Iran has been dedicated to developing indigenous weapons programs that do not depend on external supplies for decades. From rifles to ballistic missiles have been developed with different success, and in the case of the Soumar cruise missile, it seems that success is remarkable. In 2015, it was announced the mass production of this missile derived from the Russian Kh-55 missile. Iran illegally bought twelve examples to Ukraine in 2005 and since then, a reverse engineering program has been initiated to produce these missiles in the country. According to the Iranians, the missile has similar capabilities to the Kh-55, but those sold by Ukraine did not have the R95-300 turbofan engine and did not mount the counter matching (TERCOM) navigation system, so it is doubtful that without these systems the Soumar has the same capabilities. The Soumar does not have capacity to carry nuclear warheads due to its small size, but this cruise missile have sufficient range to attack Israel and all the American military bases in the Middle East, which is enough of a threat to destabilize the area at any given time.
