Iran has obtained the technology to build a supersonic cruise missile, which is still under test, the semiofficial Tasnim news agency reported on August 9. The announcement comes amid rising tensions with the United States in the Persian Gulf and following the unveiling last week of new vessels equipped with 600-kilometer-range missiles. "This missile, which is a new generation of Iranian-made cruise missile, is currently undergoing its tests and will be a new chapter in Iran's defense power," the agency said.
