From today's Telegraph. http://www.telegraph.co.uk/news/main.jhtml?xml=/news/2006/04/03/wiran03.xml&sSheet=/news/2006/04/03/ixworld.html Iran sends a message to the West by boasting about its high-speed torpedo By Tim Butcher, Middle East Correspondent (Filed: 03/04/2006) Iran announced that it has carried out successful test-firings of the world's fastest torpedo, capable of outrunning any warship. The message was intended as a signal to western military planners considering attacks to deal with Iran's nascent nuclear capability. While military plans remain secret, it is believed that Washington, London and Tel Aviv have begun drawing up options ranging from surgical air strikes to helicopter-borne commando raids. A new torpedo of the speed and capability described by Ali Fadavi, a rear admiral of the Revolutionary Guards, would not be used to combat western warships involved in an attack on Iran but to punish western military action by crippling the world's oil supply. Iran holds the northern side of the Straits of Hormuz, the narrow neck in the Persian Gulf through which two fifths of the world's traded oil passes. A hi-tech torpedo could be used with devastating effect against oil tankers and western warships sent to protect them, choking off the world's oil supply, driving up prices and causing global economic chaos. "This device evades sonar technology under the water and even if the enemy's sonar system could detect its movement, no warship could escape from it because of its high velocity," Admiral Fadavi said. "The Islamic Republic is now among only two countries who hold this kind of missile." He did not name the other. "Under water, the maximum speed that a missile could move was 25 metres per second. But now we possess [one] that goes as fast as 100 metres per second. "It carries a very powerful warhead that enables it to operate against groups of warships and big submarines." Iran is known to have a number of Kilo-class submarines. Built in Russia, they are relatively sophisticated hunter-killer boats, designed to sneak up on enemy shipping, attack with torpedoes and escape. Iran lied to the international community for more than 10 years about its nuclear capability, denying that it had any technology or ambitions. Intelligence leaks to the West eventually forced Teheran to admit that it had a relatively advanced nuclear programme but even now it insists that this is purely to generate energy. It flatly denies any military ambitions. There has been a significant toughening of the language used by western diplomats about Iran recently.
