The S-300V air defence missile system was developed to engage short and intermediate range ballistic missiles, cruise missiles, strategic and tactical aircraft, as well as early warning and electronic warfare aircraft. It was designed to counter the threat posed by Lance and Pershing ballistic missiles. The main role of the S-300V is to protect task forces and vital industrial and military installations against massed air attacks. Its reporting name in the West is SA-12 or Gladiator/Giant. Some components of the S-300V system were deployed in 1983. All components entered service with the Soviet Army in 1988. Recently it has been reported that production of all S-300 series missiles, including export versions, will be stopped in Russia in favour to the newer S-400. The S-300V is a mobile air defence system. All of its elements are mounted on special tracked chassis. The first production version of the S-300V had a range of 100 km and could reach targets at an altitude of 30 km. It could engage ballistic missiles at an altitude of 25 km.
