Sayyad II is a new development of the Iranian defense industry. Although it follows Sayyad I in name, there are no similarities in appearance or in internal parts.
While Sayyad I is a missile 10.8 meters long, weighs 2,326 kg, and uses two-stage propellant, the first solid which is used as accelerator and the second liquid used as fuel for the main engine, Sayyad II is a slender object with one solid propellant.
It seems that Sayyad II is modeled on the American missile the standard RIM-66, also known as SM-1, with touches of locally conscious considerations and the like.
The missile is about 20 to 25 cm longer than the American twin which makes it look more like rather modern samples.
Sayyad II is a mid-range, high-flying missile whose range seems to be much more than Sayyad I.
It enjoys a hybrid guidance system with an independent target and follow option.
The Army Air Defense Base commander has stated that Sayyad II has been highly successful in targeting small flying objects.
Besides similarities sit has with the Patriot both in appearance and function, and the fact that they are both designed to defend fixed strategic facilities, Sayyad II is launched from a launcher much similar to Patriot’s.
