Iran Unveils Sayad-4 Electronic Warfare System After June War Setbacks

On 10 December 2025, Iran has unveiled a new electronic warfare and air-defence radar system known as Sayad-4, signalling a shift in military priorities following the June war and the Israeli-American hammering that accompanied it. The system was presented at a defence exhibition in Tehran and aired by IRIB, Iran’s state broadcaster.

Due to security restrictions, only a replica of the system was displayed. Defence officials said the measure reflects the platform’s operational sensitivity, adding that Sayad-4 has already been developed and evaluated by the Ministry of Defence.

Sayad-4 is described as a hybrid platform combining electronic warfare and air-defence radar functions, designed to operate in high-intensity electromagnetic environments. Iranian media report that the system can disrupt positioning, navigation and timing networks, including satellite navigation systems used by aircraft, drones and precision-guided munitions.

Defence sources claim the system can jam, deceive and degrade hostile signals while maintaining its own radar performance. Key features reportedly include multi-band radar operation, anti-jamming resistance and network-centric data sharing, allowing coordination with missile batteries, command centres and other radar nodes.

According to Mehr News Agency, Sayad-4 was designed and built by female scientists and engineers working within Iran’s defence industry. The system was unveiled at an exhibition highlighting women-led defence achievements.

Defence Minister Brigadier General Aziz Nasirzadeh and other senior military officials reviewed the system, describing it as a boost to Iran’s indigenous capabilities.

The unveiling follows the June conflict, during which Israeli and American forces reportedly conducted air strikes, electronic warfare and cyber operations against Iranian and Iran-aligned targets. Iranian commanders later acknowledged weaknesses in radar coverage, command-and-control networks and navigation-dependent systems.

Officials say Sayad-4 incorporates lessons learned from the June war, when advanced jamming, precision strikes and electromagnetic suppression strained Iran’s defensive networks. The system is intended to ensure continued detection, disruption and survivability under sustained electronic attack.

The announcement comes amid heightened tensions with Washington and Tel Aviv, as Iran emphasises a more layered defence posture. Analysts note that electronic warfare has become central to Iran’s military doctrine, enabling it to counter technologically superior adversaries by degrading situational awareness, communications and navigation.

While independent verification of Sayad-4’s full capabilities remains limited, its unveiling signals Iran’s determination to adapt to modern warfare and address vulnerabilities exposed during the June war.
