Iran revealed on Sunday a new missile, named Sayyad 4B, which is conformant with Iran’s homegrown air defense system Bavar-373 with a range of 300 kilometers.

With specifications such as its optimized radar and an engine that runs on hybrid solid fuel, a recent test-run proved the air defense system's ability to locate the target at a range of more than 450 km and to track it at a distance of around 405 km before detonating it with the new Sayyad 4B.

The range of the detection radar of Bavar 373 increased from 350 to 450 km, whereas its tracking range has risen from 260 to 400 km. The Bavar-373 was first unveiled in August 2019. Iran's long-range air defense system is capable of detecting up to 100 targets, tracking 60, and engaging with six at the same time.

Through Sayyad 4B, the air defense system missiles can be extended up to 300 km alongside an increase in altitude of engagement from 27 to 32 km.

Iranian military technicians and experts have advanced the country's military capabilities that in September, the commander of Iran's air forces, Brig. Gen. Hamid Vahedi, said Iran has achieved full self-sufficiency in supplying its air forces with combat unmanned aerial vehicles (UAVs). 

Iran has developed an advanced long-range suicide drone "designed to hit Israel's Tel Aviv, Haifa," Iranian news agency Mehr reported. Brigadier General Kiomars Heidari said last month that the drone, named Arash-2, is a newer version of Arash-1, and it is designed to target the cities of Iran’s enemy "Israel".

Iran stands its ground that no threat is posed by its military to regional countries, emphasizing that its defense doctrine is founded on deterrence.
