removing restrictions on working time. They destroyed a UAV target beyond 100 km range in military drill in recent years. They use two new solid propellant missile named Sayyad-2 and Sayyad-3 via interface systems Talash-2 and Talash-3 in cooperation with S-200 system. These missiles can cover medium and long ranges at high altitudes. Also, Iran claims to have developed a mobile launcher for the system. Operational history Ukraine A Ukrainian S-200 operated by the Ukrainian military during a Ukrainian training exercise fired on a Tupolev Tu-154 passenger aircraft flying from Tel Aviv to Novosibirsk, Siberia Airlines Flight 1812. The airliner was destroyed over the Black Sea on 4 October 2001, killing all 78 people on board. Libya Starting in 1985, Libya received a number of S-200 missile systems. In the following months, Libyan forces fired a number of S-200 missiles in different occasions at US fighter-bombers, missing them. In the USSR, three organizations (CDB Almaz, a test site and a research institute of the Ministry of Defense) conducted computer simulation of the battle, which gave the probability of hitting each of the air targets (3) in the range from 96 to 99%. Syria Starting in January 1983, Syria received supplies of S-200 missiles from the Soviet Union. They were organized into two long range surface to air missile regiments, each composed of two battalions of two batteries each for a total of at least 24 launchers. Later in the 1980s, the Soviet Union agreed to supply a third regiment increasing the number of launchers to 40–50. Initially the missiles were manned by Soviet crews, later they were transferred to Syrian control. As such, Syria became the first country outside the Soviet Union to field the S-200 system. During the initial years of the Syrian civil war, parts of the S-200 systems were occasionally spotted when Syrian Air Defense Force sites were overrun by rebel forces. Most notably radars, missiles and other equipment from S-200 systems was pictured in a state of disrepair when rebels overtook the air defense site in Eastern Ghouta in October 2012. On 2 January 2017, the Syrian Army re-captured this air defense base. Starting with the Russian intervention in the civil war in late 2015, there were new efforts to restore some Syrian S-200 systems. Indeed, on 15 November 2016, the Russian defence minister confirmed that Russian forces repaired Syrian S-200s to operational status. For example,
