History Made Over Tehran: Israel's F-35 Scores the World's First Stealth Fighter Combat Kill

It happened over the skies of Tehran on the morning of Wednesday, March 4, 2026 — Day 5 of Operation Epic Fury. An Israeli Air Force F-35I Adir fighter jet intercepted and destroyed a Russian-made Iranian Yak-130 combat aircraft in the airspace above the Iranian capital. In doing so, it made history twice over: it became the first F-35 in the world to shoot down a manned aircraft in combat, and it marked Israel's first air-to-air engagement involving manned aircraft in nearly four decades. What Happened The Israeli Defence Forces confirmed the engagement in a statement, announcing that an IAF F-35I Adir shot down an Iranian Air Force Yak-130 over Tehran. The IDF described the engagement as the first shootdown in history of a manned fighter aircraft by an F-35. The kill came during the tenth wave of Israeli airstrikes on Tehran — a wave the IDF described as extensive, involving dozens to hundreds of aircraft operating with varying mission packages alongside two standing objectives: neutralising ballistic missile threats and suppressing Iranian air defence systems. Iran had deployed its Yak-130 aircraft on air patrol missions over Tehran in the days prior to the engagement. The jets — armed with short-range air-to-air missiles — were assigned missions focused on identifying and intercepting aerial threats, including Israeli drones operating at medium and low altitudes. They were also observed operating alongside MiG-29 interceptors on flights designed to counter Israeli incursions into Iranian airspace. That deployment ultimately proved fatal for one of those aircraft on Wednesday morning. The F-35I Adir: Israel's Most Capable Fighter The F-35I Adir is Israel's customised variant of Lockheed Martin's F-35A stealth multirole fighter — modified with Israeli-specific avionics, electronic warfare systems, and weapons integration developed by Israel's defence industry. The Adir entered service with the Israeli Air Force in 2017 and has been used extensively in strike operations across the Middle East since then. Prior to Wednesday, F-35s operated by various air forces around the world had been used to shoot down unmanned aerial systems — most recently, the British Royal Air Force confirmed its own F-35B shot down uncrewed aerial systems over Jordanian airspace just one day earlier. But no F-35 had ever downed a manned, piloted aircraft in combat. Until now. The Yak-130: Russia's Jet in Iranian Hands The Yak-130 is a Russian-made advanced jet trainer and light combat aircraft developed by Yakovlev and manufactured by Irkut Corporation. Iran acquired a fleet of Yak-130s as part of its military equipment deals with Russia — a relationship that has deepened considerably since the outbreak of the Russia-Ukraine conflict, during which Iran supplied Russia with Shahed-136 drones in exchange for military hardware and technical cooperation. The Yak-130 is primarily designed to train pilots transitioning to advanced Russian combat jets including the Su-30, Su-35, and Su-57. However, it is also capable of performing light attack and limited air defence missions, equipped with multiple external hardpoints that allow it to carry guided bombs, rockets, and short-range air-to-air missiles. Iran's use of the type in air patrol roles over Tehran reflected the degraded state of its heavier combat aviation — with Israeli strikes having targeted Iranian fighter jets on the ground in the opening days of the operation. Israel's First Air-to-Air Kill Since 1985 The engagement is significant not only for what it means for the F-35 programme globally, but for what it means for the Israeli Air Force historically. The last time an IAF fighter jet shot down a manned enemy aircraft in combat was on November 24, 1985 — over Lebanon — when an IAF F-15 downed two Syrian MiG-23 fighters. That engagement happened more than 40 years ago. Wednesday's kill over Tehran ends four decades of Israeli air supremacy without a single air-to-air engagement involving manned aircraft — a testament to how completely the IAF has dominated the skies over every conflict it has been involved in during that period. What It Means for the F-35 Programme For Lockheed Martin, the US Department of Defense, and the more than a dozen allied nations that operate the F-35, Wednesday's engagement is an enormously significant proof of concept. The F-35 has been the most expensive weapons programme in history — with lifetime programme costs estimated at over $1.7 trillion — and has faced years of criticism over cost overruns, software delays, and questions about its combat effectiveness compared to fourth-generation fighters. A confirmed air-to-air kill against a manned aircraft in active combat, achieved by the world's most advanced stealth fighter in the most contested airspace on earth, answers those questions in the most direct way possible. Day 5: The War Continues The Yak-130 shootdown is the most dramatic single event of Wednesday's operations — but it is far from the only development. The IDF confirmed it launched its tenth wave of strikes on Tehran, targeting infrastructure belonging to the Iranian regime including Basij and internal security command centres. Israel has also threatened to assassinate Iran's next Supreme Leader — whoever the Provisional Leadership Council selects — if the conflict is not resolved. Iran's Revolutionary Guard confirmed the launch of a 17th wave of missiles targeting Israel. The war that began five days ago shows no signs of resolution.
