The Iranian military unveiled the longer-range Sayyad-4B surface-to-air missile (SAM) for its Bavar-373 air-defence system on 6 November.
The missile was unveiled during a ceremony attended by Minister of Defence Brigadier General Mohammad Reza Ashtiani and Islamic Republic of Iran Air Defense Force (IRIADF) Commander Brigadier General Alireza Sabahifard.
The Iranian media reported that the missile has successfully engaged a target at more than 300 km during a test, up from the 200 km earlier achieved. It was also reported that the missile's maximum altitude has been increased from 27 to 32 km.
The Bavar-373 radars have also been improved, and during the test detected the target at a distance of 450 km, up from 350 km, and tracked it at 405 km, up from 260 km.
The Tasnim News Agency quoted Brig Gen Sabahifard as saying that the target drone was destroyed at an altitude of 40,000 ft (12.2 km).
In October, the IRIADF commander was quoted as saying that trials of the Bavar-373 had begun at a range of 300 km.
The Iranian military has not yet announced that the system has entered service, although it is being promoted as an export product under the name AD-200. The brochure states that the Sayyad-4 missile has a length of 7,500, a diameter of 515 mm, a total weight of 2,050 kg with a warhead of 180 kg. It uses inertial mid-course guidance that is updated by the system via a datalink and uses either a semi-active or active radar homing in the terminal phase.
