The F-15 Saudi Arabia crash was allegedly caused by the Iranian Krasukha-4 system, although this is simply a hypothesis that needs additional support.

According to reports, Iran tested a Russian Krasukha-4 electronic warfare weapon on a Saudi F-15 fighter from a distance of 400 kilometres, forcing the aircraft to crash. However, the preliminary release stated that the plane’s control system had been completely damaged, which is extremely usual for operations electronic warfare group. It is noteworthy that the Saudi authorities carefully disguised the occurrence for about two weeks. Records from the location show that the aforementioned fighter quickly lost altitude before crashing to the ground; nevertheless, there was no indication that it had been hit by anti-aircraft fire from the outside.
It is also extremely noteworthy as Iran declared at the time that it had just obtained from Russia the Krasukha-4 ultra-long-range electronic warfare system and acknowledged that it had been tested on foreign fighters. Local self-defense forces have advanced significantly recently, according to Afshin Naderi Sharif, Iran’s deputy defence minister in charge of industrial and research affairs. An enemy aircraft object cannot readily enter the nation’s airspace without being picked up by radar due to the efficacy of sky defence.

“At a distance of 400 km, we jammed enemy spy planes. Additionally, the enemy is aware that the Islamic Republic of Iran’s defence sector has acquired this knowledge “As reported by the Tasnim news agency. This information does not rule out the potential that Iran may have attacked the Saudi fighter plane with its Krasukha-4 electronic warfare system, particularly if we consider the probability that the fighter crashed as a result of an erroneous control system.
The radar on the US Air Force’s E-3 Sentry airborne early warning and control aircraft (AWACS) and spy satellites are only two examples of the kinds of huge radar stations that the Krasukha-4 electronic warfare complex is designed to find and jam. Despite being under development since the late 1990s, Krasukha-4 is still one of the Russian Army’s most effective mobile EW systems, and mass manufacturing only started in the early 2010s.
The development of Krasukha-4 was a component of a broader field system project that included numerous radar-equipped intelligence satellites and was intended to protect Russian assets from the prying eyes of ground and air surveillance radars. The Krasukha-4 can detect and jam a variety of radars, including surveillance radars, aerial radar image sensors, active radar detectors, and machines altimeter in the rocket, according to at least one previous claim made by Russian officials. The Krasukha-4’s maximum range against ground and air targets, depending on numerous environmental circumstances, is between 150 and 300 kilometres in any direction, according to the manufacturer KRET. Some sources assert that the Krasukha-4 jamming device is capable of emitting an energy beam strong enough to physically harm some targets’ delicate electronics.
Analysts claim that there is no concrete evidence to support any connection between the latest incident and the operation of the Iranian Krasukha-4 complex and the downing of the Saudi Air Force’s F-15 jet; all of this is merely conjecture.
