Zolfaghar
On September 25, 2016, Iranian Defense Minister Hossein Dehghan announced that Iran’s new Zolfaghar ballistic missile, a Fateh-110 variant, has a potential range of 700 km. The latest member of the Fateh-110 family of solid-fueled short-range ballistic missiles, Iran claims that Zolfaghar is equipped with a sub-munition warhead. The Iranian Ministry of Defense released a video allegedly showing the Zolfaghar being fired and successfully hitting a tiny target. The authenticity of the video has not been verified.
Fateh-110 Anti-Ship Variants
In 2014, the IRGC displayed two variants of the Fateh missile it called the Hormuz-1 and Hormuz-2. The Hormuz-1 is claimed to have anti-radiation capabilities for attacking radar systems, and in 2014, Iranian television broadcast images of commanders watching an attack on a target with radar antennae. The original claim was that Hormuz-2 was an anti-ship variant. Still, images of the missile suggested it had a similar radio frequency-transparent ray dome and not a window for an electro-optical infrared seeker, suggesting it is essentially the same as the Hormuz-1.
Another anti-ship variant of the Fateh is the Khalij Fars, which has the electro-optical seeker required to improve accuracy enough to potentially hit a moving target. Tehran claims that the early version of Khalij Fars entered service in 2008, but was not officially delivered to the Iranian military until a ceremony in March 2014. This ceremony featured Fateh missiles painted blue to suggest an anti-ship variant, but Iran put caps on the noses of the rockets, preventing verification of the EO/IR seekers. The Department of Defense assessed in the unclassified version of its 2014 report on the military power of Iran that it does possess an anti-ship ballistic missile capability.
