Iran develops Integrated Air Defense Network, deployed Russian S-300 systems integrated with indigenous Air Defense systems

Iran’s air defence command conducted what was billed as the first test launch of the indigenously developed Talash air defence system on 28 December 2016. The tests began with the launch of Iranian-made Sayyad-2 medium-range, high-altitude surface-to-air missile. The Sayyad-2 is a canister-launched version of the RIM-66 (SM-1) naval surface-to-air missile that Iran obtained from the United States before the 1979 revolution. The Fars news agency reported that the Talash system uses the indigenously developed Ofogh (or Ofoq) fire control rada,r which calculates the path for missiles to hit targets.  The launches were  part of an exercise dubbed ‘Defenders of Velayat Skies 7,’ which was seen as signal to potential adversaries such as Saudi Arabia, Qatar, and even the US,  that Iran has power and ability to defend itself.
