Iran Rejects Tor As Replacement For S-300 Air Defense System

Iran has rejected a Russian proposal to substitute the Tor (NATO: SA-15) short-range air defense system for the S-300 (NATO: SA-10) long-range air defense system.

Iran had originally ordered the S-300-PMU1 in 2007. The $800 million contract was then cancelled by Russia in 2010. In 2011, Iran launched a $4 billion lawsuit against Russia over the cancellation.

Iran insists that Russia fulfill the original contract and deliver the S-300 as agreed. It will only withdraw the lawsuit when Russia agrees to honor the contract that was signed.

While Iran has yet to receive the S-300, it already has the Tor-M1 system. In 2005, 29 Tor-M1 systems were ordered for $700 million. All were delivered by 2007.

The Tor-M1 is a short-range, all-weather, surface-to-air missile air defense system that can engage aircraft, unmanned aerial vehicles, cruise missiles and other precision guided munitions.

The tracked Tor-M1 vehicle carries 8 vertically cold-launched 9M331 missiles. Each 9M331 has a:
  • Length of 2900 mm
  • Diameter of 235 mm
  • Weight of 167 kg
  • Warhead of 15 kg
  • Speed of 850 m/s
  • Range of 12000 m
  • Ceiling of 6000 m
The Tor-M1 vehicle carries its own target acquisition radar with a range up to 25 km, a tracking radar in addition to a optical tracking system.

The latest version, the Tor-M1 features a number of improvements, including:
  • new phased array radar
  • improved missiles
  • improved electronic counter measures
  • improved infrared tracking system
  • increase in the number of targets that can be engaged simultaneously
The Tor-M2 also features a new wheeled chassis.
