On October 25 and 26, 2024, tensions between Israel and Iran escalated as Israel launched a series of airstrikes targeting Iranian military sites. This aggressive response followed Tehran’s large-scale missile attack involving over 200 ballistic missiles aimed at Israeli territory.
However, the limited impact of Israel’s strikes raised questions, particularly about the role advanced air defense systems or external interference might have played. Who jammed the F-35 over Iran remains the unanswered question. The S-300 or the Pentagon?

Israel’s Strategic Airstrikes
The Israeli airstrikes targeted Iran’s missile systems, command centers, and critical infrastructure, aiming to curb Iran’s military advancements. Using about 100 advanced fighter jets, including the F-35 Adir, Israel planned to deal a severe blow to Iran’s defenses. Yet, contrary to expectations, the damage was minimal.
This outcome has led analysts to speculate about various factors, including pressure from the United States to avoid further escalation ahead of the U.S. presidential elections on November 5.
Despite this political dimension, military experts suggest Iran’s advanced air defense systems, particularly the Russian-made S-300 and domestically produced Bavar-373, played a decisive role. Could these systems explain who jammed the F-35 over Iran? Could it have been the S-300 or the Pentagon?
Iran’s Advanced Air Defense Systems
Iran boasts an array of formidable air defense capabilities, including the S-300, Bavar-373, and upgraded S-200 variants. These systems are designed to detect and neutralize stealth aircraft like the F-35 at considerable distances.
- S-300: The Russian-made S-300 excels in tracking stealth aircraft and engaging targets across large airspaces. While F-35s utilize stealth technology to minimize detection, the S-300’s advanced radar systems challenge these capabilities.
- Bavar-373: Iran’s indigenous Bavar-373, inspired by the S-300, is tailored to counter high-maneuverability targets like the F-35. Its enhanced detection range and precision make it a cornerstone of Iran’s air defense network.
The effectiveness of these systems might explain who jammed the F-35 over Iran. Could it have been the S-300 or the Pentagon?
How Iranian Defenses Countered the F-35
Reports suggest that Iranian radars detected Israeli F-35s while they were still in Iraqi airspace, far from Iranian borders. This unexpected capability forced Israeli pilots to release their air-launched ballistic missiles (ALBM) prematurely. The early launch reduced the effectiveness of the strikes, as the missiles failed to reach their optimal positions for neutralizing Iranian defenses.
For the first time, Iranian or Russian air defense systems reportedly locked onto Israeli F-35s, showcasing their ability to challenge Israeli air superiority. This incident brought the question to the forefront: Who jammed the F-35 over Iran? The S-300 or the Pentagon?

Russia’s Role in Enhancing Iranian Defenses
In April 2024, Russia and Iran reportedly mapped out Israel’s air defense systems, bolstering Tehran’s preparedness. Russia has also allegedly supplied Iran with the advanced S-400 system, known for its exceptional ability to track stealth aircraft over long distances.
Although the S-400 may not have been operational during the October strikes, its impending integration into Iran’s defense network signals a shift in the regional military balance. Whether the S-300, the S-400, or another system played a role remains a crucial part of the debate about who jammed the F-35 over Iran. Could it have been the S-300 or the Pentagon?
External Interference: The Pentagon’s Role?
While Iran’s air defense capabilities are impressive, some analysts argue that the limited success of Israeli strikes may also involve electronic warfare interference from the Pentagon. The U.S., keen on avoiding further escalation, might have shared intelligence or employed electronic jamming measures to restrain Israel’s operation.
This possibility presents an intriguing angle: Was it the S-300, or did the Pentagon have a covert role in jamming the F-35 over Iran?
Implications for Regional Air Dominance
The October strikes highlighted a pivotal shift in the Middle East’s air combat landscape. Israeli air superiority, long considered unmatched, now faces significant challenges. Iran’s growing sophistication in air defense, backed by Russian technology, presents a formidable obstacle.
To maintain its strategic edge, Israel must reassess its tactics and invest in countermeasures against systems like the S-300, Bavar-373, and potentially the S-400. This evolving dynamic points out the importance of answering who jammed the F-35 over Iran. The S-300 or the Pentagon?

The Path Forward
The October confrontation has sparked renewed discussions about regional military strategies and the role of advanced technology in modern warfare. The ability of Iran’s defenses to counter Israeli strikes signifies a paradigm shift, challenging assumptions about stealth aircraft invulnerability.
Additionally, the possible involvement of the Pentagon in tempering Israel’s operations reflects the complicated relationship between international politics and military engagements. As the dust settles, one question remains central to future military planning: Who jammed the F-35 over Iran? The S-300 or the Pentagon?
Conclusion
The October airstrikes on Iran mark a critical moment in the evolving conflict between Israel and Iran. Whether Iran’s air defense systems, such as the S-300 or Bavar-373, were solely responsible for jamming the F-35, or whether external forces like the Pentagon influenced the outcome, remains a subject of intense debate.
The incident highlights the growing difficulties in sustaining air superiority in a region where technological advancements are creating equal opportunities. Moving forward, who understands who jammed the F-35 over Iran? The S-300 or the Pentagon will be essential for shaping military strategies and maintaining balance in the Middle East.
