俄罗斯防空导弹系统制造商主管星期五对记者说，他的公司运送了15组S-300防空导弹。
根据俄罗斯媒体的报导，一组S-300防空导弹通常包括四个车载装置。每个装置配有四枚导弹。伊朗也签署了从俄罗斯购买地对空导弹系统的合同。但是购买计划被多次推迟。
俄罗斯将推迟兑现购买合同归咎于技术原因，但是伊朗官员怀疑真正原因是美国和以色列施加压力。这两个国家强烈反对向伊朗出售导弹。这些导弹有可能被用来阻挠针对伊朗核设施的空袭。
The director of the Russian manufacturer of the system (Igor Ashurbeili) told reporters Friday that his firm has delivered 15 units of the S-300. According to Russian media, one unit of the S-300 typically consists of four truck-mounted installations, each containing four missiles.Iran also has a contract to buy the surface-to-air missile system from Russia, but the exchange repeatedly has been postponed.
Russia blames technical problems for the delays, while Iranian officials suspect pressure from the United States and Israel. The two countries have strongly objected to the sale of the missiles, which potentially could be used to thwart air attacks against Iranian nuclear sites.
