On November 6, the Iranian military unveiled a new long-range anti-aircraft missile for the domestically-developed Bavar-373 air-defense system.
The new missile, dubbed Sayyad 4B, was showcased during a ceremony that was attended by Iran’s Minister of Defense, Brigadier General Mohammad Reza Ashtiani, Commander of Iran’s Army Air Defense Force, Brigadier General Alireza Sabahifard, and a group of Iranian defense industry experts.
Speaking at the ceremony, Brig. Gen. Sabahifard said that Iran is one of the few countries in the world that has been able to produce such air-defense systems.
“As much as the threats advance, the Bavar-373 system and other air defense systems advance ahead of the current threats,” he said.
The Sayyad 4B, which is propelled by a hybrid solid fuel engine, has a range of 300 kilometers and an engagement altitude of up to 32 kilometers.
To make use of the new missile, the range of the detection radar of the Bavar-373 system was increased from 350 to 450 kilometers, while the range of its tracking radar was increased from 260 to 400 kilometers.
In a recent test, the Bavar-373 system successfully hit an aerial target at a distance of over 300 kilometers with a Sayyad 4B missile. The air-defense system managed to detect the target at a range of more than 450 kilometers and track it at a distance of around 405 km before engaging it with the new missile.
Not much is known about the guidance system of the Sayyad 4B. It is suspected that the missile utilizes a complex guidance technique known as track-via-missile, which combines features of semi-active radar homing and radio command guidance.
The Sayyad 4B will without a doubt boost the air defense capabilities of Iran. The country has been working to locally develop these capabilities for a long while.
