WANA (Apr 24) – In recent hours, the sound of air defense systems in Tehran and several other Iranian cities has drawn public attention, prompting questions about its cause. According to available information, the activity was primarily a response to the presence of micro aerial vehicles and small drones, including models known as “Orbiter,” detected in different parts of the country.

 

Reports indicate that the activation of air defense systems under the current ceasefire conditions reflects a state of full operational readiness, in which any suspicious movement or aerial signal is closely monitored and, if necessary, met with an immediate response.

 

A military affairs expert, commenting on the situation, outlined several contributing factors behind the increased air defense activity. First, he noted that during a ceasefire period, operators remain on high alert and are required to react to any unusual light, object, or signal in the sky.

 

He further explained that fighter jets, such as the MiG-29, are commonly used as part of the capital’s defensive perimeter to monitor and intercept aerial threats, including drones. As such, some of the sounds reported may be linked to routine aerial surveillance missions by these aircraft.

 

The expert also pointed to technical and maintenance operations as another factor, stating that ceasefire periods provide an opportunity for overhauling air defense systems, installing new radar equipment, and testing repaired or upgraded systems—processes that inevitably involve operational testing.

 

Finally, he highlighted a shift in Iran’s air defense deployment model, from a centralized, network-based “spider” system to a more decentralized “mosaic” structure. This newer approach emphasizes localized and independent units, and the ceasefire period is being used to train and consolidate this configuration.

 

Overall, a combination of operational vigilance, technical activities, and limited aerial threats appears to have contributed to the recent air defense activity, within the broader context of a sensitive ceasefire environment.
