The Jerusalem Post reports that Russia has delivered Tor-M1 air defense missile systems to Iran. The contract calls for a total of 29 missile systems at a cost of $700 million. The United States opposed the sale, apparently to no effect.
The system is designed to protect installations against cruise missiles, such as the US Tomahawk, fixed-wing aircraft, and precision-guided munitions. It would fit perfectly as part of a system to defend nuclear installations against an attack from the US or Israel. Although the UN has voted sanctions against Iran as a result of her defiant pursuit of nuclear weapons, they don’t appear to apply to non-nuclear defensive weapons systems.
