Israel Claims World’s First F-35 Fighter Kill with Shootdown of Iranian Yak-130: Is It Credible?

The Israeli Air Force has reported the successful shootdown of an Iranian Air Force Yak-130 combat trainer over the capital Tehran, as part of its sustained military offensive launched alongside the Untied States on February 28 which is aimed specifically at toppling the Iranian government and installing a Western-aligned replacement. The shootdown, if confirmed, would represent the first ever achieved by the F-35 against a manned aircraft, making it the second fighter of its generation to have achieved this. The Russian Su-57 fifth generation fighter was previously credited with a number of shootdowns of Ukrainian aircraft from 2023, although these also remain unconfirmed. Significant questions nevertheless remain regarding the veracity of Israeli claims, with the fabrication of a shootdown also having significant public relations benefits as Israel and the U.S. have been faced with significant setbacks. 

The announcement of the shootdown of a Yak-130, which is by far the most modern type of manned combat jet in Iranian service, closely followed Iranian sources’ announcement of the successful shootdown of an F-35 near Tehran, raising the possibility that it may have been made to divert attention away from the Iranian claim. The ability of the F-35 to achieve the shootdown remains in question for a number of reasons, primarily because it would require the fighters to operate deep inside Iranian airspace. Israeli and U.S. fighters have primarily operated from well beyond the country’s borders to launch ballistic and cruise missiles from safe distances, avoiding engaging the country’s vast air defence network, with Iran’s widely distributed infrared guided air defence systems posing a particular threat. Operating the F-35 deep inside Iran at such an early stage in the war, and firing air-to-air missiles which would increase the fighter’s radar cross section and heat signature in a heavily defended area of the country, thus would be a very high risk operation that is out of line with how Israeli fighter operations have generally been conducted.

Israeli Air Force officers have noted that without an air-to-ground missile capability, which is only expected to be achieved when fighters are brought up to a Block 4 standard in the early 2030, the F-35 has been relegated primarily to intelligence collection roles using its powerful sensors to serve as a force multiplier for fourth generation fighters. Thus deploying the fighters for a deep penetration operation into Iran to shoot down fighters over the capital would appear highly out of line with how the fighters have been operated. The F-35 is the only new fighter type Israel has introduced into service since the 1970s, and as a result public relations efforts have focused very heavily on promoting its capabilities, at times leading to the publication of highly implausible stories particularly during its first months in service in 2016-2017. While the shootdown of a Yak-130 fighter is not impossible, it is also highly plausible that the report is part of public relations effort intended to strengthen the image of the Israeli Air Force, and of the F-35, while raising morale as the war takes an unprecedented toll.
