Iran’s navy said Monday, December 31 it test-fired a range of weapons during ongoing maneuvers near the Strait of Hormuz, the passageway for one-fifth of the world’s oil supply, the Associated Press reported. Adm. Amir Rastgari, spokesman for the exercise, said the Iranian-made air defense system Raad was among the weapons tested, along with various torpedoes and underwater and surface-to-surface rockets as well as anti-ship missiles. Iran’s military leaders have recently said they believe future wars will be air- and sea-based and Tehran has sought to upgrade its air defense systems and naval power in anticipation of such a possibility. The maneuvers come as the West increases its pressure over Iran’s nuclear program. Iran has repeatedly threatened to close the strategically important strait over Western sanctions or military threats against its nuclear facilities.
