Iran tests 'super-fast' torpedo
Iran has tested what it says is the world's fastest underwater missile, designed to elude radar and destroy enemy submarines.
Iran's elite Republican Guard troops are carrying out a series of military exercises and tests in the Gulf and in the Arabian Sea.
The new missile, called Hoot, or Whale, could be deployed on Iranian ships in the oil-rich area, which is home to the US 5th Fleet.
It is said to travel at 360km/h (233mph), three to four times faster than most conventional torpedos.
"It has a very powerful warhead designed to hit big submarines," Gen Ali Fadavi," deputy head of the Revolutionary Guard, told the Associated Press.
"Even if enemy warship sensors identify the missile, no warship can escape from this missile because of its high speed."
