though the operational effectiveness of Iran’s S-300 methods had been anticipated to be enhanced appreciable in 2026, with the supply of the primary Su-35 fighters to the nation permitting the plane to offer focusing on information and strengthen situational consciousness, the initiation of assaults earlier than these had been delivered dominated out this risk.
