Iran's F-35 'hit' claim shakes the myth of US 'sky ghost' - why it could be a turning point

A US F-35 stealth fighter has been damaged during a combat mission over Iran, forcing an emergency landing at a US air base in the Middle East, according to American officials. The pilot survived and is in stable condition, but the incident is now under investigation.

The development comes as Iran claimed it had successfully struck the aircraft using its air defence systems, potentially marking the first time Tehran has hit one of the United States’ most advanced jets during the ongoing conflict. The claim has not been fully confirmed by Washington, but US officials have acknowledged the aircraft was hit by what is believed to be Iranian fire.






Capt Tim Hawkins, a spokesperson for US Central Command, said the fifth-generation jet was “flying a combat mission over Iran” when it was forced to land. “The aircraft landed safely, and the pilot is in stable condition,” he said, adding that the matter is being investigated.

Why this is a big deal: the F-35 factor

The F-35 Lightning II is not just another fighter jet it is widely regarded as the backbone of US and allied air power and one of the most advanced combat aircraft ever built.

Costing upwards of $100 million per unit and operated or ordered by more than 19 countries, the F-35 is the world’s most widely deployed fifth-generation fighter. It combines stealth, advanced sensors and networked warfare capabilities in a way that fundamentally reshapes how air combat is fought.

At its core is stealth. The aircraft is designed to evade radar detection through its shape, materials and internal weapons bays, allowing it to operate deep inside heavily defended airspace. In theory, this makes it extremely difficult for enemy air defences to track or target.

Equally important is sensor fusion. The F-35 does not simply gather data it processes and merges inputs from radar, infrared sensors, satellites and other aircraft into a single real-time battlefield picture. This allows pilots to detect threats earlier and engage targets before being seen.

The jet is also built for network-centric warfare. It operates as part of a wider digital combat system, sharing data with other aircraft, ships and ground systems. In such a setup, the F-35 is not just a fighter but a node in a larger warfighting network.

This combination — stealth, sensor fusion and networking is what defines a fifth-generation fighter. Only a handful of nations possess such aircraft at scale, with the US leading through the F-35 programme.

That is why even a partial hit is significant. If Iranian air defences were able to track and strike an F-35, it could suggest improvements in detection systems or exploitation of gaps in US operations. It also challenges the perception that stealth aircraft can operate with near impunity.

At least 16 US aircraft have been lost since the war began, including multiple MQ-9 Reaper drones shot down by Iranian defences, as per a report by Bloomberg. These drones are designed to be expendable and are frequently used in high-risk missions.

Other losses have stemmed from accidents and friendly fire. Three F-15 fighter jets were mistakenly shot down by Kuwaiti air defences, with all crew members ejecting safely. In another incident, a KC-135 refuelling aircraft crashed in western Iraq, killing all six personnel on board. The US military said the crash was not caused by hostile action.

Despite these setbacks, US officials maintain that operations are proceeding as planned. However, analysts point out that the US has only achieved “localised air superiority” in parts of Iranian airspace, rather than full dominance.

Iran, meanwhile, continues to launch regional strikes, including attacks on energy infrastructure, while claiming to have downed large numbers of US and Israeli drones. It says the F-35 strike reflects upgrades to its integrated air defence network.

How Iran’s infrared systems may have struck the ‘ghost of the skies’

Iran’s claim that it struck a US F-35 Lightning II has drawn sharp global attention, with early indications suggesting that infrared-guided air defence systems may have played a role in the incident now under investigation.

A US F-35 stealth fighter was damaged during a combat mission over Iran and forced to make an emergency landing at a US air base in the Middle East, according to American officials. The pilot survived and is in stable condition. While Washington has not fully confirmed Tehran’s claim, it has acknowledged the aircraft was hit by what is believed to be Iranian fire.

Iran has described the incident as a “world’s first hit”, raising questions about how one of the most advanced stealth aircraft may have been tracked and targeted.

Infrared systems in focus

Analysts are increasingly looking at Iran’s infrared-guided surface-to-air systems, which rely on heat signatures rather than radar, as a possible factor.

Among the key systems:

• Misagh-2: A locally developed shoulder-fired missile with a range of around 6 km, designed to lock onto an aircraft’s heat signature.
• Majid: A newer short-range system using electro-optical and infrared tracking, built for point defence against low-flying targets.
• Herz-9: A passive, mobile air defence system that tracks targets without emitting radar signals, making it harder to detect.
• Misagh-1 and Misagh-3: Earlier and upgraded variants of Iran’s heat-seeking missile family.
• Sayyad-1A: An upgraded anti-aircraft missile believed to incorporate infrared tracking elements.

Unlike traditional radar-guided systems, these platforms operate passively, meaning they do not broadcast signals that stealth aircraft are designed to evade. This raises the possibility that infrared detection may have complemented or substituted radar tracking in the engagement.

Can infrared systems hit an F-35?

The F-35 is built to minimise both radar and infrared signatures, but it is not completely invisible. Its engine still produces heat, particularly during high-speed or combat manoeuvres.

Infrared-guided systems, in theory, can exploit this by:

• Locking onto engine exhaust heat
• Tracking targets without radar emissions
• Engaging aircraft at short to medium ranges

However, such a hit would still be considered highly challenging. The F-35 is equipped with advanced countermeasures, including flares and electronic warfare systems, and is designed to detect threats early through its sensor fusion capabilities.

What makes this incident significant

Capt Tim Hawkins, spokesperson for US Central Command, said the fifth-generation jet was “flying a combat mission over Iran” when it was forced to land. “The aircraft landed safely, and the pilot is in stable condition,” he said.

Even a partial strike carries weight. The F-35 is widely seen as one of the most survivable aircraft in contested airspace due to its stealth, sensor fusion and network-centric warfare design.

If Iranian systems were able to track and hit the jet, it could point to:

• Improved passive detection capabilities
• Effective use of layered air defence networks
• Potential operational vulnerabilities in high-threat environments
• Iran has claimed the strike reflects upgrades to its integrated air defence network, though details remain unclear.

The bigger picture

The reported hit comes amid an ongoing conflict in which the US has lost at least 16 aircraft, including multiple MQ-9 Reaper drones, according to a Bloomberg report. Other losses have been attributed to accidents and friendly fire.

While US officials maintain that operations are proceeding as planned, analysts note that only “localised air superiority” has been achieved in parts of Iranian airspace.

Against this backdrop, Iran’s claim of striking an F-35 — whether through infrared systems alone or in combination with other tracking methods — could mark a shift in how stealth aircraft are challenged in modern warfare.
