A Test of Advanced Air Defenses
In a dramatic escalation, Iranian air defense successfully intercepted missiles launched by Israel on October 26, hours after an Israeli missile strike targeting Tehran. The strikes highlighted Iran’s missile defense systems, showcasing the nation’s readiness and capabilities in the face of regional tensions. Russia, having alerted Iran of the impending strike, also underscored its role as a regional ally committed to maintaining stability. The events left Iran evaluating its defensive response, particularly concerning the long-range air-launched missile threat posed by Israel.

Israel’s Long-Range Missile Attack Strategy
Israel’s approach involved launching missiles from aircraft positioned safely outside Iranian airspace, minimising risks to its personnel and equipment. The air operation targeted Iran’s air defense systems, missile facilities, and military infrastructure, avoiding nuclear and oil assets. This strategy echoes Israel’s past tactics against Syrian targets and reflects broader efforts to disrupt adversaries’ air defense capabilities without risking direct aerial confrontations.
Iran’s ground-based air defences faced formidable challenges. However, reports suggest that Iran intercepted most of the incoming threats, significantly weakening the impact of Israel’s strategy.
Russia’s Strategic Warning to Iran
Russia’s proactive stance in warning Iran of the missile attacks highlights a strengthening alliance, likely intended to deter Israeli aggression. Its role is significant, considering Iran’s reliance on Russian missile technology and intelligence for its air defense systems. With damage reportedly sustained in Tehran, Khuzestan, and Ilam provinces, the intercepted attacks underline Russia’s influential presence in Iran’s regional defense strategy.
Iran Air Defense Systems: Multi-Layered and Strategic
Iran employs a multi-layered defense network to counter threats from Israel and other regional powers. Key systems include:
1. S-300PMU-2: Backbone of Iranian Defense
- Background: Russia’s S-300PMU-2 forms the foundation of Iran’s long-range defense and is central to its interception capabilities.
- Range & Capabilities: Equipped with 48N6E2 missiles (200 km range) and possibly the 48N6DM variant (250 km range), these systems target hypersonic and supersonic threats.
- Strategic Positioning: Although advanced, the S-300PMU-2 remains vulnerable to fast-moving missiles, such as those launched by Israel, testing the effectiveness of Russian-origin technology against modern missile threats.
2. Bavar-373: Iran’s Indigenous Alternative
- Capabilities & Development: Developed domestically, the Bavar-373 aims to complement and potentially replace older Russian systems. Its Sayyad-4B missile can intercept threats up to 300 km away, marking an essential improvement in Iran’s defensive range.
- Impact on Defense Strategy: Iran’s commitment to Bavar-373 reflects a gradual shift from Russian reliance, with indigenous solutions intended to enhance response times and counter highly mobile threats.
3. Soviet-Era S-200D Systems
- Historical Use & Purpose: The S-200D’s role has evolved since the 1990s, with its long-range focus primarily on large targets like ballistic missiles.
- Operational Limitations: Despite recent upgrades, the S-200D’s tracking and targeting capabilities for smaller aerial threats remain limited, and it heavily depends on external radar support.
Iran’s multi-layered system integrates Russian, Soviet, and domestic technologies, reinforcing a network that can adjust to varying threat levels. This network presents a considerable challenge for Israeli and allied forces attempting air or missile strikes on Iranian territory.
Israel’s Attack Signals Escalating Regional Tensions
Hours before Israel’s missile strike, diplomatic channels were active. Israel warned Iran via intermediaries to prevent escalation and avoid civilian casualties, indicating that its primary targets were military. International responses included calls from Dutch officials urging de-escalation and an American advisory suggesting restraint. These diplomatic overtures reflect the high stakes involved, as any further escalation could lead to broader international involvement, particularly with the United States affirming support for Israel’s defense.
Israel’s recent actions and its choice not to target nuclear and oil facilities show that it wants to keep military responses limited, aiming for strategic deterrence instead of a major war.
Iranian Interception Response: S-300 and Bavar-373 In Action
Iran’s interception efforts during the Israeli attack brought its upgraded S-300 and Bavar-373 systems to the forefront. The successful intercept of many missiles demonstrates the integration of radar networks with long-range missiles designed to neutralise distant threats. Al Jazeera footage from Tehran’s night skies suggests Iranian air defences responded effectively, with mid-air explosions interpreted as successful missile interceptions.
These defences underscore Iran’s reliance on ground-based strategic systems rather than aerial counterattacks. The integration of Iran’s radar and missile systems ensures detection and interception of incoming threats from considerable distances, with the S-300PMU-2 and Bavar-373 being critical in the nation’s air defense strategy.
U.S. Warnings and Israel’s Military History with Long-Range Strikes
The United States urged Iran to limit its aggressive stance, with warnings that American support for Israel could intensify if hostilities increase. This aligns with Israel’s history of long-range missile use, reminiscent of operations in Syria, where Israeli airstrikes launched ballistic missiles that targeted adversarial defences.
Israel’s Past Military Actions:
- Syrian Operations: In 2018, a Syrian S-200 missile downed an Israeli F-16I, exposing vulnerabilities in Israel’s regional strikes.
- Potential for Enhanced Tactics: Leaked intelligence suggests that Israel might consider deploying advanced, long-range air-launched missiles against Iranian assets. This development reflects Israel’s need to stay ahead of improvements in regional defences.
Iran’s response to Israel’s tactics showcases the country’s preparedness to use medium- and long-range surface-to-air missiles [SAMs], which present a versatile defense option that can be adjusted to evolving threats.
S-300PMU-2: Iran Air Defense Foundation
Since its introduction in 2016, the S-300PMU-2 has remained Iran’s primary air defense system. The system combines various missile types for layered interception capabilities, including short-, medium-, and long-range targeting. The system’s ability to coordinate with other Iranian air defences enhances its effectiveness, particularly against Israel’s airborne missiles.
One notable element of Israel’s recent attack targeted a base near Tehran housing the S-300PMU-2. Whether Iran’s systems were equipped with advanced 48N6DM missiles remains unclear; however, these missiles have shown exceptional performance against high-speed threats, reaching speeds beyond Mach 8. Some speculate that Iran acquired this advanced variant, though the claim is unconfirmed.

Performance Insights:
- Anti-Missile Capabilities: The 48N6DM missile’s Mach 14 speed provides a strategic advantage over most aerial threats, with a range of 250 km.
- Reliability and Networking: Iran’s S-300PMU-2 units network with various defense systems, such as the Tor-M1 and Khordad 15, for improved layered defense.
Iran’s Indigenous Developments as a Response to Russian Withdrawal
